Abstract: A method for planning an arthroplasty procedure on a patient bone. The method may include accessing generic bone data stored in a memory of a computer, using the computer to generate modified bone data by modifying the generic bone data according to medical imaging data of the patient bone, using the computer to derive a location of non-bone tissue data relative to the modified bone data, and superimposing implant data and the modified bone data in defining a resection of an arthroplasty target region of the patient bone.

Abstract: A method of performing an arthroplasty procedure on a knee region of a femur of a patient where an implant is implanted on the knee region of the femur as part of the arthroplasty procedure is disclosed herein. The method may include generating a planned postoperative positional relationship of the implant relative to the femur. The method may also include, with the computerized representation of the implant in the planned postoperative positional relationship with the computerized representation of the knee region of the femur, generating a planned resection of the femur that will facilitate the implant being implanted on the knee region of the femur in the planned postoperative positional relationship. And the method may also include guiding an actual resection of the femur according to the planned resection of the femur.

Abstract: A method of manufacturing an arthroplasty jig is disclosed herein. The method may include the following: generate two dimensional image data of a patient joint to undergo arthroplasty, identify in the two dimensional image data a first point corresponding to an articular surface of a bone forming the joint, identify a second point corresponding to an articular surface of an implant, identify a location of a resection plane when the first point is correlated with the second point, and create the arthroplasty jig with a resection guide located according to the identified location of the resection plane.
