17. A computer aided orthopedic surgery system for performing an arthroplasty procedure of a joint comprising:
an orthopedic distraction device that includes:
an upper paddle for engaging a first bone of a joint,
a coupler for attachment to a second bone of the joint,
a displacement mechanism operable to displace the upper paddle relative to the coupler, and
a controller operatively in communication with the displacement mechanism, and configured to apply a displacement force to displace the upper paddle from the coupler;
a three-dimensional position tracking system for tracking a position of the first bone and the second bone of the joint; and
a computer operatively in communication with the three-dimensional position tracking system having:
a first 3D computer implant model associated with the first bone and a second 3D computer implant model associated with the second bone,
a display that includes an interface for displaying a planned position and size of the first 3D computer implant model associated with the first bone and a planned position of the second 3D computer implant model associated with the second bone,
a memory having computer program instructions, and
a processor programmed to execute the computer program instructions to:
determine a relative position of the first and second bones of the joint based upon the applied displacement force,
determine a predicted gap based on the relative position of the first and second bones and dynamically update the predicted gap based on changes to the position and/or size of the first or second 3D compute implant models, and
display, on the display, the predicted gap.
