Pes anserinus is a Latin term that refers to the goosefoot-shaped tendons located on the lower part of the inner knee. The pes anserinus tendons are responsible for stabilizing the knee joint and enabling smooth movement. While there are no direct synonyms for this term, it is sometimes described as the pes anserine bundle or the goosefoot tendons. Additionally, the individual tendons within the pes anserinus group have their own names: the sartorius tendon, the gracilis tendon, and the semitendinosus tendon. Understanding the anatomical terms related to the knee joint is essential for proper diagnosis and treatment of knee injuries.
