Background: The purpose of this study was to investigate the prevalence, epidemiology, and outcomes of anterosuperior (A group) rotator cuff tears (RCTs) and posterosuperior (P group) RCTs treated by arthroscopic rotator cuff repair (ARCR).
Methods: A total of 67 A group patients and 14 P group patients were included in the study.
Results: The prevalence of the A group (82.3%) was significantly higher than that of the P group (17.7%).
Conclusion: The outcomes in both groups were good, even though the A group had a higher rate of injury to the LHB than the P group.
Level of evidence: Level III, case-control Study, treatment study.
