Patient-specific arthroplasty system

Abstract

A patient-specific arthroplasty system comprising a database comprising preoperative data, ligament balancing tool data, and postoperative data associated with a plurality of patients, a preoperative evaluation module that receives preoperative data for a given patient, an analysis engine that analyzes the database, receives the preoperative data, and generates a surgical recommendation based on the preoperative data of the given patient and the analysis of the database, and a pin positioning block module that receives the surgical recommendation and determines a pin positioning block based on the surgical recommendation.

What is claimed is: 
     
         1 . A patient-specific arthroplasty system comprising:
 a database comprising preoperative data, ligament balancing tool data, and postoperative data associated with a plurality of patients;   a preoperative evaluation module that receives preoperative data for a given patient;   an analysis engine that analyzes the database, receives the preoperative data, and generates a surgical recommendation based on the preoperative data of the given patient and the analysis of the database; and   a pin positioning block module that receives the surgical recommendation and determines a pin positioning block based on the surgical recommendation.   
     
     
         2 . The system of  claim 1  wherein the preoperative data includes scans, testing, physiological analysis, and surveys. 
     
     
         3 . The system of  claim 1  wherein the preoperative data includes anatomical situations, kinematic situations, requests, and demands. 
     
     
         4 . The system of  claim 1  wherein the preoperative data includes long leg X-rays of anterior-posterior views, side views, and a patella sunrise view. 
     
     
         5 . The system of  claim 1  wherein the preoperative data includes a computed tomography scan for bony landmarks and three-dimensional impression. 
     
     
         6 . The system of  claim 1  wherein the preoperative data includes magnetic resonance imaging to obtain cartilage thickness and cartilage wear. 
     
     
         7 . The system of  claim 1  wherein the preoperative data includes electromyography testing of muscles. 
     
     
         8 . The system of  claim 1  wherein the preoperative data includes gait analysis. 
     
     
         9 . The system of  claim 1  wherein the analysis engine further generates an avatar from the preoperative data, the avatar including three-dimensional movement of a knee and adjacent joints. 
     
     
         10 . The system of  claim 1  wherein the analysis engine further stores the preoperative data to the database. 
     
     
         11 . The system of  claim 1  wherein the ligament balancing tool data includes tension data at various knee angles. 
     
     
         12 . The system of  claim 1  wherein the analysis engine further determines success and failure of prior surgical recommendations based on the postoperative data. 
     
     
         13 . The system of  claim 1  wherein the analysis engine further modifies the surgical recommendation based on the analysis of the database. 
     
     
         14 . The system of  claim 1  wherein the surgical recommendation includes parameters for the pin positioning block. 
     
     
         15 . The system of  claim 1  wherein the analysis engine further determines optimal configurations of an implant for the given patient based on a comparison to the plurality patients according to sex, age, weight, height, and physical factors. 
     
     
         16 . The system of  claim 1  wherein the pin positioning block module further produces the produce pin positioning block using a three-dimensional printer.
