Abstract

A suprapatellar plica is a persistent remnant of the embryologic synovial membrane between the suprapatellar pouch and the knee joint. Pathologic synovial plica is not a common entity, however, when present, it can mimic a variety of clinical situations. We describe here a case of pathologic suprapatellar plica that has a check-valve mechanism, which results in a clinical presentation as knee joint swelling.
