"Transosseous-equivalent" rotator cuff repair technique.

Abstract

In order to optimize healing biology at a repaired rotator cuff footprint, we have developed a "transosseous-equivalent" rotator cuff repair that can be performed arthroscopically. What the arthroscopically repaired tendon experiences is "equivalent" to what is experienced with a traditional open suture-bridge technique. This repair maximizes the utility of a single-row repair technique by preserving the suture limbs of the medial single-row and bridging these sutures over the footprint insertion with distal-lateral interference screw suture fixation; the medial row uses a mattress suture configuration. The geometry of the construct compresses the tendon, optimizing tendon-to-tuberosity contact dimensions, while providing strength sufficient to withstand immediate postoperative rehabilitation.
