Abstract

The current treatment methods for diffuse intraarticular or extraarticular type pigmented villonodular synovitis (PVNS) include arthroscopic synovectomy or staged anterior and posterior open synovectomies. However, it is unclear whether simultaneous anterior and posterior synovectomies achieve local control and recovery of function. We therefore determined the recurrence rate and function in patients with diffuse PVNS treated with anterior and posterior synovectomies and adjuvant radiotherapy. We retrospectively reviewed all 19 patients with diffuse PVNS involving the knee treated with anterior and posterior synovectomies and adjuvant radiotherapy between January 2001 and November 2007. From the records, we determined local recurrence and Tegner-Lysholm scores. The minimum followup was 42 months (median, 98 months; range, 42-143 months). Postoperative MRI revealed residual tumor in five of the 19 patients, although three had no disease progression during followup and had knee scores of 86 to 90. Two patients had recurrences at 6 and 9 months with knee scores of 88 at 42 months and 90 at 68 months. The mean Tegner-Lysholm knee score improved from 59 to 93 points. Mean maximum extension and flexion angles improved from 11° to 2° ...Continue Reading
