ABSTRACT

Background Outcomes of reverse shoulder arthroplasty (RSA) in patients with prior rotator cuff repair (RCR) remain inconsistent. The purpose of this study, therefore, was to systematically review the current outcomes literature on RSA in patients with prior RCR and to compare the results with controls without prior RCR. Methods A systematic review of the literature was performed, and outcome studies reporting on functional and clinical outcomes were included. Results A total of 11 studies encompassing 2879 shoulders were included. Improvements in postoperative patient-reported outcomes (PROs) from the baseline were higher in controls including the American Shoulder and Elbow Surgeons score (47.0 vs 39.5), Simple Shoulder Test (6.0 vs 4.9), Constant score (32.6 vs 26.4), and Visual Analog Scale for pain (−5.6 vs −4.9). Improvement in range of motion was greater in the control group, including external rotation (17° vs 11°), anterior elevation (56° vs 43°), and abduction (52° vs 43°). The overall complication rate (8% vs 5%) and revision rate (3% vs 1%) were higher in the RCR group. Discussion Differences in postoperative PROs and improvement from the baseline demonstrate a trend toward lower outcomes in patients with prior RCR but may be below the minimal clinically import difference. Level of evidence IV; systematic review
