the fibular bursa between the lateral (fibular) collateral ligament and the tendon of the biceps femoris; the fibulopopliteal bursa between the fibular collateral ligament and the tendon of the popliteus; and the subpopliteal recess (or bursa) between the tendon of the popliteus and the lateral condyle of the femur
It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries. The deepest (most anterior) structure in the fossa, the popliteal artery runs close to the joint capsule of the knee as it spans the intercondylar fossa. Five genicular branches of the ...
The suprapatellar bursa, the largest bursa, extends the joint space anteriorly and proximally. The subpopliteal recess and semimembranosus bursa are located posteriorly and are much smaller; The lateral and medial subtendinous bursae of gastrocnemius are located at the origin of the two heads of the gastrocnemius muscle. Non-communicating bursae:

The popliteal fossa (also referred to as hough or kneepit in analogy to the cubital fossa) is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia.
Posteriorly below the knee joint, the popliteus stretches obliquely from the lateral femoral epicondyle down to the posterior surface of the tibia. The subpopliteal bursa is located deep to the muscle. Popliteus flexes the knee joint and medially rotates the leg. [25]
The popliteus muscle in the leg is used for unlocking the knees when walking, by laterally rotating the femur on the tibia during the closed chain portion of the gait cycle (one with the foot in contact with the ground). In open chain movements (when the involved limb is not in contact with the ground), the popliteus muscle medially rotates the ...
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...
