|
In September, doctors were concerned after an ultrasound showed that one of the best sources of blood flow in her left leg, her left popliteal artery, was closed.
|
|
They thought she would need another emergency surgery, but decided to wait, and a second ultrasound showed that ten new arteries and grown to replace that popliteal artery, and continue her blood flow.
|
|
Love and Whelan proposed a classification of this pathology into four types, according to the various relationships between the popliteal artery and the muscles of the popliteal space. Rich and Hughes described popliteal vein compression, thus adding a fifth type into the former classification. The functional type of the popliteal vessel compression was first described by Rignault et al. in 1985 and labeled by Levien as type VI of the popliteal vessels entrapment syndrome.
|
|
Abnormality in the relationship between the adductor hiatus and the popliteal artery can also contribute to a condition called popliteal artery entrapment syndrome.
|
|
Popliteal pterygium syndrome (PPS) is an inherited condition affecting the face, limbs, and genitalia. The syndrome goes by a number of names including the popliteal web syndrome and, more inclusively, the facio-genito-popliteal syndrome. The term PPS was coined by Gorlin et al.. in 1968 on the basis of the most unusual anomaly, the popliteal pterygium (a web behind the knee).
|
|
This small branch of the Popliteal artery pierces the oblique popliteal ligament, and supplies the ligaments and synovial membrane in the interior of the articulation.
|
|
Commonly, pseudothrombophlebitis is caused by rupture of a popliteal cyst causing leakage of synovial fluid, leading to inflammatory irritation to the gastrocnemius muscle. Pseudothrombophlebitis is not the only possible consequence of a popliteal cyst. The existence of a large popliteal cyst can be a risk factor for deep vein thrombosis. Furthermore, a ruptured popliteal cyst may cause compartment syndrome in the calf or even the thigh.
|
|
For British people, the median popliteal height is 440 millimetres for men and 400 mm for women, while Japanese men have a popliteal height of 400mm and women 360mm.
|
|
The articular branch for the knee-joint is sometimes absent; it either perforates the lower part of the Adductor magnus, or passes through the opening which transmits the femoral artery, and enters the popliteal fossa; it then descends upon the popliteal artery, as far as the back part of the knee-joint, where it perforates the oblique popliteal ligament, and is distributed to the synovial membrane. It gives filaments to the popliteal artery.
|
|
The popliteal artery entrapment syndrome is a rather uncommon pathology, which results in claudication and chronic leg ischemia. The popliteal artery may be compressed behind the knee, due to congenital deformity of the muscles or tendon insertions of the popliteal fossa. This repetitive trauma may result in stenotic artery degeneration, complete artery occlusion or even formation of an aneurysm.
|
|
Differential diagnoses include; popliteal cyst, adventitial cyst, lymphadenopathy, varicose vein.
|
|
Sometimes the SSV joins the common gastrocnemius vein before draining in the popliteal vein. Sometimes it doesn't make contact with the popliteal vein but goes up to drain in the GSV at a variable level. Instead of draining in the popliteal vein it can merge with the Giacomini vein and drain in the GSV at the superior 1/3 of the thigh.
|
|
Lymphadenopathy of popliteal, prescapular, submandibular and inguinal lymph nodes was also found.
|
|
The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries. The deepest (most anterior) structure in the fossa, the popliteal artery runs close to the joint capsule of the knee as it spans the intercondylar fossa. Five genicular branches of the popliteal artery supply the capsule and ligaments of the knee joint.
|
|
The two most relevant anthropometric measurement for chair design is the popliteal height and buttock popliteal length. For someone seated, the popliteal height is the distance from the underside of the foot to the underside of the thigh at the knees. It is sometimes called the "stool height". The term "sitting height" is reserved for the height to the top of the head when seated.
|
|
For American men, the median popliteal height is and for American women it is . The popliteal height, after adjusting for heels, clothing and other issues, is used to determine the height of the chair seat. Mass-produced chairs are typically high. For someone seated, the buttock popliteal length is the horizontal distance from the back most part of the buttocks to the back of the lower leg.
|
|
Smaller arteries carry blood supply from the popliteal artery to the calf and into the foot. Blockages caused by plaque build-up or atherosclerosis in any of these arteries can reduce leg blood circulation, causing leg pain that may interfere with daily life. Standard Popliteal bypass surgery involves the bypass of the popliteal artery. During surgery, incisions are made depending on the location of the blockage.
|
|
Popliteal bypass surgery, more specifically known as femoral popliteal bypass surgery (FPB) or more generally as lower extremity bypass surgery, is a surgical procedure used to treat diseased leg arteries above or below the knee. It is used as a medical intervention to salvage limbs that are at risk of amputation and to improve walking ability in people with severe intermittent claudication (leg muscle pain) and ischemic rest pain. Popliteal bypass surgery is a common type of peripheral bypass surgery which carries blood from the femoral artery of the thigh to the end of the popliteal artery behind the knee. The femoral artery runs along the thigh and extends to become the popliteal artery which runs posteriorly to the knee joint and femur.
|
|
Anatomical abnormalities involving the medial head of gastrocnemius muscle result in popliteal artery entrapment syndrome.
|
|
Before its division, the common fibular nerve gives off several branches in the popliteal fossa.
|
|
A popliteal artery aneurysm is a bulging (aneurysm) of the popliteal artery. A PAA is diagnosed when a focal dilation greater than 50% of the normal vessel diameter is found (the normal diameter of a popliteal artery is 0.7-1.1 cm). PAAs are the most common aneurysm of peripheral vasculature, accounting for 85% of all cases. PAAs are bilateral in some 50% of cases, and are often (40-50%) associated with an abdominal aortic aneurysm.
|
|
464 The artery enters the thigh as the femoral artery which descends the medial side of the thigh to the adductor canal. The canal passes from the anterior to the posterior side of the limb where the artery leaves through the adductor hiatus and becomes the popliteal artery. On the back of the knee the popliteal artery runs through the popliteal fossa to the popliteal muscle where it divides into anterior and posterior tibial arteries. In the lower leg, the anterior tibial enters the extensor compartment near the upper border of the interosseus membrane to descend between the tibialis anterior and the extensor hallucis longus.
|
|
Van der Woude syndrome (VDWS) and popliteal pterygium syndrome (PPS) are allelic variants of the same condition; that is, they are caused by different mutations of the same gene. PPS includes all the features of VDWS, plus popliteal pterygium, syngnathia, distinct toe/nail abnormality, syndactyly, and genito-urinary malformations.
|
|
The symptoms of pseudothrombophlebitis include pain, swelling, erythema and tenderness. It most commonly, but not exclusively, affects the legs. The presence of a popliteal cyst makes this diagnosis more likely. However, the presence of a popliteal cyst does not rule out deep vein thrombosis and warrants further investigation.
|
|
For example, the top drawing on the right shows an oval fibrous type of adductor hiatus, and the bottom one shows a bridging muscular adductor hiatus. Four structures are associated with the adductor hiatus. However, only two structures enter and then leave through the hiatus; namely the femoral artery and femoral vein. Those vessels become the popliteal vessels (popliteal artery and popliteal vein) immediately after they leave the hiatus, where they form a network of anastomoses called the genicular vessels.
|
|
The popliteal fossa is to be examined bilaterally with the knee in a semi-flexed position. In some 60% of cases, the popliteal aneurysm presents as a palpable pulsatile mass at the level of the knee joint. Doppler ultrasonography is the preferred diagnostic method. CT and MR angiography may also be employed.
|
|
The lateral superior genicular artery is a branch of the popliteal artery that supplies a portion of the knee joint.
|
|
Arthrography and venography using imaging dyes allow for the detection of popliteal cysts and the exclusion of thrombotic lesions but are invasive procedures. Magnetic resonance imaging and computerised axial tomography scans allow for the detection of a ruptured or dissected popliteal cyst and, if in the same plane as the scan, the detection of a deep vein thrombosis.
|
|
The oblique popliteal ligament (posterior ligament) is a broad, flat, fibrous band, formed of fasciculi separated from one another by apertures for the passage of vessels and nerves. It is attached above to the upper margin of the intercondyloid fossa and posterior surface of the femur close to the articular margins of the condyles, and below to the posterior margin of the head of the tibia. Superficial to the main part of the ligament is a strong fasciculus, derived from the tendon of the semimembranosus and passing from the back part of the medial condyle of the tibia obliquely upward and laterally to the back part of the lateral condyle of the femur. The oblique popliteal ligament forms part of the floor of the popliteal fossa, and the popliteal artery rests upon it.
|
|
The small saphenous vein (SSV), runs along the posterior aspect of the leg as far as the popliteal region, in the upper calf. Here it enters the popliteal space which is located between the two heads of the gastrocnemius muscle where it usually drains above the knee joint in the popliteal vein or a little less often in the GSV or other deep muscular veins of the thigh. The use of ultrasonography has allowed a number of variations to be shown at this level; when no contact is made with the popliteal vein it might be seen to drain in the GSV, at a variable level; or, it may merge with the Giacomini vein and drain in the GSV at the superior 1/3 of the thigh. It can also but rarely, drain in the vein of the semimembranosus (thigh muscle) (shown below).
|
|
The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.
|
|
The arcuate popliteal ligament is an extracapsular ligament of the knee. It is Y-shaped and is attached to the posterior portion of the head of the fibula. From there it goes to its two insertions; the medial one goes over popliteus muscle and blends with the oblique popliteal ligament, the lateral one to the Lateral epicondyle of the femur and blends there with the lateral head of gastrocnemius muscle.
|
|
The muscle's vascular supply is derived from the anastomoses of several arteries: the perforating branches of the profunda femoris artery, the inferior gluteal artery, and the popliteal artery.
|
|
The femoral artery is susceptible to peripheral arterial disease. When it is blocked through atherosclerosis, percutaneous intervention with access from the opposite femoral may be needed. Endarterectomy, a surgical cut down and removal of the plaque of the femoral artery is also common. If the femoral artery has to be ligated surgically to treat a popliteal aneurysm, blood can still reach the popliteal artery distal to the ligation via the genicular anastomosis.
|
|
The muscle may arise from the oblique popliteal ligament. Interdigitations with the lateral head of the gastrocnemius and a fibrous extension of the muscle to the patella are not unusual.
|
|
In July 2018, Williams was revealed to have popliteal artery entrapment syndrome (PAES) in both legs. If it degenerates, the vascular disease could require a surgical procedure in the future.

