Abstract

|
Purpose: To purpose of this study was to review the long-term follow up results of surgical treatment of the localized pigmented villonodular synovitis in the knee.
Material and Methods : We evaluated and analyzed 6 patients (6 cases) who underwent arthroscopy and excisional biopsy as pigmented villonodular synovitis from March 1988 to June 2002. The clinical diagnosis was confirmed by pathologic findings. All patients had been managed with arthroscopic excision, but two patients underwent mini-open excision. The recurrence was evaluated by the loss of preoperative symptom and physical examination for range of motion, pain and finding of swelling.
Results: According to the arthroscopic findings, all patients had localized form of pigmented villonodular synovitis. Three patients had pedunculated type (one of them had torsion) and the two patients had nodular type and one patient had mixed type. All patients had improvement in pain, swelling and range of motion and there was no evidence of recurrence.
Conclusion: In terms of long term follow up results, precise preoperative diagnosis and the adequate surgical treatment, especially arthroscopic excision for the localized pigmented villonodular synovitis, would be considered one of the fundamental modality to expect the good results.
