Purpose/Hypothesis: The purpose of this study was to compare the outcomes and effectiveness of partial rotator cuff repair with SCR using the long head of the biceps tendon (PRCR-SCRB) and SCR with a tensor fasciae latae autograft (SCRTF) for the treatment of rotator cuff tears with severe fatty degeneration. The hypothesis of this study was that SCRTF would be superior to PRCR-SCRB in functional and anatomic outcomes. Study Design: Cohort studyLevel of evidence, 3. Methods: A total of 26 consecutive patients with massive and fatty degenerative rotator cuff tears were treated surgically. Patients were divided into either the PRCR-SCRB group (n = 14) or SCRTF group (n = 12). Functional outcomes were assessed at final follow-up, and the acromiohumeral distance (AHD) was measured. Results: All functional scores significantly improved in both groups at final follow-up. The PRCR-SCRB group showed better overall outcomes in terms of the visual analog scale for painAmerican Shoulder and Elbow Surgeons scoreand Quick Disabilities of the Arm, Shoulder and Hand, but these differences were not statistically significant. Better outcomes were found for only the AHD for the PRCR-SCRB group without statistical significance (P = .4). No statistical difference was found in terms of retear rate. Conclusion: PRCR-SCRB had comparable outcomes and improvement in AHD compared with SCRTF without the need for additional graft harvesting.massive rotator cuff tearfatty degenerationsuperior capsular reconstructiontensor fasciae lataelong head of the biceps tendonrotator cuff repairArticleWOS:000540562300001
