  • The poplitealfossa
    The distal continuation of the adductor canal
  • The poplitealfossa. (a) Superficial dissection. (b) Deep dissection.
  • Boundaries
    superolaterally—biceps tendon;
    superomedially—semimembranosusreinforced by semitendinosus;
    inferomediallyand inferolaterally — the medial and lateral heads of gastrocnemius.
    Roof : fascia latawhich is pierced by the small saphenous veinas this enters the poplitealvein & posterior femoral cutaneous nerve.
  • Floor
    from above down, is formed by:
    Popliteal surface of the femur;
    Capsule of the knee joint;
    Oblique popliteal ligament;
    Popliteusmuscle covering the upper posterior surface of the tibia.
  • Contents
    The common peroneal nerve passes out of the fossa along the medial borderof the biceps tendon;
    The tibial nerve is first lateral to the popliteal vessels and then crosses superficially to these vessels to lie on their medial side.
    The popliteal vein lies immediately superficial to the artery;
    The popliteal artery itself lies deepest of all in the fossa.