Datkha could subordinate only to the Khan and help him to manage the Khanate. The mother of Mustafa was Bakty, she was intellectual in her own right and she was a descendant of the famous Batu Khan. Bakty was well- educated, owned Arabic and Persian languages. Mustafa Shokay was born on 25 December 1890, in Akmechet, (today Kyzyl-Orda), Kazakhstan. He was from the Middle Juz (horde) of the Kypchak’s tribe, Torgai clan, Shashty popliteal, Boshay knee, Zhanay popliteal.
|
|
The common fibular nerve (common peroneal nerve; external popliteal nerve; lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint. It divides at the knee into two terminal branches: the superficial fibular nerve and deep fibular nerve, which innervate the muscles of the lateral and anterior compartments of the leg respectively. When the common fibular nerve is damaged or compressed, foot drop can ensue.
|
|
People with peripheral artery disease undergoing popliteal bypass surgery are also more susceptible to myocardial infarction and abnormal heart rhythms, as patients requiring popliteal bypass are more likely to have higher cholesterol levels and higher blood pressure. The excess strain and damage caused by HBP and high cholesterol level can cause atherosclerosis. Over time, the coronary artery narrows and increases the patient's chance of getting a heart attack. Myocardial infarctions can also be caused by graft failure and hypoperfusion.
|
|
The popliteal fossa (sometimes referred to as the hough,[1] or kneepit in analogy to the armpit) is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia. Like other flexion surfaces of large joints (groin, armpit, cubital fossa and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased number of lymph nodes.
|
|
The arteries that supply the posterior compartment of the thigh arise from the inferior gluteal and the perforating branches of the profunda femoris artery, a major collateral branch of the femoral artery and part of the anterior compartment of thigh. The femoral artery itself crosses the adductor hiatus to enter the posterior compartment at the level of the popliteal fossa, giving branches that supply the knee. This crossing marks the point in which the vessel changes its name to popliteal artery.
|
|
The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris. It then winds around the neck of the fibula to pierce the fibularis longus and divides into terminal branches of superficial fibular nerve and deep fibular nerve.
|
|
It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh.
|
|
Rothenberg died November 3, 2006 following complications after surgery for a popliteal aneurysm, a weakened blood vessel in the leg. He lived with his partner, Dr. Carol Schneebaum. He had three sons, two stepdaughters and nine grandchildren.
|
|
Lincoln sign is the medical sign consisting of excessive popliteal artery pulsation due to hemodynamic effects of aortic regurgitation. This sign is associated with Marfan syndrome, in which aortic root dilation and aortic incompetence are common features.
|
|
The middle third of the posterior surface is divided by a vertical ridge into two parts; the ridge begins at the popliteal line and is well- marked above, but indistinct below; the medial and broader portion gives origin to the Flexor digitorum longus, the lateral and narrower to part of the Tibialis posterior. The remaining part of the posterior surface is smooth and covered by the Tibialis posterior, Flexor digitorum longus, and Flexor hallucis longus. Immediately below the popliteal line is the nutrient foramen, which is large and directed obliquely downward.
|
|
Since the operation involves multiple cuts being made on the leg, this relatively high risk surgery involves several risks. Some complications are common for all types of leg associated surgery, while some are specific to popliteal bypass surgery. Complications include but not limited to the following: In the study of 6,007 people carried out popliteal bypass surgery, the overall rate of morbidity and mortality was 36.8% and 2.3% respectively within 30 days post-surgery. However, there are variations in studies of mortality as one particular study did not find any person deaths.
|
|
The fibular veins are deep veins that help carry blood from the lateral compartment of the leg. They drain into the posterior tibial veins, which will in turn drain into the popliteal vein. The fibular veins accompany the fibular artery.
|
|
Popliteal aneurysms are rarely symptomatic; they are typically discovered during routine physical examinations. The cause of these aneurysms is unknown, but they are more common in older people and men and occur in both legs about 50% of the time.
|
|
Like other flexion surfaces of large joints (groin, popliteal fossa, cubital fossa and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes.
|
|
The inferior genicular arteries (inferior articular arteries), two in number, arise from the popliteal beneath the gastrocnemius. On the inside of the knee, is the medial inferior genicular artery, and on the outer side is the lateral inferior genicular artery.
|
|
The genicular anastomosis provides collateral circulation to supply the leg when the knee is fully flexed. When the knee suffers a popliteal aneurysm, if the femoral artery has to be ligated surgically, blood can still reach the popliteal artery distal to the ligation via the genicular anastomosis. However, if flow in the femoral artery of a normal leg is suddenly disrupted, blood flow distally is rarely sufficient. The reason for this is the fact that the genicular anastomosis is only present in a minority of individuals and is always undeveloped when disease in the femoral artery is absent.
|
|
The intermediate ridge or pectineal line is continued to the base of the lesser trochanter and gives attachment to the pectineus; the medial ridge is lost in the intertrochanteric line; between these two a portion of the iliacus is inserted. Below, the linea aspera is prolonged into two ridges, enclosing between them a triangular area, the popliteal surface, upon which the popliteal artery rests. Of these two ridges, the lateral is the more prominent, and descends to the summit of the lateral condyle. The medial is less marked, especially at its upper part, where it is crossed by the femoral artery.
|
|
Although antibiotics are generally given before and after surgery, people are still susceptible to wound infections and there is a 7.8% incidence of popliteal bypass surgery associated infections. Infection contraction is common in popliteal bypass surgery because of the poor blood circulation to the area, poor circulation means that the wounds will heal slower and the incision sites will have a higher chance of becoming infected. The infection of the vascular graft prosthesis occurs in every 1 in 500 people, under such circumstance the removal of the graft is needed. Graft infection is strongly associated with high morbidity and mortality.

