Subscapularis Repair During Reverse Total Shoulder Arthroplasty

Subscapularis Repair During Reverse Total Shoulder Arthroplasty: a Randomized Control Trial

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.

5. Fluent English speakers/readers

Exclusion Criteria:

1. Minor (<18 y/o)/vulnerable populations (pregnant women, prisoners, adults unable to consent)
2. Revision surgery
3. Oncologic surgery
4. non-ZB CRSS implants
5. Unrepairable SSc
