The knee bursae are the fluid-filled sacs and synovial pockets that surround and sometimes communicate with the knee joint cavity. The bursae are thin-walled, and filled with synovial fluid. They represent the weak point of the joint, but also provide enlargements to the joint space.[1] They can be grouped into either communicating and non-communicating bursae or, after their location – frontal, lateral, or medial.