|
According to HayashiHayashi in his Reader, 3rd ed., pg. 35ff, 2009 with this technique an exercise is presented with which all basic treatments are started practically. Palpating the popliteal fossa one can feal hardenings of the local tendons by moving one's fingers.
|
|
Tibial-fibular trunk (or tibial-peroneal trunk) is a segment of the artery below the knee, distal to the origin of the anterior tibial artery off the popliteal artery, and proximal to the branch point of the posterior tibial artery and the fibular artery.
|
|
Where pseudothrombophlebitis and thrombophlebitis present as differential diagnoses, DVT is excluded by the absence of a deep vein thrombosis, and the presence of a popliteal cyst is suggestive of pseudothrombophlebitis. The differentiation requires the use of radiological or arthroscopic imaging modalities. In this condition, imaging modalities often indicated include the use of Doppler and non-Doppler ultrasound, arthrography, venography magnetic resonance imaging (MRI) and computerised axial tomography (CAT scan). Ultrasound modalities in general are useful for the detection of a ruptured or dissecting popliteal cysts, while Doppler ultrasound has the additional benefit of detecting venous stenosis such as that caused by deep vein thrombosis.
|
|
From the mid calf down to the ankle the nerve courses close to the skin along a line drawn from the mid-posterior popliteal fossa to just posterior to the lateral malleolus and then under the malleolus and forward along the lateral aspect of the foot.
|
|
CT angiogram 3D reconstruction, posterior view showing a normal artery on the left, and occlusion to right popliteal artery as a result of a knee dislocation Symptoms include knee pain. The joint may also be obviously out of place. A joint effusion is not always present.
|
|
Other potential causes include stress fractures, compartment syndrome, nerve entrapment, and popliteal artery entrapment syndrome. If the cause is unclear, medical imaging such as a bone scan or magnetic resonance imaging (MRI) may be performed. Bone scans and MRI can differentiate between stress fractures and shin splints.
|
|
The posterior tibial artery of the lower limb carries blood to the posterior compartment of the leg and plantar surface of the foot, from the popliteal artery via the tibial-fibular trunk. It is accompanied by a deep vein, the posterior tibial vein, along its course.
|
|
The two anterior tibial veins ascend in the interosseous membrane between the tibia and fibula and unite with the posterior tibial veins to form the popliteal vein. Like most deep veins in legs, anterior tibial veins are accompanied by the homonym artery, the anterior tibial artery, along its course.
|
|
Fracture at the supracondylar area of femur, where the adductor part of the adductor magnus attaches, will most likely cause damage to the femoral artery and may cause impairment of the blood supply to the lower leg. Popliteal artery can also be damaged by the fracture of distal femur.
|
|
Over time, there is a decreasing trend of percentage patency (likelihood a vessel will remain open) in popliteal bypass surgery, 88% in the first year, 79% and 76% at 3 and 5 years respectively. Environmental conditions and overall patient health may also affect the patency of the graft.
|
|
It is performed slightly inferior to the inguinal ligament, and the nerve is under the fascia iliaca. The sciatic nerve block is done for surgeries at or below the knee. The nerve is located in the gluteus maximus muscle. The popliteal block is done for ankle, achilles tendon, and foot surgery.
|
|
The fibular artery typically arises from the posterior tibial artery. Therefore, the posterior tibial artery proximal to the fibular artery origin is sometimes called the tibial-peroneal trunk or tibial-fibular trunk and it could be said that the popliteal artery bifurcates into the tibial-fibular trunk and anterior tibial artery.
|
|
An opportunity presented itself when a man was brought in with a dislocated knee and damaged popliteal artery. Welch performed an artery graft and the leg immediately regained life.Welch, p. 160. As a surgeon, not only did Welch perform remarkable surgeries, but he had the opportunity to work on remarkable individuals.
|
|
A Baker's cyst, also known as a popliteal cyst, is a type of fluid collection behind the knee. Often there are no symptoms. If symptoms do occur these may include swelling and pain behind the knee, or knee stiffness. If the cyst breaks open, pain may significantly increase with swelling of the calf.
|
|
Rates of restenosis differ between devices (e.g., stent-grafts, balloon angioplasty, etc.) and location of procedure (i.e., centrally located in the heart, such as the coronary artery, or in peripheral vessels such as the popliteal artery in the leg, the pudendal artery in the pelvis, or the carotid artery in the neck).
|
|
Arteriosclerosis obliterans is an occlusive arterial disease most prominently affecting the abdominal aorta and the small- and medium-sized arteries of the lower extremities, which may lead to absent dorsalis pedis, posterior tibial, and/or popliteal artery pulses. It is characterized by fibrosis of the tunica intima and calcification of the tunica media.
|
|
It is inserted mainly into the horizontal groove on the posterior medial aspect of the medial condyle of the tibia. The semimembranosus is wider, flatter, and deeper than the semitendinosus (with which it shares very close insertion and attachment points). The tendon of insertion gives off certain fibrous expansions: one, of considerable size, passes upward and laterally to be inserted into the posterior lateral condyle of the femur, forming part of the oblique popliteal ligament of the knee- joint; a second is continued downward to the fascia which covers the popliteus muscle; while a few fibers join the medial collateral ligament of the joint and the fascia of the leg. The muscle overlaps the upper part of the popliteal vessels.
|
|
The anterior tibial artery of the leg carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery. It is accompanied by the anterior tibial vein, along its course. It crosses the anterior aspect of the ankle joint, at which point it becomes the dorsalis pedis artery.
