Outcomes After Revision Arthroscopic Rotator Cuff Repair: A Systematic Review

Background: Arthroscopic rotator cuff repair (ARCR) is one of the most commonly performed orthopaedic procedures; however, it is unclear how to manage patients with symptomatic retears.Purpose: To perform a systematic review to evaluate the outcomes of revision ARCR in the literature.Study Design: Systematic review; Level of evidence, 4.Methods: A systematic literature search based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed utilizing the Embase, MEDLINE, and Cochrane Library databases. Eligible for inclusion were clinical studies reporting on revision rotator cuff repair. Clinical outcomes were recorded.Results: The 17 included studies were composed of 888 shoulders in 885 patients. The mean age of the 885 patients was 58.6 +/- 9.1 years, with a mean follow-up of 28.1 +/- 22.1 months. The mean visual analog scale score was 2.1 +/- 1.8, the mean American Shoulder and Elbow Surgeons score was 75.0 +/- 18.3, and the mean Constant score was 67.4 +/- 16.6. The overall rate of retears after revision was 25.3%, with an 8.0% reoperation rate including 2.7% undergoing reverse shoulder arthroplasty and 2.0% undergoing subsequent rotator cuff repair. Finally, the complication rate was 8.6%.Conclusion: Revision ARCR improved patient-reported outcomes, with 92% of patients free from reoperations at a mean follow-up of 2 years. Overall, 78.4% of patients were satisfied at final follow-up; however, the rate of retears was found to be higher than after primary ARCR.
