Comparing tendon repair options during reverse shoulder replacement
Official title: Subscapularis Repair in Reverse Shoulder Arthroplasty: A Multi-Center Randomized Single Blinded Superiority Study
Run by University of Maryland, Baltimore · NCT05344898 · Data updated 2026-11-12
This study tests whether repairing a specific shoulder tendon during reverse shoulder replacement can help patients move their arm better and reduce the chance of dislocation.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 to 95 who are scheduled for reverse shoulder arthroplasty.
✕Probably not a fit
Patients with irreparable subscapularis tendons or a history of proximal humerus fractures may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates the outcomes of repairing the subscapularis tendon versus not repairing it during reverse shoulder arthroplasty. The research aims to determine if tendon repair can reduce the risk of dislocation and improve arm movement after surgery. A total of 148 patients will be enrolled, and they will be randomly assigned to either the repair or no repair group. The study will track functionality and complications over a duration of five years to provide insights into the best surgical approach.
Why it matters
Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced complications for patients undergoing reverse shoulder replacement.
How similar studies have gone: While there is ongoing debate regarding tendon repair in shoulder surgeries, this specific approach is novel and has not been extensively tested in prior studies.
