A 40-year-old woman with recurrent pigmented villonodular synovitis of the knee was treated with /sup 90/Y radiocolloid. The advantages of /sup 90/Y include effectiveness, low cost, simplicity, and low morbidity. The radiophysical properties of /sup 90/Y that make it a useful therapeutic agent are short half-life, pure beta emission and good penetration of the soft tissues. Side effects are few, predictable, and for the most part, avoidable. Radionecrosis of soft tissue, needle tract pigmentation, injection site tenderness, pyrexia, and lymphocyte chromosomal abnormalities have been reported. The indications for intra-articular radiocolloid therapy are the same as for surgical synovectomy, except that it is reserved for patients older than 35 years of age. The pathologic events following /sup 90/Y therapy in experimental animals show coagulation necrosis of the synovium, followed by an intense inflammatory reaction, leading ultimately to fibrosis. /sup 90/Y is a useful adjuvant in the treatment of recurrent pigmented villonodular synovitis.
