1. A computer-implemented method for preoperatively evaluating impingement following arthroplasty and providing a surgical plan based on computer-based modeling and simulation, the method comprising:
accessing, by a computing device a plurality of images of a site of the arthroplasty, including a computed tomography scan of a person in a supine position and at least one planar radiographic image of the person in a sitting position or a standing position;
generating, by the computing device using at least the computed tomography scan, -a virtual three-dimensional model of at least a bone of the person;
translating and/or rotating the virtual three-dimensional model of at least the bone of the person to align the virtual three-dimensional model with at least the planar radiographic image of the person;
simulating, by the computing device based on the virtual three-dimensional model, movement associated with the bone at the site of the arthroplasty;
determining, by the computing device based on the simulating, occurrence, location and type of the impingement;
identifying, by the computing device using the determined location and type of the impingement, a plurality of surgical plans for treating the impingement, wherein each of the surgical plans has a degree of treatment effectiveness and a degree of invasiveness; and
selecting, by the computing device, one of the surgical plans in accordance with the selected plan's predetermined degree of effectiveness and predetermined degree of invasiveness.
