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

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 approac...

Description
Summary: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. Methods Between 1990 and 2006, 21 patients with LPVNS were treated with partial synovectomy through an arthroscopically-assisted mini open technique (group A), and 23 patients were treated with an arthroscopic excision of the lesion (group B). All patients were clinically examined at one, three, and 12 months post-operatively and graded by the Lysholm knee score and the Ogilvie-Harris score. Results The mean Lysholm score was improved from 58.7 ± 9 to 94.2 ± 7 for group A (p
