The effect of glenoid bone loss and rotator cuff status in failed anatomic shoulder arthroplasty after revision to reverse shoulder arthroplasty.

Hypothesis: We evaluated outcomes and the risk of re-revision in patients with a failed anatomic total shoulder arthroplasty (TSA) revised to a reverse shoulder arthroplasty (RSA) based on rotator cuff deficiency and glenoid bone loss.

Methods: From 2004 to 2017, 123 patients with failed TSAs underwent revision to RSAs with minimum 2-year follow-up. Preoperative radiographs were evaluated to determine whether the glenoid component was fixed or loose.

Does the etiology of a failed hemiarthroplasty affect outcomes when revised to a reverse shoulder arthroplasty?

Background: The purposes of this study were to evaluate patient outcomes after revision of hemiarthroplasty to reverse shoulder arthroplasty (RSA) based on initial pathology, to determine the re-revision rate, and to identify characteristics that may predict subsequent re-revision.

Methods: A total of 207 shoulder hemiarthroplasty, bipolar prosthesis, and humeral resurfacing cases revised to RSA between January 2004 and January 2017 were reviewed. Outcome measures included shoulder motion and American Shoulder and Elbow Surgeons and Simple Shoulder Test (SST) scores.
