The skin is incised 1 to 2 cm distal to the lateral portal. A transosseous tunnel is created through the greater tuberosity by a sharp penetrator, entering 1.5 to 2 cm distal to the top of the greater tuberosity. The penetrator exits medially, between the tip of the greater tuberosity and the articular surface of the humeral head, in the middle of the footprint. The first anchor, a 5-mm Spiralok (DePuy Mitek, Norwood, MA) is placed at the penetrator's exit site on the footprint. Using a specially designed suture leader, the lateral limb of the suture in the anchor, which passes through the previously created transosseous tunnel, is taken from the anchor and pulled out. The other suture end is passed through the supraspinatus tendon. The second suture, placed superficially in the anchor, is passed from the anchor through the supraspinatus tendon, as a mattress suture. If more anchors are required, the procedure should be repeated. The transosseous suture limb and the suture limb that is passed through the supraspinatus tendon are tied through the lateral portal. The knot tying is then performed with a sliding Delimar knot. The mattress suture, passing through the supraspinatus tendon, is tied through the anterior lateral portal. The knot tying procedure is repeated depending on the number of anchors.
