Our experience of five children with chronic thorn synovitis indicates that removal of free thorn fragments and all the macroscopically abnormal synovium is required in order to achieve a complete cure. Four children required total synovectomy for diffuse proliferative synovitis and one needed partial synovectomy of the area immediately around the embedded thorn. Joint washouts and partial syno...

Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative neoplastic condition affecting synovial-lined anatomic spaces. PVNS is characterized by hypertrophy of a synovial membrane by villous, nodular, and villonodular proliferation, with pigmentation secondary to hemosiderin deposition. The two forms of PVNS that have been described are diffuse (DPVNS) and localized (LPVNS). The...

Pigmented villonodular synovitis (PVNS) is benign proliferative disorder of the synovium of unknown origin. PVNS is divided into intra-articular and extra-articular form which may present as i) diffuse or ii) localised/nodular form. It is commonly seen in knee joint but hip, ankle, shoulder, wrist & other joints can be involved. It is usually seen in young adults from 20-50 years of age. It is ...

Two elite female athletes presented with anterior knee pain with range of motion and reproducible tenderness to palpation. Diagnostic arthroscopy was performed in both cases resulting in excision of a nodular pigmented villonodular synovitis (PVNS) in the first patient and scar tissue in the second patient. Correct diagnosis of anterior knee pain in the elite female athlete can present a challe...

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...

Pigmented villonodular synovitis (PVNS) is an uncommon benign proliferative disorder of synovium that may involve joints, tendon sheaths, and bursae. It most often affects the knees, and less frequently involves other joints. It presents in the temporomandibular joints (TMJs) extremely rarely. The authors report an elderly female patient with PVNS of the TMJ with skull base extension, who had t...
