Endoscopic Resection of the Lateral Ankle Bursa With Synovial Chondromatosis

Abstract

Bursal chondromatosis is synovial chondromatosis of the bursae. It is a rare disease entity that can involve the adventitial bursa of the lateral ankle. Complete synovectomy, removal of loose bodies, and bursectomy comprise the treatment of choice. Detailed preoperative radiologic assessment and surgical planning are the keys to success. Any accompanying synovial chondromatosis of the ankle or subtalar joint or tenosynovial chondromatosis of the peroneal tendon sheath should be treated together with the bursectomy. Endoscopic bursectomy can be performed through the bursal portal. The proximal and distal peroneal tendoscopy portals serve as viewing portals. The resection of the diseased tissues should be performed in a step-by-step zonal manner. Complete synovectomy and removal of loose bodies should be performed before bursectomy. Internal drainage of the bursal sac into the peroneal tendon sheath may be indicated if the sac is adherent to the skin. It should only be performed after complete synovectomy and removal of loose bodies.

Arthroscopic Management of Anterior Ankle Synovial Osteochondromatosis

“…It is also important to detect any disease involvement of adjacent structures. [10][11][12] The locations of loose bodies and inflamed synovitis and the presence of concomitant pathologies are important information for surgical planning.…”
