Diagnosis and treatment of postarthroscopic synovial knee fistulae: a report of four cases and review of the literature.

Abstract

Development of synovial knee fistulae following arthroscopic knee surgery is a rare but under-reported complication. The diagnosis and treatment of this complication is described in a series of four patients. Synovial knee fistula formation is a benign complication and in the majority of patients it can be treated conservatively with immobilization until healing occurs. The presence of infection should always be excluded.
