Pes anserinus

Pes anserinus (literally "goose's foot") is the anatomic name given to the conjoined tendons at the medial aspect of the knee which insert onto the anteromedial aspect of the tibia. Its name comes from the webbed-foot appearance of the tendons insertion onto the tibia.

The three tendons that form the pes anseriunus (from anterior to posterior) are:

Mnemonics for remembering the three conjoined tendons that make up pes anserinus include :


A bursa (known as the pes anserinus bursa) lies between the pes anserinus tendons and the more deeply located semimembranosus tendon at the level of the knee joint. This bursa can become inflamed and be symptomatic: pes anserinus bursitis.  


The term "pes anserinus" may also be used to describe the branching point of the facial nerve (CNVII) within the parotid gland.
