Background: Severe shoulder instability after initial dislocation may occur with disruption of the soft tissue and osseous restraints. Methods: Four elderly female patients, who had a large deficit of the anteroinferior aspect of the glenoid with subluxation of the humeral head through a rent in the anterior capsulolabral complex, sustained an acute recurrence of instability. Arthroscopic capusulolabral and rotator cuff repair was performed using suture anchors. Results: In all patients, stability was not restored following anchor fixation. Of the four patients, three had anteroinferior subluxation of the humeral head postoperatively. All of three patients had developed glenohumeral arthrosis and unsatisfactory functional scores at 1-year follow up. Conclusion: Age at the time of initial dislocation, residual joint instability, and the intra-articular operative procedure to stabilize the glenohumeral joint potentially influenced the development of postoperative arthrosis.
