Arthroscopic single-row rotator cuff repair is a well established surgical technique for the treatment of rotator cuff tears. However, the problem of postoperative retear remains a concern. Various avenues are being explored to address this problem. Some studies have suggested that restoring the anatomical footprint may improve the healing and initial strength of the repaired rotator cuff tendon. The double-row technique was introduced as a method of reconstructing the anatomical footprint. According to biomechanical studies on cadavers, this technique improved mechanical strength and reduced gap formation. However, the biological properties of reattached tendon such as tension, and vascularity have not been proved yet. Furthermore, the apparent mechanical superiority of the double-row over the single-row construction has not resulted in better functional outcomes. Therefore, the less complicated and less costly single-row technique is still the recommended treatment for rotator cuff repairs.
