What is goose foot tendonitis?

The goose foot, also called Pes anserinus, is an anatomical structure that is located on the medial aspect of the knee and is formed by the confluence of the tendons of three muscles:

• Sartorius: muscle originating in the iliac spine antero-superior on the anterior aspect of the pelvis and crosses the entire thigh diagonally. Their Actions they are flexion, abduction and external rotation of the hip and flexion and internal rotation of the knee.
• Graceful or internal rectum: muscle originating in the pubis and ischium (in the lower part of the pelvis) and runs down the thigh on its inner side. Its actions are adduction of the hip and flexion and internal rotation of the knee.
• Semitendinosus: muscle originating in the ischium and runs up the thigh along the back. Its actions are hip extension and knee flexion, as well as internal rotation of both joints.

In addition, covering the tendons is the Bursa anserina, which is a bag-like structure with serous fluid inside in order to soften the friction on these tendons.

Goose foot syndrome is inflammation of one or both of these structures.
