Kinematic and Parameterized Modeling for Patient-Adapted Implants, Tools, and Surgical Procedures

Abstract

Patient-adapted articular repair systems, including implants, instruments, and surgical plans, and methods of making and using such systems, are disclosed herein. In particular, various embodiments include methods of selecting and/or designing patient-adapted surgical repair systems using parameterized models and/or multibody simulations.

What is claimed is: 
     
         1 . A method of producing a system for treatment of a joint of a patient, the system including an implant and a jig, the method comprising:
 receiving preoperative patient-specific image data of the joint;   performing a first segmentation of at least a portion of the patient-specific image data to create a first model of one or more surfaces of the joint;   performing a shape search of a case database of pre-existing implant designs;   selecting the original implant design from the case database of pre-existing implant designs that is a best fit with the model;   performing a second segmentation of a select local portion of the patient-specific image data to create a refined model of at least a portion of a surface of the joint;   designing a personalized jig based, at least in part, on the refined model;   manufacturing the personalized jig;   providing an implant based on the original implant design; and   packaging the personalized jig with the implant,   wherein the joint is a knee joint.   
     
     
         2 . The method of  claim 1 , wherein providing includes modifying the original implant design to improve fit with the first model. 
     
     
         3 . The method of  claim 1 , wherein providing includes modifying the original implant design based, at least in part, on the refined model. 
     
     
         4 . The method of  claim 1 , wherein the implant is based on the original implant design without modification. 
     
     
         5 . The method of  claim 1 , wherein the select local portion of the patient-specific image data is a subset of the at least a portion of the patient-specific image data upon which the first segmentation was performed. 
     
     
         6 . The method of  claim 1 , further comprising:
 receiving preoperative patient-specific ligament information;   performing a multibody simulation based, at least in part, on the selected original implant design and the patient-specific ligament information.   
     
     
         7 . The method of  claim 6 , wherein providing includes modifying the original implant design based on results from the multibody simulation. 
     
     
         8 . The method of  claim 6 , wherein the implant is based on the original implant design without modification.