|
|
For someone seated, the popliteal height is the distance from the underside of the foot to the underside of the thigh at the knees. It is sometimes called the "stool height". (The term "sitting height" is reserved for the height to the top of the head when seated.). This height greatly varies between ethnic groups.
|
|
When there is a GSV thrombosis or other cause of insufficiency, the Giacomini vein can divert the blood flow to the SSV and from there to the popliteal vein. Where surgery, other than stripping or laser ablation is intended, the examiner will make reference to the blood flow direction in this vein, as it will be of importance.
|
|
At the insertion of the muscle, there is a series of osseoaponeurotic openings, formed by tendinous arches attached to the bone. The upper four openings are small, and give passage to the perforating branches of the profunda femoris artery. The lowest (often referred to as the adductor hiatus) is large, and transmits the femoral vessels to the popliteal fossa.
|
|
Inoculation eschar on popliteal area and discrete maculopapular elements in patient with lymphangitis infected with Rickettsia sibirica mongolitimonae Rickettsia sibirica is a species of Rickettsia. This bacterium is the etiologic agent of North Asian tick typhus, which is also known as Siberian tick typhus. The ticks that transmit it are primarily various species of Dermacentor and Haemaphysalis.
|
|
The hamstrings are innervated by the sciatic nerve, specifically by a main branch of it: the tibial nerve. (The short head of the biceps femoris is innervated by the common fibular nerve). The sciatic nerve runs along the longitudinal axis of the compartment, giving the cited terminal branches close to the superior angle of the popliteal fossa.
|
|
On the first day of battle, Johnston personally led the attack on the enemy. He was a victim of friendly fire, receiving a hit in the knee which severed his popliteal artery. Johnston died within an hour. His death resulted in critical reassignments of his command to less talented generals who failed to repair the virtually doomed Western Theater.
|
|
Although both conditions feature a cleft lip/palate, syngnathia, and popliteal pterygium, they are clinically distinguishable from the autosomal dominant case. Lethal PPS is differentiated by microcephaly, corneal aplasia, ectropion, bony fusions, hypoplastic nose and absent thumbs, while PPS with Ectodermal Dysplasia is differentiated by woolly hair, brittle nails, ectodermal anomalies, and fissure of the sacral vertebrae.
|
|
The incidence of early graft thrombosis is between 5-15% for popliteal bypass surgery. The cause of thrombosis is commonly due to technical errors of the surgery, other causes may include stenosis, narrow vein grafts, a low cardiac output and the compression of the graft. In such cases, heparin (anticoagulant) and thrombectomy can be used to treat graft thrombosis.
|
|
The superior genicular arteries (superior articular arteries), two in number, arise one on either side of the popliteal artery, and wind around the femur immediately above its condyles to the front of the knee-joint. The medial superior genicular artery is on the inside of the knee and the lateral superior genicular artery is on the outside.
|
|
The Pratt Test is a simple test to check for deep vein thrombosis in the leg. It involves having the patient lie supine with the leg bent at the knee, grasping the calf with both hands and pressing on the popliteal vein in the proximal calf. If the patient feels pain, it is a sign that a deep vein thrombosis exists.
|
|
Initial physical examination was remarkable only for mildly pale conjunctivae and mild abdominal tenderness and pain in the left popliteal fossa. A complete blood count and complete metabolic panel were normal. Prothrombin time (PT) was above 100 s, partial thromboplastin time (PTT) was above 200 s and international normalized ratio (INR) was reported as above 12.0. Urinalysis revealed hematuria (blood in the urine).
|
|
The anterior tibial vein is a vein in the lower leg. In human anatomy, there are anterior two tibial veins. They originate and receive blood from the dorsal venous arch, on the back of the foot and empties into the popliteal vein. The anterior tibial veins drain the ankle joint, knee joint, tibiofibular joint, and the anterior portion of the lower leg.
|
|
His reputation as a surgeon attracted patients from all over Europe to Pisa, including the Irish aristocrat Margaret King, who had to dress as a man to gain admission to the lectures. Berlinghieri was a close friend of anatomist Paolo Mascagni (1752–1815). Berlinghieri was the first surgeon in Italy to perform Hunter's procedure for aneurysms of the popliteal fossa.
|
|
Like other flexion surfaces of large joints (popliteal fossa, armpit, cubital fossa and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes. In a venography procedure, the groin is the preferred site for incisions to enter a catheter into the vascular system.
|
|
In human anatomy, the adductor hiatus also known as hiatus magnus is a hiatus (gap) between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa. It is the termination of the adductor canal and lies about 8–13.5 cm. superior to the adductor tubercle.
|
|
It has become the reference standard for examining the condition and hemodynamics of the lower limb veins. Particular veins of the deep venous system (DVS), and the superficial venous system (SVS) are looked at. The great saphenous vein (GSV), and the small saphenous vein (SSV) are superficial veins which drain into respectively, the common femoral vein and the popliteal vein. These veins are deep veins.
|
|
They are posterior to the medial femoral condyle. The synovial sac of the knee joint can, under certain circumstances, produce a posterior bulge, into the popliteal space, the space behind the knee. When this bulge becomes large enough, it becomes palpable and cystic. Most Baker's cysts maintain this direct communication with the synovial cavity of the knee, but sometimes, the new cyst pinches off.

