Reverse shoulder arthroplasty with an inverted-bearing prosthesis as revision procedure for failed anatomic and reverse shoulder arthroplasty: a long-term multicenter study.

We found better long-term clinical scores, abduction, and prosthesis survival rates after failed primary anatomic shoulder arthroplasty than after RTSA. Pain reduction and complication rates were comparable in both groups. Thus, anatomic shoulder arthroplasty remains an attractive option for primary arthroplasty in selected cases.
