Pes Anserine Bursitis

• Inflammation of the bursa (fluid vesicle) that is joined together with the pes anserine tendons that consist of: 

• Semitendinosus, gracilis, and sartorius 

• Located along the medial (inside) knee (two inches below knee joint line) 

• A bursa is a fluid filled vesicle that secretes synovial fluid to reduce friction between tissues and works as a cushion for bones, tendons and muscles

• Inflammation of a bursa is not usually a sudden onset, it progresses over time and can occur in the shoulder, knee, hip, elbow and big toe.
