<p>A suture buttress (14) comprises a hollow tube (26) having an outer wall (28), a central channel, a center line (44) extending through the channel, leading end (32) for insertion into a bone tunnel, and a trailing end. The hollow tube is bendable into a curved tube having an outer radius, and an outer radial surface, the outer radial surface defining a plurality of slits (40) formed in the outer wall. The suture buttress further includes at least one projecting member (240) integral with, an extending outward from the outer wall. The at least one projecting member is sufficiently strong to form a friction fit within a bone tunnel. A method for using the suture buttress to attach soft tissue to bone by inserting the suture buttress into a tunnel formed in bone, passing a suture through the tunnel and the suture buttress, and using the suture to attach soft tissue to the bone.</p> |
