RecruitingProcedureComparison of Partial Rotator Cuff Repair vs. Superior Capsular Reconstruction for Irreparable Rotator Cuff TearsThe primary objective of this prospective randomized controlled trial is to compare pain and functional outcomes between two surgical modalities for irreparable rotator cuff tears as measured by the pain visual analog scale (VAS), simple shoulder test (SST), American Shoulder and Elbow Surgery shoulder score (ASES), and Patient Reported Outcomes Measurement Information System (PROMIS) 29 score at 6 weeks, 3, 6, 12, and 24 months post-operatively. The two surgical modalities of interest are partial rotator cuff repair alone and partial rotator cuff repair with superior capsule reconstruction (SCR). The secondary objective of this study is determine the failure rate of partial repair alone vs. partial repair with SCR via magnetic resonance imaging (MRI) at 12 months post-operatively. The information gained from this investigation will be useful to discern if SCR provides any benefit to patients with irreparable rotator cuff tears. The investigators hypothesize that there is no statistically significant difference in pain and functional outcomes between partial rotator cuff repair alone versus partial rotator cuff repair with SCR. In addition, the investigators hypothesize that the failure rate will be significantly higher in patients undergoing partial rotator cuff repair with SCR.
