CUSTOMIZED PROCESS FOR FACILITATING SUCCESSFUL TOTAL KNEE ARTHROPLASTY WITH OUTCOMES ANALYSIS
First Claim
1. A method for producing a custom resection jig for a current patient scheduled to receive total knee arthroplasty comprising the steps of:
- maintaining a computer searchable database of total knee arthroplasty data including a computer system of (1) prior patient bone morphologies, (2) anatomical bone axis alignment data, and (3) data defining a custom resection jig design with a generally transverse resection window operable to guide a surgeon'"'"'s generally transverse bone cut for each prior patient that has received a total knee arthroplasty procedure and a post-surgery medically recognized scoring register equal to or better than a predetermined value for a total knee arthroplasty procedure;
using bone imaging data defining a current patient'"'"'s anatomical leg axis data that is scheduled to receive total knee arthroplasty and matching with a computer current patient anatomical axis data with anatomical leg data from prior patient data within said computer searchable database of patients having post-surgery medically recognized scoring registers equal to or better than a predetermined value; and
creating a custom resection jig for the current patient with a generally transverse resection window operable to guide a physician'"'"'s resection saw making a generally transverse bone cut using as a guide the patient'"'"'s total leg anatomical leg data along with custom resection jig data, including generally transverse window geometry of the custom resection jigs, from prior resection jig designs for patients within the computer searchable database of post-surgery patient total knee arthroplasty scores having similar anatomical axis leg data.

Abstract
A method for producing a custom resection jig for a current patient scheduled to receive total knee arthroplasty using outcomes analysis comprising the steps of maintaining a database on a computer system of (1) prior patient bone morphology, (2) along with anatomical and mechanical bone alignment data and (3) data defining a custom resection jig design with a generally transverse resection window operable to guide a surgeon'"'"'s transverse bone cut for prior patients that have received total knee arthroplasty and a post-surgery medically recognized scoring register greater or equal to a predetermined highly successful score value for a total knee arthroplasty procedure using prior success data to guide production of a current patient custom jig resection windows.

26. An apparatus comprising:
one or more processors including; a database configured to correlate physical parameters associated with a total knee arthroplasty of a patient, configurations associated with a prosthesis, and operative success, an input for inputting parameters associated with a current patient; and an output for outputting a recommendation of configurations associated with a prosthesis based on at least operative success.
