Abstract
Controversy exists regarding the optimal technique for arthroscopic rotator cuff repair. No previous comparative trials have reported on the long-term follow-up of single and double row fixation in arthroscopic cuff repair. The purpose of this study was to compare the long-term functional outcomes of single-row and double-row suture techniques for repair of the rotator cuff 10-years post-operatively.
Ninety patients undergoing arthroscopic rotator cuff repair were randomized to receive either single-row or double-row repair. The primary objective was to compare the Western Ontario Rotator Cuff Index (WORC) score 10-years post-operatively. Secondary objectives included comparison of the Constant, and American Shoulder and Elbow Surgeons (ASES) scores and supraspinatus strength between groups. Out of 90 patients originally randomized, 57 returned for the long-term 10-year follow-up.
Baseline demographic data did not differ between groups. The WORC score was not significantly different between groups at long-term follow-up (p=0.13). No statistical differences were observed between groups for the Constant (p=0.51), ASES (p=0.48) scores, or strength scores (p=0.93). A significant improvement was observed between pre-operative and the final 10-year follow-up. There were no differences observed in all outcomes between two and 10-years post-operatively.
No statistically significant differences in functional or quality of life outcomes were identified between single-row and double-row fixation techniques at long-term follow-up.
