The popliteal fossa (sometimes referred to as the kneepit) is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia.

Boundaries

The boundaries of the fossa are:[1]

  Medial Lateral
Superior superior and medial:
the semimembranosus muscle
superior and lateral:
the biceps femoris muscle
Inferior inferior and medial:
the medial head of the gastrocnemius muscle
inferior and lateral:
the lateral head of the gastrocnemius muscle and plantaris muscle

Roof

The roof is formed by (from superficial to deep):[1]

  1. skin
  2. superficial fascia, which contains the small saphenous vein, the terminal branch of the posterior cutaneous nerve of the thigh, posterior division of the medial cutaneous nerve, lateral sural cutaneous nerve, and medial sural cutaneous nerve
  3. deep fascia or popliteal fascia

Floor

The floor is formed by:[1]

  1. the popliteal surface of the femur
  2. the capsule of the knee joint and the oblique popliteal ligament
  3. strong fascia covering the popliteus muscle

Contents

Structures within the popliteal fossa include, (from superficial to deep):[1]

It is of note that the common fibular nerve also begins at the superior angle of the popliteal fossa.[5]
