1. A method for attaching a rotator cuff to a humerus, said method comprising:
- forming a plurality of bone tunnels through the humerus, each having an entrance opening and an exit opening;
positioning the rotator cuff atop the humerus adjacent to the entrance openings of the bone tunnels;
providing a first rotator cuff buttress plate defining a plurality of apertures passing therethrough;
positioning the first rotator cuff buttress plate adjacent to the exit openings of the bone tunnels;
passing a suture through the rotator cuff, a first bone tunnel and a first aperture in the first buttress plate;
providing a second buttress plate positioned atop the rotator cuff and passing the suture through the second buttress plate; and
securing the suture relative to the rotator cuff and the first and second buttress plates.

Abstract
A rotator cuff buttress plate adapted to support a load from at least one suture used in securing a rotator cuff relative to a humerus. The rotator cuff buttress plate includes an inner surface, an outer surface, a sidewall and a plurality of apertures. The inner surface is adapted to engage an outer portion of a humerus. The outer surface is opposite the inner surface and is adapted to support the load from at least one suture. The sidewall is positioned between the inner surface and the outer surface. The suture is passed through the at least one aperture to distribute the suture load over the buttress plate.