|
Easy chairs for watching television or movies are somewhere in between depending on the height of the screen. Ergonomic design distributes the weight of the occupant to various parts of the body. A seat that is higher results in dangling feet and increased pressure on the underside of the knees ("popliteal fold"). It may also result in no weight on the feet which means more weight elsewhere.
|
|
Venous Doppler ultrasound of lower extremities demonstrated left popliteal vein thrombosis. Computed tomography scan of the abdomen demonstrated transmural hematoma, and a fecal occult blood test was positive. A full anticoagulant work-up showed critical reduction of vitamin K-dependent factors II, VII, IX, and X. PT and PTT corrected with mixing studies proving factor deficiency as the cause of the coagulopathy. Lupus anticoagulant studies were negative.
|
|
Posteriorly, the gluteal region corresponds to the gluteus maximus. The anterior region of the thigh extends distally from the femoral triangle to the region of the knee and laterally to the tensor fasciae latae. The posterior region ends distally before the popliteal fossa. The anterior and posterior regions of the knee extend from the proximal regions down to the level of the tuberosity of the tibia.

The deep fascia of leg, or crural fascia forms a complete investment to the muscles, and is fused with the periosteum over the subcutaneous surfaces of the bones. The deep fascia of the leg is continuous above with the fascia lata, and is attached around the knee to the patella, the patellar ligament, the tuberosity and condyles of the tibia, and the head of the fibula. Behind, it forms the popliteal fascia, covering in the popliteal fossa; here it is strengthened by transverse fibers, and perforated by the small saphenous vein. It receives an expansion from the tendon of the biceps femoris laterally, and from the tendons of the sartorius, gracilis, semitendinosus, and semimembranosus medially; in front, it blends with the periosteum covering the subcutaneous surface of the tibia, and with that covering the head and malleolus of the fibula; below, it is continuous with the transverse crural and laciniate ligaments.

EMCS appears clinically as a slowly developing mass of soft tissue associated with pain and tenderness. Two-thirds of EMC tumors are primarily found in sub-fascia soft tissues of the proximal extremities and limb girdles, especially the thigh and popliteal fossa. The average tumor size is about 9.3 cm (3.3–18 cm). Uncommon locations are the distal extremities, the paraspinal part and the head and neck region.

Doppler ultrasonography showing absence of flow and hyperechogenic content in deep vein thrombosis of the subsartorial vein. Coronal plane, seen from medial side of lower leg, showing thrombosis of the fibular veins, with hyperechoic content and only marginal blood flow. Ultrasonography in suspected deep vein thrombosis focuses primarily on the femoral vein and the popliteal vein, because thrombi in these veins are associated with the greatest risk of harmful pulmonary embolism.

The anterior tibial recurrent artery is a small artery in the leg. It arises from the anterior tibial artery, as soon as that vessel has passed through the interosseous space. It ascends in the tibialis anterior muscle, ramifies on the front and sides of the knee-joint, and assists in the formation of the patellar plexus by anastomosing with the genicular branches of the popliteal, and with the highest genicular artery.

His first career touchdown reception came in the second quarter as Shaheen was left wide open on a blown coverage by the Steelers. Throughout the first seven regular season games, Shaheen was predominantly used as a blocking tight end in two and three tight end sets. During a Week 8 matchup against the New Orleans Saints, starting tight end Zach Miller suffered a dislocated knee and tore his popliteal artery.

It is done above the knee on the posterior leg where the sciatic nerve starts splitting into the common peroneal and tibial nerves. The saphenous nerve block is often done in combination with the popliteal block for surgeries below the knee. The saphenous nerve is numbed at the medial part of the lower thigh under the sartorius muscle. The lumbar plexus block is an advanced technique indicated for hip, anterior thigh, and knee surgery.

The inability to compress the vein is one of the more reliable indications of venous thrombosis. There is a simplified technique called "compression ultrasonography" which can be used for quick DVT diagnosis, mainly for the common femoral vein and the popliteal vein. It is very useful in an emergency situation and is performed just by vein compression using transducer pressure. Compression ultrasonography has both high sensitivity and specificity for detecting DVT in symptomatic patients.

The nerve then runs straight down the back of the leg, through the popliteal fossa to supply the ankle flexors on the back of the lower leg and then continues down to supply all the muscles in the sole of the foot.Thieme Atlas of Anatomy (2006), pp. 480–81 The pudendal (S2-S4) and coccygeal nerves (S5-Co2) supply the muscles of the pelvic floor and the surrounding skin.Thieme Atlas of Anatomy (2006), pp.

500px DVT often develops in the calf veins and "grows" in the direction of venous flow, towards the heart. When DVT does not grow, it can be cleared naturally and dissolved into the blood (fibrinolysis). Veins in the leg or pelvis are most commonly affected, including the popliteal vein (behind the knee), femoral vein (of the thigh), and iliac veins of the pelvis. Extensive lower-extremity DVT can even reach into the inferior vena cava (in the abdomen).

Other common places are the brachial artery, radial artery, popliteal artery, dorsalis pedis, and others. There are four types of atherectomy devices: orbital, rotational, laser, and directional. The decision to use which type of device is made by the interventionist, based on a number of factors. They include the type of lesion being treated, the physician's experience with each device, and interpretation of the devices' risks and effectiveness, based on a review of the medical literature.

Cases of brodifacoum intoxication have been reported in the human medical literature. In one report, a woman deliberately consumed over 1.5 kg of rat bait, constituting about 75 mg brodifacoum, but made a full recovery after receiving conventional medical treatment. In another case reported in 2013, a 48-year-old female patient reported 4 days of mild dyspnea, dry cough, bilateral popliteal fossae pain, and diffuse upper abdominal pain. She had no history of liver disease or alcohol or illicit substance abuse.

A sample of blood being taken from the median cubital vein via the cubital fossa with a vacutainer for a blood test. Like other flexion surfaces of large joints (groin, popliteal fossa, armpit and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes. During blood pressure measurements, the stethoscope is placed over the brachial artery in the cubital fossa. The artery runs medial to the biceps tendon.
|
|
Although the lateral collateral ligament (LCL) passes in close proximity, the lateral meniscus has no attachment to this structure. The joint capsule attaches to the entire periphery of each meniscus but adheres more firmly to the medial meniscus. An interruption in the attachment of the joint capsule to the lateral meniscus, forming the popliteal hiatus, allows the popliteus tendon to pass through to its femoral attachment site. Contraction by the popliteus during knee flexion pulls the lateral meniscus posteriorly, avoiding entrapment within the joint space.
|
|
As the tibial nerve travels down the popliteal fossa, and before it goes beneath the gastrocnemius, it gives off a cutaneous branch which is the medial sural cutaneous nerve. This nerve courses laterally over the lateral head of the gastrocnemius. The common fibular nerve also gives off a small cutaneous branch which is the lateral sural cutaneous nerve. When the common fibular nerve is divided from the sciatic nerve, it travels parallel to the distal portion of the biceps femoris muscle and towards the fibular head.

In anatomy, there are two posterior tibial veins of the lower limb. They receive blood from the medial and lateral plantar veins and drain the posterior compartment of the leg and the plantar surface of the foot to the popliteal vein which it forms when it joins with the anterior tibial vein. Like most deep veins, posterior tibial veins are accompanied by an homonym artery, the posterior tibial artery, along its course. They receive the most important perforator veins: the Cockett perforators, superior, medial and inferior.

