Frank RM, et al. - All-suture suture anchors (ASSAs) was compared with conventional interference screws (CISs) and conventional suture anchors (CSAs) for long head of the biceps tendon fixation during proximal biceps tenodesis (BT), in terms of biomechanical properties. Twenty-one fresh-frozen human cadaveric shoulders were randomized into 3 subpectoral BT treatment groups: ASSA, CSA, and CIS. Researchers cyclically loaded each construct from 5 to 70 N for 500 cycles (1 Hz). Specimens surviving cyclic loading were then pulled to failure (1 mm/s). Removing tissues, the humerus was subjected to torsional displacement at a rate of 1°/s until fracture occurred. ASSA, CSA, and CIS constructs showed similar biomechanical properties. They noted lower tendon elongation at maximum load but with several early failures in the interference screw group compared with the suture anchor groups. Maximum tendon and torsional bone loads similar to interference screws was noted when suture anchors were used for the long head of the biceps tendon. In all of the specimens, torsional testing of the CIS led to spiral fractures traversing the screw tunnel, this was not observed in the suture anchor groups.
