Long-term pressure on the popliteal artery can cause the artery to narrow (stenosis), causing pain and cramping with just slight activity, such as walking. In severe cases or when undiagnosed, the nerves and muscles in the leg can become damaged. Blood clots may occur in the lower leg (deep vein thrombosis).
The knee joint blood supply is derived from a rich anastomosis of the five major constant arteries, namely, the superior medial and lateral, the middle (posterior), and the inferior medial and lateral genicular arteries.

Find the fleshy middle portion of the back middle of your knee. Doctors call this the “popliteal fossa.†Others call it the “kneepit†for short. Press with increasing pressure until you feel a pulsation in the back of the knee. The pulsation will feel like a heartbeat, usually steady and even in nature.
The posterior tibial artery passes posterior to the popliteus muscle and pierces the soleus muscle. The posterior tibial artery then descends between the tibialis posterior and flexor digitorum longus muscles. The posterior tibial artery supplies blood to the posterior crural compartment.
A popliteal aneurysm is a bulge in a blood vessel (artery) behind your knee. The bulge occurs in a weak spot in the artery. It may occur in one or both legs. Blood clots can form in this type of aneurysm and block blood flow in your leg.
The muscle and tendons near the knee are positioned so that they compress the popliteal artery – the main artery that runs through and behind the knee. Compression of the artery restricts blood flow to the lower leg and can damage the artery.
The Popliteal vein: It is superficial to the and travels with the Popliteal artery. The Tibia nerve and common Fibular nerve: These are the two major branches of the Sciatic nerve. They are the most superficial of the neurovascular structures in the Popliteal fossa.
The dorsalis pedis artery (dorsal artery of foot), is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery.The dorsalis pedis artery (dorsal artery of foot), is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. A continuation of the femoral artery in the inner thigh, the popliteal artery travels across the popliteal fossa — the pit behind the knee joint — before terminating into two branches: the anterior and posterior tibial arteries.
Popliteal fossa pain is developed by a wide variety of causes. The most common causes are Baker's cyst, soft tissue or bone tumor and injury to the meniscus, hamstring, popliteal tendon or ligament.
The popliteal pulse is named after your popliteal artery. This is an important blood vessel that carries blood down through your leg to your feet. So the location of your popliteal pulse is behind your knee. This keeps the artery out of the way of the bones and tendons in the soft tissue.
Plantar arteries: The plantar arteries—lateral, medial, and deep—form a looping web of arteries across the foot and down through each toe. They eventually unite with the dorsalis pedis artery. Dorsalis pedis: This artery supplies blood to the surface of the foot as a continuation of the anterior tibial artery.
The superficial system is visible on the surface of our skin, if a tourniquet is applied. These veins are commonly used to sample blood for blood tests. The superficial veins drain into deep veins (which share the same names as the arteries they run along).
Great saphenous vein.

It usually lies between the sartorius and the garcilis muscles and supplies their distal ends. The artery accompanies the saphenous nerve. It usually supplies the skin on the medial and proximal part of the leg.
Saphenous ArteryA branch of the descending genicular artery, the last branch (most distal) of the femoral, the saphenous is also variable. It usually lies between the sartorius and the garcilis muscles and supplies their distal ends. The artery accompanies the saphenous nerve.
In anatomy, the saphenous opening (saphenous hiatus, also fossa ovalis) is an oval opening in the upper mid part of the fascia lata of the thigh. It lies 3–4 cm below and lateral to the pubic tubercle and is about 3 cm long and 1.5 cm wide.
The great saphenous vein (GSV, alternately "long saphenous vein"; /səˈfiËnÉ™s/) is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle.

Saphenous neuritis is a painful condition caused by either irritation or compression at the adductor canal or elsewhere along the course of the saphenous nerve. The condition also may be associated with surgical or nonsurgical trauma to the nerve, especially at the medial or anterior aspect of the knee.
The Small Saphenous Vein (SSV) is a superficial vein of the posterior leg. It drains the leg's lateral surface and runs up the leg's posterior surface to drain into the popliteal vein.
The main tributaries of the great saphenous vein in the thigh region are: the superficial epigastric vein, the superficial iliac circumflex vein, the external pudendal veins and the accessory saphenous vein.
A popliteal aneurysm is
bulging and weakness in the wall of the popliteal artery, which supplies blood to the knee joint, thigh and calf.
Common symptoms include:
- Pain behind the knee.
- An edema (collection of watery fluid) in the lower leg.
- Foot pain.
- Ulcers on the skin of the feet that don't heal.
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg.

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.).
Despite its small size, the popliteus is a major stabilizer of the knee. The popliteus is involved in both the closed chain phase and open chain phase of the gait cycle. During the closed chain phase, which is when the foot is in contact with the ground, the muscle externally rotates the femur on the tibia.
Primarily, the anterior tibial artery serves to deliver oxygenated blood to the front portion of the lower leg, which is called the “anterior crural compartment.” As such, and via its branches, it supplies nerve, muscular, and other tissues of the front of the lower-leg, as well as the skin.
The patella is a small bone located in front of the knee joint — where the thighbone (femur) and shinbone (tibia) meet. It protects the knee and connects the muscles in the front of the thigh to the tibia.
The popliteal artery is the direct continuation of the superficial femoral artery, at the point where it exits the adductor canal at the adductor hiatus, and passes into the popliteal fossa as the vessel courses posteriorly behind the knee.
