The double-pulley technique for double-row rotator cuff repair.
In an effort to maximize the area of footprint coverage, we developed the "double-pulley technique" for double-row rotator cuff repairs. Two suture anchors are inserted at the articular margin of the greater tuberosity (one anterior and one posterior). All 4 suture strands from each anchor are passed through a single medial point on the torn cuff. In this way, the 4 suture strands from the anteromedial anchor pass through 1 point in the cuff and the 4 strands from the posteromedial anchor pass through a different point in the cuff. A suture strand from 1 anchor is tied extracorporeally to a suture strand of the same color from the other anchor. The other ends of those 2 strands are then pulled, thereby delivering this extracorporeal knot into the joint and over the medial footprint. These 2 free suture strands are then tied together as a static knot. The procedure is repeated with the other sutures. This technique creates a double mattress suture medially, which compresses the intervening tendon bridge against its bone bed. We call this procedure the double-pulley technique because it uses the anchor eyelets as pulleys to deliver the extracorporeal knot into the shoulder. After the lateral row repair is performed, the rotator cuff footprint will be completely reconstituted.
