Summary

Arthroscopic excision combined with external beam radiotherapy resulted in good clinical outcomes in the treatment of diffuse PVNS of the ankle.

Abstract

The current study presents the first case series of arthroscopic excision combined with external beam radiotherapy in the treatment of diffuse pigmented villonodular synovitis (PVNS) of the ankle. This study included six patients with diffuse PVNS of the ankle. Combined anterior and posterior approach of the ankle were used to perform the arthroscopic excision. Also, the concomitant chondral injury and bony impingement were resolved simultaneously. The external beam radiotherapy was undergone after the diagnosis of PVNS was confirmed by pathological examination. The patients were followed up for a mean of 49 months. There were no complications associated with the procedures. The mean AOFAS score improved from 59 points preoperatively to 86 points at the final follow-up (p = 0.001). All the patients had good or excellent results and no recurrence could be found. Arthroscopic anterior and posterior approach excision combined with external beam radiotherapy resulted in good clinical outcomes in the treatment of diffuse PVNS of the ankle, with lower recurrence rate, and without significant complications
