Abstract: 【Abstract】〓Objective〓To investigate the method and the clinical effect of arthroscopic therapy on localized pigmented villondular synovitis of knee. Methods〓The clinical material and therapy were reviewed retrospectively in 10 cases with localized pigmented villondular synovitis of knee confirmed by the MRI images, biopsy, surgery and pathology from September 2008 to May 2014. Follow-up of 9 months to 68 months, the functional recovery such as the postoperative knee pain, swelling and range of motion were evaluated according to the Lysholm knee functional score. Results〓All of 10 patients have no complications occurred in the postoperative follow-up period, and 2 patients relapse. The Lysholm knee functional score was 91.80±5.28 points, and obviously higher than which before surgery(47.50±16.28, P<0.01). Conclusion〓Arthroscopic therapy is an effective treatment with less invasion, fast recovery, and better function on localized pigmented villondular synovitis.
