Glenohumeral Arthrosis in Anterior Instability before and after Surgical Treatment

Abstract

Similar factors contribute to preoperative and postoperative arthritis in patients with anterior glenohumeral instability, suggesting that surgery does not influence the risk factors of arthritis. Although decreased external rotation with the arm at side statistically correlated with arthritis in this study, the authors were unable to establish this as an effectual relationship because nearly all patients with glenohumeral osteoarthritis, whether instability related or not, have decreased external rotation.
