Abstract
Disclosed herein is a method of generating a computerized bone model representative of at least a portion of a patient bone in a pre-degenerated state. The method includes: generating at least one image of the patient bone in a degenerated state; identifying a reference portion associated with a generally non-degenerated portion of the patient bone; identifying a degenerated portion associated with a generally degenerated portion of the patient bone; and using information from at least one image associated with the reference portion to modify at least one aspect associated with at least one image associated the generally degenerated portion. The method may further include employing the computerized bone model representative of the at least a portion of the patient bone in the pre-degenerated state in defining manufacturing instructions for the manufacture of a customized arthroplasty jig. Also disclosed herein is a customized arthroplasty jig manufactured according to the above-described method. The customized arthroplasty jig is configured to facilitate a prosthetic implant restoring a patient joint to a natural alignment. The prosthetic implant may be for a total joint replacement or partial joint replacement. The patient joint may be a variety of joints, including, but not limited to, a knee joint.
