A Novel Technique of Resecting Localized Pigmented Villonodular Synovitis of the Knee Joint

Pigmented villonodular synovitis is an uncommon benign proliferation of the synovium. In the knee joint, it can present as a localized or a diffuse form and can mimic numerous conditions.

We present a case report of a 54-year-old male with localized form of this condition. The diagnosis is not often made clinically but usually made with the help of magnetic resonance imaging and histopathology. We used a novel technique for resecting the tumor by arthroscopy.

A high index of suspicion is required for the diagnosis of the condition and arthroscopic excision results in lower morbidity and lesser recurrence rates.
