Anatomy: The semimembranosus muscle originates with a flat tendon from the superolateral part of the ischial tuberosity, the biceps femoris and semitendinosus muscles, travels deep to the semitendinosus muscle to divide into five components and insert at the tubercle of the medial tibial condyle, the medial margin of the tibia, the fascia over the popliteus muscle, and the lateral femoral condyle where it forms much of the oblique popliteal ligament. The muscle belly ends and the tendon begins just above the knee joint. semimembranosus, adductor magnus. The other two are the semimembranosus muscle and the biceps femoris.

These individual muscles—BF, SM, ST—serve different functions and exert a specific role and a specific contact times while walking, running, or turning, although their anatomy partially overlaps proximally (2). The hip, ankle, and foot morphology should be evaluated for biomechanical features that can predispose to semimembranosus tendon overuse. Risk is increased by activities that involve repetitive and/or strenuous use of the knee and hip (distance running, triathlon, race walking, weightlifting, or climbing , running down hills. The hamstrings are closely related to each other as they share a common origin point, and . sartorius, and semimembranosus muscles (30), and in calves. Injury Mechanism and Physical Examination.

Resisted flexion of the knee at 90° can make the semimembranosus tendon more prominent for easier palpation. The semitendinosus is located at the posterior and medial (inner) part of the thigh and the semimembranosus is the most medial of the hamstring muscles. According to the analyzed data, about 13% of the induced semimembranosus muscle displacement could be tracked in the collagenous tissue layer encapsulated in the subcutaneous fat. semimembranosus Protein nitration with aging in the rat semimembranosus and soleus muscles.

Snapping knee syndrome is caused by subluxation of the gastrocnemius and semimembranosus tendons and typically presents in avid athletes. Semimembranosus trigger point diagram, pain patterns and related medical symptoms. The semimembranosus and semitendinosus muscles are referred to as the medial hamstrings and participate in flexion and medial rotation of the knee joint (, 20). One might hypothesize that this is related to increased valgus stress and the Q angle present in women.
