Rotary mechanics after pes anserinus transplant

Since the medial hamstring muscles are primarily responsible for flexion and inward rotation of the tibia, various surgical techniques have been designed to alter functions of these muscles and to control anteromedial rotary instability resulting from ligamentous trauma. One such technique, the &dquo;pes anserinus transplant,&dquo; as developed by Slocum and Larson,’ was devised to control rotary mstability through changing the insertion of the common tendon of the gracilis and semitendinosus
