Arthroscopically-assisted mini open partial synovectomy for the treatment of localized pigmented villonodular synovitis of the knee. A retrospective comparative study with long-term follow up

摘要

Purpose The purpose of this study was to present the long-term results of treatment of localized pigmented villonodular synovitis (LPVNS) comparing two operative procedures of excision of the lesion-the arthroscopic and the arthroscopically assisted mini-open. We hypothesized that the latter approach allowed for treatment of LPVNS with acceptable recurrence rates, complication rates and functional outcomes.
