1. A method for simulating prosthetic implant selection and placement in an anatomical structure using a computer-assisted surgery system, comprising the steps of:

  • generating a virtual model of the anatomical structure;

    registering the anatomical structure with the virtual model of the anatomical structure in the computer-assisted surgery system;

    determining a mechanical axis correction of the anatomical structure;

    inputting the mechanical axis correction into the computer-assisted surgery system;

    determining soft tissue balance in the anatomical structure;

    inputting the soft tissue balance into the computer-assisted surgery system;

    selecting a simulated implant component corresponding to the mechanical axis correction and the soft tissue balance;

    simulating implantation of the simulated implant component;

    verifying that the simulated implant component provides the mechanical axis correction and the soft tissue balance; and

    selecting an actual implant component corresponding to the simulated implant component if the simulated implant component provides the mechanical axis correction and the soft tissue balance.
