  • Patent number: 5683469
    Abstract: The method of implanting a femoral and a tibial knee prosthesis and instruments for surgically implanting the femoral and tibial prosthesis component as disclosed. The method includes the formation of a plurality of surgical cuts on the patient's distal femur. A trial tibial prosthesis is then fitted to the surgically prepared distal femur. The trial prosthesis has a femoral articulating surface and a non-articulating surface that fits the patient's distal femur at the surgical cuts. A surgeon then forms a transverse cut on the patient's proximal tibia. The surgeon places a tibial trial prosthesis on the patient's proximal tibia, the trial prosthesis including a tibial trial stem that fits the patient's intramedullary canal, a tibial trial metallic tray or plate, and a plastic trial insert that fits the tibial tray or plate. The plastic insert includes a tibial articulating surface that can articulate with the femoral articulating surface.

  • Patent number: 5667511
    Abstract: A method of preparing a patient's proximal tibia with a surgical saw and cutting instrumentation is disclosed. The method of the present invention prepares the patient's proximal tibial to receive a tibial implant. The patient's intramedullary canal is first reamed and then an intramedullary rod is placed in the intramedullary canal as a reference. A first cutting instrument is bound on the rod above the patient's proximal tibia. The first cutting instrument includes a stylus that is used to set the depth of cut by referencing the top of the proximal tibia. The proximal tibia is then transversely cut with the saw by tracking the first cutting guide surfaces with the saw. The first cutting instrument is removed together with its stylus. A secondary cutting instrument is then placed on the rod above the proximal tibia. The second cutting instrument has a cutter at its center for cutting longitudinally into the proximal tibia.
