Reverse total shoulder arthroplasty after failed rotator cuff surgery.
BACKGROUND
The purpose is to report the results of reverse shoulder arthroplasty (RSA) after previous failed rotator cuff surgery.


METHODS
A retrospective multicenter study of 42 RSA in 40 patients (mean age, 71 years) with a mean follow-up of 50 months. Thirty shoulders presented with a pseudoparalytic shoulder and 12 with a painful shoulder with maintained active anterior elevation (AAE >or= 90 degrees).


RESULTS
Five complications (12%) occurred and 2 patients (5%) underwent re-operation. In pseudoparalytic shoulders, AAE increased from 56 degrees to 123 degrees and 7% were disappointed or dissatisfied. In painful shoulders, AAE decreased from 146 degrees to 122 degrees and 27% were disappointed or dissatisfied.


CONCLUSIONS
RSA can improve function in patients with cuff deficient shoulders after failure of previous cuff surgery. However, results are inferior to primary RSA. RSA when the patient maintains greater than 90 degrees of preoperative AAE risks loss of AAE and lower patient satisfaction.
