8. A method of performing an arthroplasty procedure of a joint using a computer aided orthopedic surgery system that includes an orthopedic distraction device, a three-dimensional position tracking system, and a computer operatively in communication with the orthopedic distraction device and the three-dimensional position tracking system, comprising:
attaching the orthopedic distraction device to a first bone of a joint before any bone resections of the first bone and a second bone of the joint, the orthopedic distraction device including:
an upper paddle for engaging the second bone, and
a displacement mechanism operable to displace the upper paddle relative to the first bone;
using the orthopedic distraction device, applying a displacement force to displace the upper paddle from the first bone;
using the three-dimensional position tracking system, determining a relative position of the first bone and the second bone upon application of the displacement force; and
using the computer, determining a predicted gap between the first and second bones of the joint based on the relative position of the first bone and the second bone and the displacement force.
