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 depression at the back of the knee, or kneepit is the popliteal fossa, colloquially called the ham. The tendons of the above muscles can be felt as prominent cords on both sides of the fossa—the biceps femoris tendon on the lateral side and the semimembranosus and semitendinosus tendons on the medial side.
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.
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. [50] The pudendal (S2-S4) and coccygeal nerves (S5-Co2 [check spelling]) supply the muscles of the pelvic floor and the surrounding ...

The popliteal artery entrapment syndrome (PAES) is an uncommon pathology that occurs when the popliteal artery is compressed by the surrounding popliteal fossa myofascial structures. [1] This results in claudication and chronic leg ischemia. This condition mainly occurs more in young athletes than in the elderlies. [2]
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 popliteal fossa is to be examined bilaterally (on both sides) 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 angiography and MR angiography may also be employed. [2]
