Abstract The proximal biceps tendon is a common source of shoulder pain and dysfunction. When patients continue to have pain after exhaustive nonoperative treatment, the long head of the biceps tendon can be effectively treated with a tenotomy or tenodesis. Although biceps tenotomy is a less complex and highly reliable treatment, there is the potential for suboptimal outcomes including muscle cramping, fatigue, cosmetic deformity, and supination weakness. Biceps tenodesis eliminates the source of shoulder pain while securing the tendon proximally. Currently, there are multiple techniques for performing a biceps tenodesis (arthroscopic, open suprapectoral, open subpectoral) and myriad fixation methods (bio‐tenodesis screw, bone bridge, cortical button, all‐suture anchor). Our article presents a technique for a mini‐open subpectoral biceps tenodesis using an onlay technique with an all‐suture anchor preloaded with needles. This technique allows efficient and proper tendon fixation while minimizing potential complications.
