Pigmented Villonodular Synovitis:A Follow-up Study

Abstract

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.

Localized pigmented villonodular synovitis with hemorrhage arising from lateral meniscocapsular junction: A case report

“…[1] Pigmented villonodular synovitis is a part of a disease spectrum of giant cell tumor of the tendon sheath (GCTTS) and the intra-articular dominant form of GCTTS is referred to as PVNS. [8] The etiology of the disease is unknown; however, there are three theories: [9] neoplasia, a process associated with a disorder of the lipid metabolism, and chronic inflammation due to repeated trauma or hemorrhage. Pigmented villonodular synovitis is often localized in the knee and it is seen much less frequently in other joints.…”

Villonodular Synovitis of the Shoulder in the Elderly

“…V illonodular synovitis (VS) is a benign lesion characterized by the proliferation of the lining tissues of joints. The lesion varies in size and form, affecting mainly young adults with a peak incidence in the third and fourth decades 1,2 . The knee joint is the site most commonly affected by VS 3,4 .…”
