Reverse total shoulder arthroplasty (RTSA) is now performed at nearly the same rate as anatomic total shoulder arthroplasty in the United States. Repair of the subscapularis is of vital importance in total shoulder arthroplasty; however, its utilization in RTSA has recently been questioned.MethodsThis is a retrospective comparative study from prospectively collected data comparing the outcomes and complications after primary RTSA with or without subscapularis repair. The study includes 202 patients who underwent primary RTSA at a single institution by a single surgeon using the same implant between 2007 and 2012. Average clinical follow-up was greater than 3 years in both groups. Outcome scores, clinical range-of-motion and strength measurements, and complications including dislocations are reported.ResultsAt an average follow-up of greater than 3 years, there were no significant differences in clinical range of motion, strength, and rates of complications including dislocations. External rotation was 24° in the subscapularis repair group and 26° in the no-repair group. There were no differences in the American Shoulder and Elbow Surgeons shoulder score. Subjective measures included the Shoulder Pain and Disability Index; University of California, Los Angeles shoulder rating scale; Simple Shoulder Test; and normalized Constant outcome scores. There were 0 dislocations (0%) in the subscapularis repair group and 3 dislocations in the no-repair group (2.6%), which were not significantly different.ConclusionPrimary RTSAs with or without subscapularis repair have similar clinical outcome scores, range of motion, strength, and rates of complications including dislocations at 3 years of follow-up.
