1. A computer-implemented method of improving a patello-femoral response, the method comprising:
characterizing an anterior geometry of a patella by:
receiving, by a probe tracking system, a plurality of locations of a probe as the probe is moved across an anterior surface of the patella; and
storing position information regarding the plurality of locations to form the anterior geometry of the patella;
determining a position of a posterior apex of the patella in relation to one or more features of the anterior geometry of the patella;
receiving location information related to the patella as a knee joint is moved through a range of motion; and
providing one or more recommendations to improve a patello-femoral response.
