  • Patent number: 8486074
    Abstract: The invention is directed toward a surgical kit having component parts capable of use to prepare a cartilage implant plug from allograft condyle. The kit comprises a sizing gauge used to measure surface of the allograft condyle so that a cartilage implant plug can be removed that corresponds to the contours of the defect site excised on a patient. An adjustable guide member is mounted in a fixed orientation over the allograft condyle in which a cylindrical graft cutter for cutting a cylindrical allograft bone plug having a cartilage cap and a bone end portion. A chamfering tool is used for chamfering the bone end of the allograft bone plug.

  • Patent number: 8152846
    Abstract: The invention is directed toward a method and instrumentation to replace a damaged human knee joint meniscus with an allograft meniscus. The implant has its bone base cut to a desired width in a workstation. The finished base is measured in the sizing groove of the sizing block for width and length. The tibia is then drilled with drill to the appropriate depth and length and groove is formed in the tibia with a tissue chisel so that the width is the same as the width of the bone base. The bone base is press fit into the tibia groove and may be secured with a bone screw.

  • Patent number: 8152808
    Abstract: The invention is directed toward a surgical kit having component parts capable of use in excising a cartilage defect site on a patient to prepare the same for receipt of an implant plug, the kit comprising a cylindrical gauge with a central bore used to measure the defect area, a guide rod adapted to be driven through the gauge tube into the center of said defect area and a cartilage cutting assembly adapted to be mounted over the guide rod and used for excising the defect area and cutting a cylindrical bore into the defect area. The method for use of the kit comprises the steps of: marking the defect area to be cut; placing a guide rod into the center defect area and driving the same to a predetermined distance to secure the same in the defect area and placing a drill bit over the guide rod and rotating the drill bit to cut a cylindrical blind bore removing the cartilage defect.
