Reverse shoulder arthroplasty in the revision setting

Recent years have seen a rise in the popularity of reverse shoulder arthroplasty (rTSA). Over the past decade, changes in rTSA design have led to improvements in functional outcomes and implant survival as well as fewer complications. While traditionally indicated for the management of rotator cuff tear arthropathy, rTSA has emerged as a versatile revision option following failure of a primary procedure including failed shoulder arthroplasty, rotator cuff repair, or proximal humerus open reduction and internal fixation. A large body of literature has demonstrated the success of rTSA following these procedures. The purpose of this article is to review the outcomes of rTSA in the revision setting, compare them with outcomes of primary rTSA, and provide guidance to surgeons on how to use this option for a failed primary procedure.
