Rotator cuff repair is performed commonly to address pain and shoulder dysfunction after a rotator cuff tear. Recurrent or persistent tears are common after rotator cuff repair. The causes of failed rotator cuff surgery include biologic factors, technical errors, and traumatic failure. A thorough history, physical examination, and appropriate imaging are required to determine if a patient is an appropriate candidate for revision rotator cuff repair. Ideal candidates for revision rotator cuff repair are younger, have minimal muscle atrophy, minimal tendon retraction, preoperative forward elevation of greater than 90°, a functioning deltoid, and no evidence of cuff tear arthropathy.
