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.
