Abstract Surgical management for biceps pathologies has advanced to provide stronger fixation and to be less invasive. The long head of the biceps tendon has been recognized as a common contributor to anterior shoulder pain and is often associated with other glenohumeral pathologies such as SLAP lesions, rotator cuff tears, and subacromial impingement. Both tenotomy and tenodesis have shown to be effective in ameliorating pain associated with the long head of the biceps tendon. However, decreased muscle function and cosmetic concerns are seen at higher rates after tenotomy compared with tenodesis. One option for the treatment of biceps tendon pathology includes mini‐open subpectoral biceps tenodesis. Lower reoperation rates are observed after subpectoral biceps tenodesis than after suprapectoral biceps tenodesis, with thoughts that releasing the tendon from its sheath and the bicipital groove relieves the patient of most associated pain. The purpose of this Technical Note is to describe in detail our preferred operative technique for mini‐open subpectoral biceps tenodesis using an onlay technique with all‐suture anchor fixation.
