A method and system for the creation or modification of the wear surface of orthopedic joints, involving the preparation and use of one or more partially or fully preformed components adapted for insertion and placement into the body and at the joint site. The system includes a method and related components and/or devices in the form of a kit that can be used to provide or perform some or all of the steps of: a) preparing a joint to receive an implant, b) determining an appropriate implant size for a particular joint, c) determining an appropriate implant thickness, d) inserting the implant into the joint, and/or e) securing the implant within the joint to a desired extent. One or more of the various components and devices, including optionally one or more implants themselves, can be provided or packaged separately or in varying desired combinations and subcombinations to provide a kit of this invention. In turn, a kit can include, or be used in combination with, one or more corresponding devices or components that will already exist in the surgical suite, and that can optionally be sterilized for re-use in subsequent procedures. The selection and use of components, devices and/or implants within a kit of this invention is facilitated by the coordination of various features in the manner described, including appearance, size and configuration.

606089000

A method and system for preparing a bone surface, as by smoothing the surface, in preparation for contacting and/or receiving a prosthetic implant. The smoothing system and method are particularly well suited for use with articulating joints, in which a polymeric biomaterial such as polyurethane is implanted and retained upon one (supporting) bone surface, in order to provide a corresponding surface for opposing, articulating bone. Smoothing condylar bone, for instance, can significantly decrease the friction between a the condylar surface, and particularly one that is itself diseased or damaged, and to remove osteophytes and entheseophytes.

The invention includes an interpositional arthrosplasty implant adapted to be retained in position in apposition to ajoint surface, at least in part, by surrounding healthy tissue. In some embodiments the implant comprises a knee implant. The implant can include one or more structural features adapted to be fixedly positioned within and/or in apposition to the natural meniscus.
