1. A method of determining a position for a joint implant, the method comprising:

  • generating a function based on patient specific data comprising locational data for one or more patient bones associated with the joint, and a plurality of flexion points, each flexion point corresponding to a positional angle of the joint;

    receiving an initial parameter set for placing the joint implant, wherein the initial parameter set comprises a plurality of parameters;

    applying the function to the initial parameter set to determine an initial result, comprising calculating at least one of a gap distance and an overlap distance for each of the flexion points based on the initial parameter set;

    generating a plurality of candidate parameter sets for placing the joint implant, wherein each of the plurality of candidate parameter sets comprises the initial parameter set with a changed value for at least one of the plurality of parameters;

    applying the function to each of the candidate parameter sets to determine a candidate result, comprising calculating at least one of a gap distance and an overlap distance for each of the flexion points based on the candidate parameter set;

    ranking the plurality of candidate parameter sets and the initial parameter set based on the associated candidate results and initial result;

    selecting a parameter set from the plurality of candidate sets and the initial parameter set having a highest ranked result; and

    generating a surgical plan for placing the joint implant based on the selected parameter set.
