Editorial Commentary: Biceps Rerouting Augmentation Technique Restores Biomechanics, Improves Healing, and Has Many Advantages for Repair of Large and Massive Rotator Cuff Tears

Abstract

The biceps rerouting (BR) augmentation technique has emerged as a useful option for the repair of rotator cuff tears when the torn tendon does not cover the footprint or can only be reduced under excessive tension. BR offers several advantages over traditional methods. It is an all-inside joint procedure, eliminating the need for skin incisions other than those for the arthroscopic portal, thus reducing operative time and infection risk. It does not lead to donor-site morbidity, unlike superior capsular reconstruction. In addition, the rerouted long head of the biceps tendon serves as a depressor of the humeral head and an internal splint, protecting cuff healing. Finally, it provides a biceps tenodesis such that biceps-related symptoms are prevented postoperatively. Clinical studies have shown the efficacy of the BR technique, particularly in achieving low rates of retear. Although the BR technique is a nonanatomic reconstruction, its biomechanical impact effectively restores joint function to a state similar to the original. Considering these findings, the BR technique represents a significant advancement in managing large to massive rotator cuff tears, given its straightforward application and ability to re-establish joint biomechanics.
