A reverse total shoulder arthroplasty (rTSA) is specifically designed for patients with marked instability of the glenohumeral joint and a rotator cuff that is not repairable. Hemiarthroplasty may be performed arthroscopically, but it is not the most common approach. The primary indication for glenohumeral arthroplasty is pain and/or loss of function, not limited mobility alone. To expose the joint during surgery, the subscapularis muscle is typically released, not the anterior deltoid.
