Study Summary

This multi-site study involving Northwestern Medicine, Beaumont Health, and Loyola Medicine seeks to answer the following question: do patients who undergo subscapularis (SSc) repair during reverse total shoulder arthroplasty (RSA) have better post-operative outcomes than patients who do not undergo SSc repair during RSA? The investigators hypothesize that patients who do not undergo SSc repair during RSA have better post-operative outcomes than patients who undergo SSc repair during RSA. This study will address the controversy surrounding SSc repair during RSA via a multi-institutional randomized controlled trial that will compare clinical outcomes of patients who receive SSc repair during RSA to those who do not.
