1. A method of manufacturing an arthroplasty jig, the method comprising:

  • generating two-dimensional images of at least a portion of a bone forming a joint;

    using at least one computer processor to generate a first three-dimensional computer model of the at least a portion of the bone from the two-dimensional images;

    using at least one computer processor to generate a second three-dimensional computer model of the at least a portion of the bone from the two-dimensional images;

    causing the first and second three-dimensional computer models to have in common a reference position, wherein the reference position includes at least one of a location or an orientation relative to an origin;

    generating a first type of data with the first three-dimensional computer model,wherein the first three-dimensional computer model is a bone only model;

    generating a second type of data with the second three-dimensional computer model, wherein the second three-dimensional computer model is a bone and cartilage model;

    employing the reference position to integrate the first and second types of data into an integrated jig data; and

    using the integrated jig data at a manufacturing machine to manufacture the arthroplasty jig.
