PURPOSE: Pigmented villonodular synovitis (PVNS) is a rare soft tissue tumor, which usually arises in larger joints, such as the knee. It has a high recurrence rate after surgical treatment. The purpose of this study is to evaluate and analyze the clinical results of diffuse-type pigmented villonodular synovitis cases that were treated with open total synovectomy. 0aMATERIALS AND METHODS: Between 1994 and 2006, 21 patients who had diffuse-type pigmented villonodular synovitis were selectively reviewed. Among the 21 cases studied, 14 patients presented at the knee, 5 at the ankle, and 2 at the shoulder and elbow. The mean follow up period was 5.5 years (range, 36-157 months). The average age of the patients was 34 years consist of 7 men and 14 women. Clinical outcomes were analyzed retrospectively, including range of motion and complications. 0aRESULTS: Open total synovectomy and adjuvant electrocautrization were done in all cases except one. During the regular follow-up period after the surgery, two patients showed symptoms of recurrence. After re-operation, only one case was pathologically confirmed as a recurrence. The patient who had partial synovectomy and the other patient who had second operation due to recur rence received additional radiation therapy. Clinical outcome scores were improved in every aspect (p<0.0001). 2 out of 14 Patients who had pigmented villonodular synovitis at the knee developed stiff knee after the surgery. 0aCONCLUSION: After the open total synovectomy with electrocautrization, a low recurrence rate and satisfactory clinical outcome was achieved, observed in a minimum of 3 years of follow-up
