Abstract:
A device for attaching a tissue scaffold to bone tissue, comprising:a platform positionable in substantially parallel relationship to the bone tissue for retaining the tissue scaffold proximate to the bone tissue; a post extending from the platform, said post being insertable into a hole formed in the bone tissue; and at least one rib extending from a surface of said post along a portion of the length of said post from a first point distal to said platform to a second point intermediate said first point and said platform, said at least one rib having a cross-sectional area that increases along the length of said rib in the direction from said first point to said second point, said at least one rib establishing an interference fit relative to the hole in the bone tissue to prevent rotation of said device relative to the bone tissue, said at least one rib being shorter in length than the depth of the hole in the bone tissue and having a diverging surface which expands in width in the direction from said first point to said second point and which diverges from the surface of said post in the direction from said first point to said second point, and said at least one rib terminating proximate said second point in a sharp edge which is positionable within said hole for gripping the bone tissue to resist withdrawal of said device from the hole.
