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.