Pseudothrombophlebitis syndrome is a clinical condition where there are signs and symptoms of phlebitis in the absence of a thrombophlebitis lesion. Symptoms include pain, swelling, erythema and tenderness evolving over hours or days. It is often associated with the rupture or dissection of a popliteal cyst otherwise known as a Baker's cyst,1\. Munk, Peter L Lee, Mark J. Ruptured Baker's cyst producing a pseudothrombophlebitis syndrome Canadian Journal of Surgery Aug 2000 43(4) 255 although it can be associated with other disorders such as the arthritides.

Victims are typically shot in the knees, ankles, thighs, elbows, ankles, or a combination of the above. Kneecapping is considered a "trademark" of the IRA, although it became less popular over time because the disability and mortality incurred was unpopular with the community. It was replaced with low-velocity shots aimed at the soft tissue in the lower limbs. As a result, "kneecapping" is frequently a misnomer because by the 2010s most injuries targeted the femur or popliteal area rather than the knee joint.
|
|
The kneecap is the patella and patellar while the back of the knee is the popliteus and popliteal area. The leg (between the knee and the ankle) is the crus and crural area, the lateral aspect of the leg is the peroneal area, and the calf is the sura and sural region. The ankle is the tarsus and tarsal, and the heel is the calcaneus or calcaneal. The foot is the pes and pedal region, and the sole of the foot the planta and plantar.

Although the Bears turned the ball over on downs, they had another chance after Lutz's 49-yard field goal put them behind by eight points. However, Trubisky's pass for Tre McBride was intercepted by Marshon Lattimore to seal the loss. Miller was taken to the University Medical Center New Orleans for treatment. In addition to a dislocated knee, Miller was revealed to have torn the popliteal artery in his region, an injury that is common in car accidents and raised the possibility of amputation.

A sensitive rugby player-cum-writer for a small magazine grows a vagina behind his knee. His megalomaniacal general practitioner, having discovered the vagina during an examination, conceals it from Bull, telling him it was 'a burn and a wound', though later visits Bull at home, fixated on this popliteal yoni. The doctor, removing the bandages from the site, reveals the truth, and seduces Bull while he is traumatised and huddled beneath the sink. Gender stereotypes are examined; much fun is made of modern literary criticism and its often clichéd takes on the gender debate.

Qualitative comparison has been performed by three vascular surgeons and three interventional radiologists, with about 17 years of experience on the average. In an online visual questionnaire, which showed DVA and DSA image pairs of the same anatomical regions, raters were asked to choose the image which they found to be more useful for making the diagnosis. Overall, the raters judged the kinetic images better in 69 % of all images. Regarding different anatomical regions, the raters agreed that the DVA was significantly better for talocrural and popliteal regions.

Illustrations of the genicular anastomosis in textbooks all appear to have been derived from the idealized image, shown in the sidebox, produced first by Gray's Anatomy in 1910. Neither the 1910 illustration, nor any subsequent version, was made of an anatomical dissection but rather from the writings of John Hunter (surgeon) and Astley Cooper which described the genicular anastomosis many years after ligation of the femoral artery for popliteal aneurysm. The genicular anastomosis has not been demonstrated even with modern imaging techniques such as X-ray computed tomography or angiography.

PAAs are most often asymptomatic. Chronic symptoms are most often secondary to the mass effect exerted upon adjoining structures by the aneurysm (e.g. pain and paresthesias due to tibial nerve compression, calf swelling due to compression of the popliteal vein). Thrombosis within the aneurysm and subsequent luminal narrowing may result in claudication of gradual onset, while an acute thrombosis (occluding the vessel at the side of the aneurysm or lodging distally as the vessel narrows) may lead to acute lower extremity ischaemia and associated symptomatology (pain, paresthesia, paresis, pallor, poikilothermia).

On October 29, 2017, in the Bears' Week 8 game against the New Orleans Saints, Miller landed on his left knee while attempting to catch a touchdown pass, dislocating it. The score was initially ruled a touchdown before being overturned. He was taken to nearby University Medical Center New Orleans where further examination revealed he not only dislocated his left knee, but also tore his popliteal artery, a serious, career-threatening injury that raised the possibility of amputation. Miller underwent successful vascular surgery that day and remained hospitalized for three weeks.

DVT in the legs is proximal when above the knee and distal (or calf) when below the knee. DVT below the popliteal vein, a proximal vein behind the knee, is classified as distal and has limited clinical significance compared to proximal DVT. Iliofemoral DVT has been described as involving either the iliac or common femoral vein; elsewhere, it has been defined as involving at a minimum the common iliac vein, which is near the top of the pelvis. Upper extremity DVT occurs in the arms or the base of the neck.

"None of that, sir," Johnston roared at the officer, "we are not here for plunder." Then, realizing he had embarrassed the man, he picked up a tin cup off a table and announced, "Let this be my share of the spoils today," before directing his army onward. At about 2:30 pm, while leading one of those charges against a Union camp near the "Peach Orchard," he was wounded, taking a bullet behind his right knee. The bullet clipped a part of his popliteal artery and his boot was filling up with blood.

The pulse is commonly taken at the wrist (radial artery). Alternative sites include the elbow (brachial artery), the neck (carotid artery), behind the knee (popliteal artery), or in the foot (dorsalis pedis or posterior tibial arteries). The pulse is taken with the index finger and middle finger by pushing with firm yet gentle pressure at the locations described above, and counting the beats felt per 60 seconds (or per 30 seconds and multiplying by two). The pulse rate can also be measured by listening directly to the heartbeat using a stethoscope.

The arterial supply is by the femoral artery and the obturator artery. The lymphatic drainage closely follows the arterial supply and drains to the lumbar lymphatic trunks on the corresponding side, which in turn drains to the cisterna chyli. The deep venous system of the thigh consists of the femoral vein, the proximal part of the popliteal vein, and various smaller vessels; these are the site of proximal deep venous thrombosis. The venae perfortantes connect the deep and the superficial system, which consists of the saphenous veins (the site of varicose veins).

In 1999, he was the first surgeon in the world to perform a femoral- popliteal bypass using only laparoscopic techniques. His other work includes appendectomies; hernia repairs; removal of lipomas and haemorrhoids; and treatment of varicose veins using ligation or sclerotherapy. He began working in disaster and war zones in 1993, when he saw footage of the war in Sarajevo. He has worked in disaster and war zones for several weeks each year since then, working as a volunteer surgeon for agencies such as Médecins Sans Frontières and the Red Cross.

Long periods of inactivity in a limited amount of space may be a reason for the increased risk of blood clot formation. In addition, bent knees compresses the vein behind the knee (the popliteal vein) and the low humidity, low oxygen, high cabin pressure and consumption of alcohol concentrate the blood. A recent study, published in the British Journal of Haematology in 2014, determined which groups of people, are most at risk for developing a clot during or after a long flight. The study focused on 8755 frequent flying employees from international companies and organizations.

