Abstract:
Systems for joint arthroplasty include prostheses which are secured to bone with sliding anchors. Examples include unicondylar and bicondylar knee prostheses for hemi-arthroplasty and total arthroplasty. Instruments guide the anchors into proper engagement with the prosthetic components. Methods of using the prostheses and instruments are disclosed.

Claim (Index 1):
A joint arthroplasty system, comprising:\n a prosthetic articular surface which replaces at least a portion of a natural articular surface of a bone; a prosthetic component comprising a bone-contacting surface, the bone-contacting surface comprising at least one undercut channel extending across at least a portion of the bone-contacting surface and through a perimeter edge of the bone-contacting surface; and an anchor comprising a rail, a blade, and a support, the rail comprising at least one lateral protrusion, the blade offset from the rail, the support connecting the rail and the blade; wherein the rail is insertable into the channel to connect the anchor to the prosthetic component; wherein, when the rail is inserted into the channel, the support protrudes through the bone-contacting surface, and the blade is carried at a distance from the bone-contacting surface, characterized in that the lateral protrusion is adapted such that, when the rail is inserted into the channel, the lateral protrusion plastically deforms to create an interference fit in the channel.
