A modified suture-bridge technique for a marginal dog-ear deformity caused during rotator cuff repair.

Recently, the suture-bridge technique was found to maximize the utility of a single-row construct by using the suture limbs from the medial mattress sutures to bridge and compress the repaired tendon. However, the formation of marginal dog-ear deformities at a repaired rotator cuff is not uncommon with the suture-bridge technique. If a dog-ear deformity is observed at the margin after completion of the rotator cuff repair, the detached marginal cuff is pierced via a suture hook. One strand of the uncut suture in the lateral row is transported through the deformed cuff. A nonsliding knot is seated on top of the detached cuff and presses this area of soft tissue firmly onto the bone. If necessary, these steps are repeated for the other side of the detached rotator cuff. After completion of the rotator cuff repair, a "zigzag" pattern of compression of the cuff against the bone footprint without detachment of the rotator cuff is observed. After repair of the rotator cuff tear via the suture-bridge technique, the benefit of our simple technique for treating a marginal detached cuff is that the footprint contact area of the rotator cuff is restored completely, without the need for additional suture anchors.
