Subpectoral Biceps Tenodesis Using the TensionTight™ Button. With the TensionTight™ button, perform a knotless onlay biceps tenodesis using an arthroscopic suprapectoral or open subpectoral approach. The button’s locking jaw lets the suture slide easily in one direction to reduce the tendon to the bone while locking in the opposite direction to secure the tendon against the humerus. | Mix Dancing Events
