Revision Reverse Total Shoulder Arthroplasty for Failed Anatomic Total Shoulder Arthroplasty With Massive Irreparable Rotator Cuff Tear.

Anatomic total shoulder arthroplasty (TSA) has become more common as surgical indications have expanded. However, the burden of revision shoulder arthroplasty has inevitably increased as well. Multiple studies have examined the use of reverse total shoulder arthroplasty (rTSA) as a revision option for failed anatomic TSA with a massive irreparable rotator cuff tear. Successful reconstruction of failed TSA with rTSA requires sufficient glenoid bone to place the glenoid segment, enough proximal humeral bone to allow for implantation of the humeral component, and sufficient tension in the soft-tissue envelope to ensure implant stability. In this article, we describe our preferred rTSA revision technique for the treatment of a failed TSA.
