Arthroscopic rotator cuff repair: scientific rationale, surgical technique, and early clinical and functional results of a knotless self-reinforcing double-row rotator cuff repair system.
BACKGROUND
Rotator cuff repair has shown to improve shoulder function and reduce pain experienced by patients. Successful repairs should have high fixation strength, allow minimal gap formation, maintain stability, and restore normal anatomy and function of the supraspinatus footprint. The purpose of this study is to describe our preferred method for rotator cuff repair using a knotless self-reinforcing double-row system, and to cite biomechanical data rationalizing its use.


METHODS
Seventeen of 22 patients were identified as undergoing primary rotator cuff repair with minimum follow-up of 1 year (mean, 535 days; range, 370-939). The average age was 63 (range, 43-79). Data collected included average pain today, average worst pain, Single Assessment Numeric Evaluation (SANE), and patient satisfaction.


RESULTS
For all patients, average pain today and average worst pain decreased and functional scores (SANE) increased. Patient satisfaction was 9.8 out of 10 (range, 7-9). The patients also began rehabilitation earlier and returned to full activities at 4 months.


CONCLUSIONS
These results indicate that the knotless self-reinforcing double-row repair system is a viable option in treating rotator cuff tears. This system provides improved contact area and restores the native footprint of the tendon leading to better outcomes.
