The sartorius muscle can move the hip joint and the knee joint, but all of its actions are weak, making it a synergist muscle. [4] At the hip, it can flex, weakly abduct, and laterally rotate the femur. [4] At the knee, it can flex the leg; when the knee is flexed, sartorius medially rotates the leg.

Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...

The tendons at the ends of the rotator cuff muscles can become torn, leading to pain and restricted movement of the arm. A torn rotator cuff can occur following trauma to the shoulder or it can occur through the "wear and tear" on tendons, most commonly the supraspinatus tendon found under the acromion.
The pes anserinus is where the tendons of the sartorius, gracilis, and semitendinosus join at the medial knee, [1] into the anteromedial proximal tibia. Pes anserine bursitis may result from stress, overuse, obesity and trauma to this area. An occurrence of pes anserine bursitis commonly is characterized by pain at the medial knee and upper ...
The shoulder joint is muscle-dependent, as it lacks strong ligaments. The primary stabilizers of the shoulder include the biceps brachii on the anterior side of the arm and tendons of the rotator cuff, which are fused to all sides of the capsule except the inferior margin. [5]
An incision is made over the medial knee 4 cm medial to the patella, and extended distally 7 to 8 cm past the joint line, directly over the pes anserinus tendons. [27] Within the distal borders of the incision, the semitendinosus and gracilis tendons are found beneath the sartorius muscle fascia.
