Published results showed arthroscopic synovectomy may be safe, with good clinical outcomes and no clinical recurrences for treatment of diffuse pigmented villonodular synovitis.

Between 2009 and 2012, researchers performed complete synovectomy in 21patients with diffuse pigmented villonodular synovitis through posteromedial, posterolateral, anteromedial and anterolateral portals. Researchers used Lysholm and IKDC scores to evaluate patients before treatment and at a minimum 5-year follow-up.

Results showed no complications during or after the arthroscopic procedure. Researchers found evidence of local recurrence without clinical signs among two patients during the follow-up period. Researchers also noted significant improvements in the limitation of joint motion, Lysholm knee joint function score and IKDC score postoperatively, as well as no evidence of swelling, infection, joint stiffness and neurovascular lesions.

“Arthroscopic treatment of [diffuse pigmented villonodular synovitis] DPVNS through the four arthroscopic portals (anterior and posterior) has fewer complications and relatively shorter postoperative recovery time,” the authors wrote. “It could be used, safely and easily, while ensuring satisfactory control of diffuse PVNS with low recurrence rates. Intra-articular DPVNS of the knee could be treated with attentive arthroscopic synovectomy without requiring for postoperative chemoradiotherapy.” – by Casey Tingle
