Pes anserinus (leg)
||It has been suggested that Guy ropes be merged into this article. (Discuss) Proposed since January 2016.|
Pes anserinus ("goose foot") refers to the conjoined tendons of three muscles that insert onto the anteromedial (front and inside) surface of the proximal extremity of the tibia. The muscles are the sartorius, gracilis and semitendinosus sometimes referred to as the guy ropes. The name, "goose foot", arises from the three pronged manner in which the conjoined tendon inserts onto the tibia.
The pes anserinus lies superficial to the tibial insertion of the medial collateral ligament of the knee.
It is a cause of chronic knee pain and weakness ("pes anserine bursitis"). Pes bursitis is a condition in which the medial portion of the knee is inflamed. If the bursa underlying the tendons of the sartorius, gracilis, and semitendinosus gets irritated from overuse or injury a person can develop this ailment. This condition usually occurs in athletes from overuse. This pathology is characterized by pain, swelling, and tenderness.
