Mini-open Versus Arthroscopic Rotator Cuff Repair: A Comparison of Clinical Results and Re-tear Rates by Magnetic Resonance Arthrogram

Abstract

Aim:The aim of this study was to compare the re-tear rates and clinical results between mini-open and full arthroscopic techniques of the rotator cuff repair.Methods:We retrospectively reviewed a total of 82 patients. Mini-open and full arthroscopic techniques were performed in 30 patients (group MO) and 52 patients (group A), respectively. The main outcome measurements were the University of California at Los Angeles (UCLA) and American Shoulder and Elbow Surgeons (ASES) scores, abduction and external rotation strengths (kg), and re-tear rate on magnetic resonance arthrography. All variables were compared between the groups.Results:The mean age of all patients included in the study was 55.4±6.1 years. Sixty (73.2%) patients were female. The mean follow-up was 12.3±1.4 months. The mean UCLA and ASES scores and external rotation strength in group A were significantly higher than in group MO. The mean abduction strengths were similar. There was no statistically significant difference in terms of re-tear rates.Conclusion:Rotator cuff tears can be successfully treated with either mini-open or arthroscopic techniques. Although there was no statistically significant difference in re-tear rates, full arthroscopic repair had better functional outcomes.
