The current treatment of choice for diffuse-type pigmented villonodular synovitis (PVNS) is surgical excision. Complete synovectomy is necessary because of the local aggressiveness of the disease, with a significant recurrence rate and a minor chance of malignant transformation. The recurrence rate is even greater in those cases with extra-articular extension. Arthroscopic and endoscopic synovectomy have the advantage of avoidance of extensive soft-tissue dissection, which is associated with open synovectomy. The purpose of this Technical Note is to describe the details of combined arthroscopic and endoscopic synovectomy as treatment for diffuse PVNS of the ankle. By a combination of different arthroscopic and endoscopic approaches of the ankle region, a complete synovectomy of both intra-articular and extra-articular components of diffuse-type PVNS is feasible.
