Abstract: A tendon anchor is used for attaching a tendon to a bone without sutures within a cylindrical bore drilled into the bone. The tendon anchor is adapted for insertion into the bore of a bone and has a generally elongated rectangular shape with opposite ends thereon. The tendon anchor has a transverse hole therein adapted to receive a central portion of the tendon and when the tendon anchor (with a tendon threaded into the hole therein) is inserted in the bore in the bone longitudinally, exerting force upon the ends of the tendon causes the tendon anchor to rotate to a partially transverse position within the bore thus forcing opposite end portions of the anchor into engagement with the cylindrical bore in the bone thereby securing the tendon in the bone.

Abstract: A tendon anchor is used for attaching a tendon to a bone without sutures within a bore drilled into the bone. A first elongated anchor member and a second elongated anchor member each have opposite ends and have an engaging portion on at least one end thereof which are adapted to engage into a cylindrical wall of the bore in the bone. The first and second members have a channel provided in one end thereof for receiving and holding a central portion of a tendon during insertion and when in final position in the bore in the bone, the first and second elongated members engage one another at a location intermediate the opposite ends thereof. The members are adapted to move relative to one another in a scissor like fashion when the members are inserted into the bore of the bone they are in a substantially closed scissor position with the central portion of the tendon engaged and held in the channel of each member.

Abstract: The present invention provides a tendon anchor for attaching a tendon to at least one bone without sutures within a bore drilled into at least one bone. The tendon anchor includes a first tendon anchor adapted for insertion into a bore of a first bone. The first tendon anchor has a channel provided therein for receiving and holding a central portion of a tendon during insertion and when in final position in the bore of the first bone. Opposite ends of the tendon extend out of the singular bore. A first securing mechanism (preferably a screw) which is associated with the first tendon anchor moves at least a part of the first tendon anchor radially outward to securely engage the first tendon anchor and the central portion of the tendon to the first bone by urging at least a part of the first tendon anchor against a cylindrical wall portion of said bore in said first bone. Thus, an anchor is provided without the need for sutures and the anchor may be inserted through a singular bore in the bone.

In many cases, a second tendon anchor will also be utilized to attach the tendon to two different bones.

Abstract: A patella replacement device has a generally hemispherical member which is surrounded by a collar or metallic ring and has apertures. A second hemispherical member has projections which fit into the apertures of the first member and the combination is used for the repair or replacement of the patella bone. At least one member is made of a high porosity metal material or contains a porous coating for initial stability through the adhesive and frictional properties of the metal material or coating.
