Successful use of bioabsorbable anchors for capsulolabral and rotator cuff repair is well documented. The bioknotless anchor (DePuy mitek) has demonstrated reliable fixation of these pathologies. However, this poly (L-lactide) polymer has recently demonstrated some similar complications to those documented for the earlier polyglycolic acid implants; namely synovitis and chondral damage with osteolysis. We report three cases with osteolysis and chondral damage associated with bioknotless anchors. A prospective record of shoulder arthroscopy is maintained by the senior author. From this, three patients with post-operative complications of arthropathy and osteolysis, following bioabsorbable anchor repair of capsulolabral lesions were identified. A retrospective review of case notes, radiographs, operative records and intraoperative video and photographic material was undertaken.Background
