Description[edit | edit source]
The Popliteal Fossa is a diamond- shaped space behind the knee joint .[1] It is formed between the muscles in the posterior compartments of the thigh and leg.This anatomical landmark is the major route by which structures pass between the thigh and leg.[2]
Margins[edit | edit source]
The Popliteal Fossa has 2 upper margins and 2 lower margins[2]
- The margins of the upper part are formed by the Semimembranosus and Semitendinosus muscles on the medial side and the Biceps Femoris on the lateral side.
- The margins of the lower parts are formed by the medial head of the Gastrocnemius muscle and the laterally by the Plantaris muscle and the lateral head of the Gastrocnemius muscle.
Floor[edit | edit source]
The floor of the fossa is formed by the Popliteal surface of the Femur, Capsule of the Knee reinforced by the oblique Popliteal ligament and the Popliteus muscle covered by its Fascia[1].
Roof[edit | edit source]
The roof of the Popliteal fossa is covered by the Fascia Lata which is strongly reinforced by tranverse fibers. The roof is pierced by the small Saphenous vein and the posterior Femoral cutaneous nerve[1].
Content[edit | edit source]
The major content of the Popliteal fossa are the Popliteal artery,the Popliteal vein, the Tibia nerve and Common Fibular nerve.Clinical Significance[edit | edit source]
- Baker's cyst
- Popliteal Pulse
- Popliteal Aneurysm
