BACKGROUND: The purpose of this study was to compare latissimus dorsi tendon transfer (LDTT) and arthroscopic superior capsular reconstruction (SCR) to determine if one is superior to the other regarding improvement in range of motion (ROM) or patient-reported outcomes (PROs). METHODS: A multicenter, retrospective cohort study was conducted on 43 patients with an irreparable, posterosuperior rotator cuff tear who underwent either LDTT or SCR. Preoperative and postoperative forward flexion and external rotation, as well as PROs including ASES, VAS, and SSV, were assessed. Student t-test and chi-square statistical analyses were performed. RESULTS: 16 LDTT, at mean follow-up of 18 months, and 27 SCR, at mean follow-up 15 months, were studied. Mean active forward flexion significantly improved from 85.2° to 137.6° in the SCR cohort (P=0.001). SCR patients demonstrated a significantly greater increase in forward flexion as compared to LDTT patients (52.4° vs 14.1°, P=0.001). Mean active external rotation amongst the LDTT group significantly improved from 41.7° to 61.5° (P=0.032). LDTT demonstrated significantly greater improvement in external rotation as compared to SCR (19.4° vs 0.8°, P=0.011). There were no significant differences in reported ASES, VAS, or SSV scores. CONCLUSION: This study demonstrates successful clinical and patient-reported outcomes with both LDTT and SCR for irreparable, posterosuperior rotator cuff tears, with greater improvement in forward flexion with SCR and greater improvement in external rotation with LDTT.
