BACKGROUND Biomechanical testing without humeral motion is a standard method for evaluating rotator cuff repair constructs. This cannot elucidate the effects of dynamic external rotation on the repair, which is a common postoperative motion. HYPOTHESIS Biomechanical properties and gap formation of rotator cuff repairs will be different when dynamic external rotation is allowed to occur during loading. STUDY DESIGN Controlled laboratory study. METHODS In 6 matched pairs of human cadaveric… CONTINUE READING
