Injury to the common peroneal nerve is seen with posterolateral knee injury. Examples of passive stabilizers include the medial collateral ligament (MCL), lateral collateral ligament (LCL), anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL), while examples of active stabilizers consist of the hamstrings, extensor mechanisms, and the popliteus muscle. SMT may benefit from proper shoe fit to prevent overpronation or a medial heel lift in patients with genu valgum. Proper shoe fits are stable running shoes and shoes with motion control technology, they provide extra support preventing your ankle from rolling inwards extremely. Wearing these shoes is even more important when you are overweight.

End range lengthening should be avoided if painful in this stage. Pain and swelling of the bursa are caused by inflammation, external pressure, or overuse. The patellofemoral joint and lumbar spine may both refer pain to the posterior knee. The popliteal fossa is also composed of nerves (posterior femoral cutaneous, common peroneal and tibial), vascular structures (small saphenous vein, popliteal artery and popliteal vein), bursae, lymph nodes, and fat.

A Bakerâs cyst is caused either by a herniation of the synovial membrane through the posterior capsule or by an escape of fluid through an anatomic bursa next to semimembranosus or gastrocnemius.
