Inflammation of the bursa 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.
Typically occurs with repetitive motions of knee flexion (bending) and hip adduction or direct trauma to the bursa
Can also be secondary to medial meniscus tear/fraying - check knee range of motion (knee should be able to bend to buttock)
