[Severe cartilage loss caused by metallic anchors in surgical treatment of a Bankart lesion: report of three cases].

Currently, arthroscopic modalities in the surgical treatment of shoulder instability using suture anchors are more popular than open surgery. However, there are some complications related to the metallic suture anchors used. One of the most common complications is cartilage loss due to shallow placement of the suture anchor. Herein, we report three cases with severe cartilage loss of the humeral head due to metallic proud anchors, including one of whom requiring total shoulder arthroplasty. In conclusion, it is essential to place the suture anchors in an appropriate position and deepness. In case of any doubt, they should be removed or in non-threaded anchors, they should be inserted fully inside the glenoid with an impactor and a hammer to avoid serious cartilage loss.
