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.

To complete reverse total shoulder arthroplasty, the surgeon must cut through the subscapularis muscle. In this arm of the study, the muscle will be repaired, rather than left to heal itself.

The American Shoulder and Elbow Surgeons (ASES) Shoulder Score
Scored from 0 (worst shoulder condition) to 100 (best shoulder condition)
Time frame: up to 12 months post-surgery
Internal Rotator (IR) Strength
IR at the side and supported IR at 90˚ scapation; percent of nonsurgical side
Time frame: up to 12 months post-surgery
PROMIS Bank v1.1 - Pain Interference
PROMIS measures generate T-scores. T-scores are standard scores with a mean of 50 and standard deviation of 10 in a reference population (usually U.S. general population).
Time frame: up to 12 months post-surgery
Shoulder Range of Motion
shoulder extension, flexion, internal rotation, abduction, adduction; percent of nonsurgical side
Time frame: up to 12 months post-surgery
