Patent 5871018 Issued on February 16, 1999. Estimated Expiration Date: June 6, 2017. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.
A method for planning surgery on a body portion is provided in the steps of gathering image data, storing the image data, reading the image data into a computer, generating a three-dimensional computer model of the body portion from the image data, identifying anatomical features relevant to the surgery, and defining at least one desired correction to anatomical structures to be accomplished by the surgery. Also, a method for performing surgery on a body portion is provided in the steps of loading surgical plan data into a computer, registering a three-dimensional computer model of the body portion stored in the surgical plan data to the body portion, providing at least one surgical tool, positioning the surgical tool relative to the body portion and performing the surgery. Further, a jig assembly is provided in the form of a femoral docking jig, a femoral contouring jig, and a tibial jig.
