1. A method of preparing a patient'"'"'s proximal tibia with a surgical saw and cutting instrumentation to receive a tibial implant comprising the steps of:

  • a) reaming the patient'"'"'s tibial intramedullary canal;

    b) placing a referencing member in the intramedullary canal;

    c) attaching a primary cutting instrument on the referencing member near the patient'"'"'s proximal tibia, the primary cutting instrument having transverse cutting guide surfaces for guiding the saw during a cutting of the proximal tibia and a stylus with an adjustable stylus member that can reference the proximal tibia before cutting begins;

    d) setting a depth of cut with the stylus;

    e) engaging the proximal tibial surface with the stylus;

    f) cutting the proximal tibia transversely with the saw by tracking the cutting guide surfaces with the saw;

    g) removing the first cutting instrument and its stylus;

    h) attaching a secondary cutting guide on the referencing member, said secondary cutting guide having a structural support member for cutting longitudinally into the proximal tibia; and

    i) making a secondary transverse cut on the proximal tibia using the secondary cutting instrument, to more precisely prepare the proximal tibia to receive the tibial implant.
