First Claim
1. A method suitable for analyzing surgical techniques, said method comprising:
- a. generating three-dimensional computer models of orthopedic devices, said devices selected from the group of orthopedic instruments and implants, wherein data corresponding to said models is stored in a memory system of a computer;
b. generating three-dimensional models of a targeted surgical site on a body portion based upon tomographic data stored in the memory system for the surgical site;
c. inputting into said memory select target values corresponding to one or more measurable technical parameters associated with said surgical procedure, said parameters selected from the group consisting of three-dimensional positioning and dimensions of bones, three-dimensional positioning and dimensions of soft tissue structures, three-dimensional positioning and dimensions of said orthopedic devices for surgery, and predicted values corresponding to range and forces associated with physiologic joint motion and joint laxity;
d. attaching one or more tracking devices to said body near said target surgical site, said tracking devices operatively in communication with said computer system;
e. performing a surgical procedure on said target surgical site;
f. communicating tracking data generated during said surgical procedure to said computer system;
g. calculating actual values based upon said tracking data, said actual values corresponding to said technical parameters set for the surgical procedure; and
h. comparing said target values and said actual values of said technical parameters after performing said surgical procedure.

Abstract
A method is disclosed for analyzing surgical techniques using a computer system for gathering and analyzing surgical data acquired during a surgical procedure on a body portion and comparing that data to pre-selected target values for the particular surgical procedure. The inventive method allows the surgeon, for example, to measure the technical success of a surgical procedure in terms of quantifiable geometric, spatial, kinematic or kinetic parameters. The method comprises calculation of these parameters from data collected during a surgical procedure and then comparing these results with values of the same parameters derived from target values defined by the surgeon, surgical convention, or computer simulation of the same procedure prior to the operation itself.
