Effect of prior rotator cuff repair on clinical outcomes following reverse shoulder arthroplasty

摘要

Background: Reverse shoulder arthroplasty (RSA) has been reported to improve pain and function in patients with cuff tear arthroplasty (CTA); massive rotator cuff tear and associated glenohumeral arthritis.1,2 For the potential complication or unclear long-term outcomes, however, surgeons might consider traditional rotator cuff repair as a salvage procedure. There has been limited information regarding the effect of prior rotator cuff repair on clinical outcomes after subsequent RSA in CTA patients. Therefore, the purpose of this study was to assess the outcomes of RSA in patients who had undergone previous rotator cuff repair compared with those who had not.