It has two divisions, anterior and posterior, and acts to stabilize the knee during external rotation. The mid-third lateral capsular ligament is made of a part of the lateral capsule as it thickens and extends along the femur, attaching just anterior to the popliteus attachment at the lateral epicondyle, and extends distally to the tibia attaching slightly posterior to Gerdy's tubercle and anterior to the popliteal hiatus. In addition, it has a capsular attachment at the lateral meniscus. It has two divisions, the meniscofemoral component and the meniscotibial component named for the areas they span, respectively.

The posterior surface of the tibia presents, at its upper part, a prominent ridge, the soleal line (popliteal line in older texts), which extends obliquely downward from the back part of the articular facet for the fibula to the medial border, at the junction of its upper and middle thirds. It marks the lower limit of the insertion of the Popliteus, serves for the attachment of the fascia covering this muscle, and gives origin to part of the Soleus, Flexor digitorum longus, and Tibialis posterior muscles. The triangular area, above this line, gives insertion to the Popliteus.

Seat-edge pressure from the seat on an airplane on the popliteal area may contribute to vessel wall damage as well as venous stasis. Coagulation activation may result from an interaction between cabin conditions (such as hypobaric hypoxia) and individual risk factors for the formation of blood clots. Studies of the pathophysiologic mechanisms for the increased risk of Venous thrombosis embolism or VTE after long-distance travel have not produced consistent results, but venous stasis appears to play a major role; other factors specific to air travel may increase coagulation activation, particularly in passengers with individual risk factors for VTE.

Anatomists divide the lower limb into the thigh (the part of the limb between the hip and the knee) and the leg (which refers only to the area of the limb between the knee and the ankle). The thigh is the femur and the femoral region. The kneecap is the patella and patellar while the back of the knee is the popliteus and popliteal area. The leg (between the knee and the ankle) is the crus and crural area, the lateral aspect of the leg is the peroneal area, and the calf is the sura and sural region.

A mutation of the IRF6 gene can lead to the autosomal dominant van der Woude syndrome (VWS) or the related popliteal pterygium syndrome (PPS). Van der Woude syndrome can include cleft lip and palate features along with dental anomalies and lip fistulas. In addition, common alleles in IRF6 have also been associated with non-syndromic cases of cleft lip and/or palate through genome-wide association studies and in many candidate gene studies. These disorders are caused by mutations in the IRF6 gene and some of the phenotypic heterogeneity is due to different types of IRF6 mutations.

The fabella sign is displacement of the fabella that is seen in cases of synovial effusion and popliteal fossa masses. The fabella is an accessory ossicle located inside the gastrocnemius lateral head tendon on the posterior side of the knee, in about 25% of people. It can thus serve as a surrogate radio-opaque marker of the posterior border of the knee's synovium. On a lateral radiograph of the knee, an increase in the distance from the fabella to the femur or to the tibia can be suggestive of fluid or of a mass within the synovial fossa.

A synthetic graft remains open in 33 to 50 out of 100 people 5 years after Popliteal bypass surgery was carried out, whereas using veins, the bypass remains unobstructed in 66 out of 100 people. Moreover, the particular vein, great saphenous vein was shown to be more durable over the years after surgery. Also, when comparing the efficacy of using PTFE or the great saphenous vein in people with claudication and critical limb ischemia, the latter showed better long term results. A second bypass may be required if a blockage forms in the bypass graft later on.

The sural nerve is a sensory nerve in the calf region (sura) of the leg. It is made up of branches of the tibial nerve and common fibular nerve, the medial cutaneous branch from the tibial nerve, and the lateral cutaneous branch from the common fibular nerve. Once formed, the nerves runs down the mid calf to the ankle and along the skin from the mid-posterior popliteal fossa to just behind to the lateral malleolus and then under the malleolus and forward along the lateral aspect of the foot. The sural nerve supplies sensation to the skin of the lateral foot and lateral lower ankle.

The primary reason Wood gave for changing her findings was her realization that the microscopic slides of the popliteal vein and the photographs of muscle tissue in the surrounding area provided evidence of trauma which could explain the thrombus formation. She could not explain why she had not seen this before. Crow was highly critical of Wood in his memo stating: Crow also mentioned a unique set of circumstances that put Wood under tremendous pressure and might have affected the quality of her judgment. These being: # Wood's appearance on Inside Edition left her more vulnerable to litigation and committed her to a forensic position that would make any modification professionally embarrassing.

Darren T Beiko, Aspiration and Sclerotherapy versus hydrocelectomy for treatment of hydroceles, Urology Vol 61, Issue 4 (Apr 2003) Sclerotherapy is one method (along with surgery, radiofrequency and laser ablation) for the treatment of spider veins, occasionally varicose veins, and venous malformations. In ultrasound-guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection. Sclerotherapy often takes place under ultrasound guidance after venous abnormalities have been diagnosed with duplex ultrasound. Sclerotherapy under ultrasound guidance and using microfoam sclerosants has been shown to be effective in controlling reflux from the sapheno-femoral and sapheno-popliteal junctions.

With surgery operations such as popliteal bypass, there will be an increased probability of blood clot formation. In rare cases, a part of the clot in the leg breaks free and travels to the lungs, this is also known as a pulmonary embolism. A blockage in the blood vessels of the lung can be formed by pulmonary embolism, and this could cause excess fluid build-up in the lung. This condition is also known as pulmonary edema, which is the excess fluid present in the lungs, more specifically, the accumulation of excess fluid in the air sacs of the lung, leading to the impairment of gas exchange and potentially respiratory failure.

The medial superior genicular, a branch of the popliteal artery, runs in front of the Semimembranosus and Semitendinosus, above the medial head of the Gastrocnemius, and passes beneath the tendon of the Adductor magnus. It divides into two branches, one of which supplies the vastus medialis, anastomosing with the highest genicular and medial inferior genicular arteries; the other ramifies close to the surface of the femur, supplying it and the knee-joint, and anastomosing with the lateral superior genicular artery. The medial superior genicular artery is frequently of small size, a condition, which is associated with an increase in the size of the highest genicular.

The sural cutaneous nerve consists of the fusion of the medial sural cutaneous nerve (MSCN) which is a terminal branch of the tibial nerve and the lateral sural cutaneous nerve (LSCN) which is one of the terminal branches of the common fibular nerve. These two branches, MSCN and LSCN, are connected by the sural communicating branch and form the sural nerve. How the two branches fuse, the contribution of the fibular and tibial branch, the location of the connection, and differences between the two lower extremities contribute to variability of this nerve. The tibial nerve and the common fibular nerve arise as the sciatic nerve divides into two branches in the popliteal fossa.

Pringle was the first surgeon in Britain to carry out a free vein graft. He did this using a saphenous vein graft to restore continuity after excision of a syphilitic aneurysm of the popliteal artery and characteristically in this paper he duly acknowledged the "splendid work of Carrel". Alexis Carrel had been the first surgeon to make an arterial anastomosis, work which led to his being awarded the Nobel Prize in Physiology or Medicine in 1912. The technical quality of Pringle's operative technique is demonstrated by the fact that in this pioneering operation "not one drop of blood escaped at either of the lines of suture and distal pulses were instantly restored".

