1. A method for performing a hip arthroplasty procedure comprising:
receiving a plurality of images of a patient's musculoskeletal anatomy including an image of a patient's hip in a standing position and an image of the patient's hip in a sitting position;
identifying anatomical angles within the plurality of images to define a preoperative hip geometry;
selecting one or more postoperative patient activities from a plurality of model activities to consider in optimizing prosthetic hip implant performance from a set of available postoperative patient activities;
accessing a statistical patient model that predicts prosthetic hip implant performance, based on the preoperative hip geometry and prosthetic hip implant implantation parameters, for a motion profile that is representative of each of the plurality of model activities;
calculating, from the statistical patient model, a set of proposed hip implant implantation parameters that provide a predicted prosthetic hip implant performance that meets predetermined performance criteria for the selected one or more postoperative patient activities and the preoperative hip geometry;
performing the hip arthroplasty procedure using a computer-assisted surgical system in accordance with a surgical plan to implant a prosthetic device with the set of proposed hip implant implantation parameters; and
providing a user interface to allow a user to select the one or more postoperative patient activities and to graphically display an expected post-operative performance of the prosthetic device for the selected one or more postoperative patient activities in one or more polar graphs.
