    摘要： A surgical method and device are provided which enable to prepare a natural patella for accepting a patella implant, while preserving a predetermined thickness of the natural patella. The device comprises: (a) a bone shaping element such as a reamer or a miller, including: (i) a rotatable bone shaping member having a lower edge; (ii) a shaft member having a scale including at least one marker; and (b) a guiding device for guiding the bone shaping element, including: (i) a patella holder for holding the natural patella; (ii) a pointer positioned at a constant distant from the patella holder for pointing at the marker, such that the distance between the pointer and the patella holder equals the sum of: the distance between the marker and the lower edge of the bone shaping member; and the preserved thickness of the natural patella. The method comprises: (a) holding the natural patella by means of a patella holder; (b) shaping the natural patella by means of a bone shaping element, the bone shaping element having: a marker; and a lower edge; (c) monitoring the shaping by means of a pointer, the distance between the pointer and the patella holder being equal to the sum of: (i) the distance between the marker and the lower edge; and (ii) the preserved thickness of the natural patella, such that when the marker merges with the pointer, a conclusion is made that the preserved thickness of the natural patella equals the predetermined value.

    摘要： A surgical method and tool for repairing a natural patella are provided. The method comprises the steps of: (a) preparing a natural patella by removing a portion thereof so as to leave a substantially convex remaining portion; and (b) fixing a patella implant onto the substantially convex remaining portion of the natural patella, the patella implant including: an upper surface for sliding over the femoral articulating member; a substantially concave under surface for fixation to the convex remaining portion of the natural patella; and a circumferential facet. A surgical tool according to the present invention comprises a substantially concave rotatable reaming member, the concavity of the reaming member being substantially equal to the concavity of the undersurface of the patella implant. The reaming member features a bit for drilling a hole in the natural patella so as to accept a peg connected to the patella implant. Alternatively, the bit may be used for guiding the reaming member through a central pre-drilled hole in the natural patella.

    摘要： A patella (knee cap) implant for fixation to the remaining portion of a natural patella and for sliding over a femoral articulating member, the implant including an upper surface, typically convex, for sliding over the femoral articulating member, typically a groove, and a concave undersurface for fixation to the remaining portion of the natural patella. Also provided is a tool for preparing the natural patella to accept a patella implant and a method for surgically fixing the patella implant.
