title: Localized pigmented villonodular synovitis: a rare cause of locking of the knee.
abstract: A 34-year-old woman presented with a history of recurrent episodes of knee locking and swelling. Arthroscopy revealed characteristic brown colored pedunculated lesions in the intercondylar notch region. These were clearly causing interference to joint motion. The lesions were resected arthroscopically with prompt resolution in symptoms. Histological examination confirmed pigmented villonodular synovitis.
