Purpose To provide an updated comparison between modern arthroscopic and mini-open repairs for treating rotator cuff tears. Methods Multiple online databases were searched from 2010 to October 1st, 2020. A meta-analysis was conducted for patient-reported outcomes and complications. Results Eleven studies were included. Majority of patients underwent mini-open repair (MOR) compared to arthroscopic repair (AR) (57.4% vs 42.6%). A meta-analysis found statistically significant differences (p < 0.05) in patient-reported outcomes favouring AR. While retear rates were higher in AR (p = 0.03) analysis of retear rates for arthroscopic double row and mini-open repairs, yielded no differences between groups (p = 0.48). Conclusion Patients undergoing AR for rotator cuff tears had improved post-operative clinical outcomes in some functional outcomes compared to MOR. Modern arthroscopic double row repair result in similar failure rates to open repair techniques. Level of evidence Level III, Systematic Review of Level I-III studies.
