Cadaveric biomechanical study comparing three double-row repair techniques for delaminated rotator cuff tears: a medially knotted bridge, a knotless suture-tape bridge, and a novel knotless double-layer-specific repair that reconstructs the superior capsule and bursal tendon layer separately. Evaluates footprint contact area across shoulder positions, cyclic displacement, and load to failure in 18 fresh-frozen specimens.
When you encounter a delaminated rotator cuff tear intraoperatively — identifiable as a horizontal split between the articular-sided capsular layer and the bursal-sided tendon layer — consider addressing each layer independently rather than bundling them into a single en masse repair.
This study provides biomechanical evidence that layer-specific reconstruction more closely restores native footprint contact and tendon tension across the range of abduction used in early rehabilitation, without compromising fixation strength.