The absence of these teeth might play a role in the constricting of the dental arches. The clinical signs seen in VWS are similar to those of popliteal pterygium syndrome (PPS), which is also an autosomal dominant disease. Approximately 46% of affected individuals have lip pits; other features include genital abnormalities, abnormal skin near nails, syndactyly of fingers and toes, and webbed skin. The disease is also caused by mutations in IRF6; however, they occur in the DNA-binding domain of IRF6 and result in a dominant negative effect in which the mutated IRF6 transcription factor interferes with the ability of the wild type copy to function, in the case of a heterozygous individual.

The origin of the small saphenous vein, (SSV) is where the dorsal vein from the fifth digit (smallest toe) merges with the dorsal venous arch of the foot, which attaches to the great saphenous vein (GSV). It is a superficial vein being subcutaneous, (just under the skin). From its origin, it courses around the lateral aspect of the foot (inferior and posterior to the lateral malleolus) and runs along the posterior aspect of the leg (with the sural nerve), where it passes between the heads of the gastrocnemius muscle. This vein presents a number of different draining points: Usually it drains into the popliteal vein, at or above the level of the knee joint.

On 26 February 2015, Vila was doing gymnastics practice at the 2015 European Acrobatic Gymnastics Championships and broke her right tibia and fibula and compressing her popliteal artery which resulted in her right leg amputated above the knee and was forced to quit the sport after only being a professional acrobatic gymnast for three years prior to her injury. Her family filed a lawsuit for medical negligence against the doctor and the hospital where Vila was treated, the doctor was sentenced to two years in prison and received a four-year suspension, the family were given a €2 million compensation. However, in 2019, the doctor's jail sentence and suspension were revoked and the compensation was reduced.

A Health Technology Assessment found that sclerotherapy provided less benefit than surgery, but is likely to provide a small benefit in varicose veins without reflux from the sapheno-femoral or sapheno-popliteal junctions. It did not study the relative benefits of surgery and sclerotherapy in varicose veins with junctional reflux. This Health Technology Assessment monograph includes reviews of the epidemiology, assessment, and treatment of varicose veins, as well as a study on clinical and cost effectiveness of surgery and sclerotherapy The European Consensus Meeting on Foam Sclerotherapy in 2003 concluded that "Foam sclerotherapy allows a skilled practitioner to treat larger veins including saphenous trunks". A second European Consensus Meeting on Foam Sclerotherapy in 2006 has now been published.

In medicine, a pulse represents the tactile arterial palpation of the cardiac cycle (heartbeat) by trained fingertips. The pulse may be palpated in any place that allows an artery to be compressed near the surface of the body, such as at the neck (carotid artery), wrist (radial artery), at the groin (femoral artery), behind the knee (popliteal artery), near the ankle joint (posterior tibial artery), and on foot (dorsalis pedis artery). Pulse (or the count of arterial pulse per minute) is equivalent to measuring the heart rate. The heart rate can also be measured by listening to the heart beat by auscultation, traditionally using a stethoscope and counting it for a minute.

Another study in India found the vein to be present in 92% of those examined. It is located under the superficial fascia and its insufficiency seemed of little importance in the majority of patients with varicose disease, but the use of ultrasonography has highlighted a new significance of this vein. It can be part of a draining variant of the SSV which continues on to reach the GSV at the proximal third of the thigh instead of draining into the popliteal vein. The direction of its flow is usually anterograde (the physiological direction) but it can be retrograde when this vein acts as a bypass from an insufficient GSV to SSV to call on this last one to collaborate in draining.

A Samoan woman with malu Malu is a word in the Samoan language for a female- specific tattoo of cultural significance. The malu covers the legs from just below the knee to the upper thighs just below the buttocks, and is typically finer and delicate in design compared to the Pe'a, the equivalent tattoo for males. The malu takes its name from a particular motif of the same name, usually tattooed in the popliteal fossa (sometimes referred to as the kneepit, or poplit) behind the knee. It is one of the key motifs not seen on men. According to Samoan scholar Albert Wendt and tattooist Su'a Suluape Paulo II, in tattooing the term ‘malu’ refers to notions of sheltering and protection.

The two superficial depots are the paired inguinal depots, which are found anterior to the upper segment of the hind limbs (underneath the skin) and the subscapular depots, paired medial mixtures of brown adipose tissue adjacent to regions of white adipose tissue, which are found under the skin between the dorsal crests of the scapulae. The layer of brown adipose tissue in this depot is often covered by a "frosting" of white adipose tissue; sometimes these two types of fat (brown and white) are hard to distinguish. The inguinal depots enclose the inguinal group of lymph nodes. Minor depots include the pericardial, which surrounds the heart, and the paired popliteal depots, between the major muscles behind the knees, each containing one large lymph node.

Distal to the superior and extensor retinacula of the foot it becomes the dorsal artery of the foot. The posterior tibial forms a direct continuation of the popliteal artery which enters the flexor compartment of the lower leg to descend behind the medial malleolus where it divides into the medial and lateral plantar arteries, of which the posterior branch gives rise to the fibular artery. For practical reasons the lower limb is subdivided into somewhat arbitrary regions:Platzer (2004), p. 412 The regions of the hip are all located in the thigh: anteriorly, the subinguinal region is bounded by the inguinal ligament, the sartorius, and the pectineus and forms part of the femoral triangle which extends distally to the adductor longus.

Cheney's long histories of cardiovascular disease and periodic need for urgent health care raised questions of whether he was medically fit to serve in public office. Having smoked approximately 3 packs of cigarettes per day for nearly 20 years, Cheney had his first of five heart attacks on 18 June 1978, at age 37. Subsequent attacks in 1984, 1988, on 22 November 2000 and on 22 February 2010 resulted in moderate contractile dysfunction of his left ventricle. He underwent four-vessel coronary artery bypass grafting in 1988, coronary artery stenting in November 2000, urgent coronary balloon angioplasty in March 2001, and the implantation of a cardioverter-defibrillator in June 2001. On September 24, 2005, Cheney underwent a six-hour endo-vascular procedure to repair popliteal artery aneurysms bilaterally, a catheter treatment technique used in the artery behind each knee.

The semitendinosus, remarkable for the great length of its tendon of insertion, is situated at the posterior and medial aspect of the thigh. It arises from the lower and medial impression on the upper part of the tuberosity of the ischium, by a tendon common to it and the long head of the biceps femoris; it also arises from an aponeurosis which connects the adjacent surfaces of the two muscles to the extent of about 7.5 cm. from their origin. The muscle is fusiform and ends a little below the middle of the thigh in a long round tendon which lies along the medial side of the popliteal fossa; it then curves around the medial condyle of the tibia and passes over the medial collateral ligament of the knee-joint, from which it is separated by a bursa, and is inserted into the upper part of the medial surface of the body of the tibia, nearly as far forward as its anterior crest.
