Pigmented villonodular synovitis. A follow-up study.
Pigmented villonodular synovitis (PVS) was diagnosed in 25 patients during the period 1950--76. Twenty-two of the patients were re-examined 2--28 years later. Three patients with local affection of tendon sheaths, treated by excision, were all free of symptoms at follow-up. Nineteen patients all with unilateral knee joint affection were divided into two groups according to peroperative findings, 6 localized PVS and 13 diffuse PVS. The 6 patients with localized PVS all had normal knee movement at follow-up, whereas the 13 with diffuse involvement had varying impaired knee mobility.
