Claim:
1. A method of manufacturing an arthroplasty jig configured to facilitate an arthroplasty procedure on a femur of a patient, the method comprising: a) generating via at least one computer a three dimensional computer bone model from medical images of at least a distal region of the femur, wherein the three dimensional computer bone model represents at least a non-resected portion of the at least a distal region of the femur; b) preoperatively planning the arthroplasty procedure via the at least one computer, wherein the preoperative planning plans a postoperative position and alignment of an implant of the arthroplasty procedure, the preoperative planning comprising: superimposing a representation of the implant and the three dimensional computer bone model; c) generating via the at least one computer a production file based upon the preoperative planning of step b), wherein the production file comprises instructions to create the arthroplasty jig to comprise a mating surface and a cutting instrument guide, wherein the mating surface comprises a surface profile that matches a surface profile of the at least a non-resected portion of the at least a distal region of the femur, the cutting instrument guide corresponds to a distal femoral resection plane, and the arthroplasty jig is configured such that, when the mating surface matingly engages the at least a non-resected portion of the at least a distal region of the femur in a single relative position, the cutting instrument guide is oriented to facilitate a bone resection in the at least a distal region of the femur that is perpendicular to a preoperatively selected axis associated with the femur; and d) causing a manufacturing device to employ the production file and manufacture the arthroplasty jig.
