1. A method suitable for analyzing surgical techniques, said method comprising:

  • a. generating three-dimensional computer models of orthopedic devices, said devices selected from the group of orthopedic instruments and implants, wherein data corresponding to said models is stored in a memory system of a computer;

    b. generating three-dimensional models of a targeted surgical site on a body portion based upon tomographic data stored in the memory system for the surgical site;

    c. inputting into said memory select target values corresponding to one or more measurable technical parameters associated with said surgical procedure, said parameters selected from the group consisting of three-dimensional positioning and dimensions of bones, three-dimensional positioning and dimensions of soft tissue structures, three-dimensional positioning and dimensions of said orthopedic devices for surgery, and predicted values corresponding to range and forces associated with physiologic joint motion and joint laxity;

    d. attaching one or more tracking devices to said body near said target surgical site, said tracking devices operatively in communication with said computer system;

    e. performing a surgical procedure on said target surgical site;

    f. communicating tracking data generated during said surgical procedure to said computer system;

    g. calculating actual values based upon said tracking data, said actual values corresponding to said technical parameters set for the surgical procedure; and

    h. comparing said target values and said actual values of said technical parameters after performing said surgical procedure.
