Torsion and subsequent ischaemia is a well-recognised cause of symptoms and morbidity in general surgery. We present three cases of solitary pigmented villonodular tumours of the knee which were found to have undergone torsion. We believe these to be the first intra-articular tumours in which torsion has been reported.

UNLABELLED Radisosynovectomy (RS) is a local form of radionuclide therapy used in various forms of arthritis characterized by synovitis. In hemophilic arthropathy, RS provides removal of inflamed synovium and prevents further joint damage. This review focuses on the practical aspects of radionuclide synovectomy in hemophilic patients and describes the issues both related to the methodology and ...

The phenomenon of increased spontaneous incorporation of 3H-thymidine (3H-TdR) into peripheral blood mononuclear cells in rheumatoid arthritis (RA) has been investigated. The activity was found to be short lived and affected less than 1% of cells. Using a Percoll density gradient we identified two populations of active cells. RA patients with active synovitis and increased 3H-TdR incorporation ...

We present the diagnosis of bilateral granulomatous inflammation of the hip joints associated with Hylan G-F 20 viscosupplementation injections. Clinicians recommending therapeutic Hylan injections for the management of hip arthritis should maintain clinical awareness regarding this potential complication.

REASONS FOR PERFORMING STUDY The influence of synovial fluid culture on short- and long-term prognosis of cases with septic synovitis requires study. HYPOTHESES Horses with a positive bacterial culture from septic synovial fluid are less likely to survive or return to successful athletic function than those with a negative bacterial culture from septic synovial fluid. METHODS Records of mat...
