INTRODUCTION Pigmented Villonodular Synovitis (PVNS) of knee joint is a rare disorder of Synovium. Hip and knee joint are commonly affected joints. The knee PVNS presents as a localized or diffuse form. Diagnosis if often delayed and permanent joint damage occurs with advanced disease. Ultrasound examination shows fluid collection and synovial hypertrophy. Magnetic resonance imaging helps in cl...

Pigmented Villonodular Synovitis (PVNS) is a relatively rare, benign proliferation lesion of the synovium of large joints. The etiology is varied and unclear. We had report a 79-year-old woman had PVNS after 14 years right hip arthroplasty with metal prosthesis. Here we report another 4 patients had PVNS after arthroplasty. The second one had PVNS in the 2(th) year after hip arthroplasty with b...

PURPOSE To review clinical characteristics of pigmented villonodular synovitis (PVNS) in China. METHODS Electronic medical records (EMR) of four Chinese institutes were queried for patients with histologically proven PVNS between January 2005 and February 2014. Their data were collected including gender, age at diagnosis, clinical presentation, affected site, symptom duration, comorbidities, ...

Pigmented villonodular synovitis (PVNS) is an uncommon proliferative disorder of the synovium, with an annual incidence of 1.8 per million. PVNS may have no symptoms, or may present as pain, stiffness, or swelling in a joint, with locking and instability. The proliferation of synovial villi and fibrous nodules characteristic of PVNS may occasionally form a palpable intra-articular mass. Resecti...

OBJECTIVE This retrospective observational study aims to explore the treatment procedure and outcomes of arthroscopically assisted radiotherapy for diffuse pigmented villonodular synovitis (PVNS) of the knee joint. METHODS From September 2006 to August 2011, 28 diffuse PVNS patients were diagnosed and treated under arthroscopy. Twenty six underwent post-operative radiotherapy. All patients we...

Extraarticular pigmented villonodular synovitis (PVNS) is very rare in the distal forearm. There has only been one previous case report of this disease in the extensor tendons of a child. We report a case of PVNS of the distal forearm that presented as two nodules over the radial aspect and a separate nodule on the ulnar aspect beneath the flexor carpi ulnaris tendon. Surgical exploration revea...

Sonography was successfully used to diagnose an effusion in the hips of three adults with septic arthritis and four with aseptic synovitis. The effusions were confirmed by aspiration. All the patients had markedly increased intracapsular pressure which, in the extended position, exceeded the systolic blood pressure and could well compromise the blood supply to the head of femur. Aspiration redu...
