1. A method of generating resection plane data for use in planning an arthroplasty procedure on a patient bone, the method comprising:

  • obtaining patient data associated with at least a portion of the patient bone, the patient data captured using a medical imaging machine;

    generating a three-dimensional patient bone model from the patient data, the patient bone model comprising a polygonal surface mesh;

    identifying a location of a posterior point on the polygonal surface mesh;

    creating a three-dimensional shape centered at or near the location;

    identifying a most posterior vertex of all vertices of the polygonal surface mesh that are enclosed by the three-dimensional shape;

    using the most posterior vertex as a factor for determining a posterior resection depth; and

    generating resection data using the posterior resection depth, the resection data configured to be utilized by a navigation system during the arthroplasty procedure.
