Implant device and method for manufacture

Abstract

A knee implant includes a femoral component having first and second femoral component surfaces. The first femoral component surface is for securing to a surgically prepared compartment of a distal end of a femur. The second femoral component surface is configured to replicate the femoral condyle. The knee implant further includes a tibial component having first and second tibial component surfaces. The first tibial component surface is for contacting a proximal surface of the tibia that is substantially uncut subchondral bone. At least a portion of the first tibial component surface is a mirror image of the proximal tibial surface. The second tibial component surface articulates with the second femoral component surface.

What is claimed is: 
     
         1 . A method of manufacturing a shoulder implant for a patient, the method comprising:
 a. deriving the three-dimensional shape of a shoulder joint of the patient from image data of the shoulder joint, wherein the image data includes data about a shape, geometry and/or surface of the shoulder joint;   b. providing a blank with at least one dimension larger than a corresponding dimension of the shoulder joint; and   c. altering the blank to obtain a desired shoulder implant, wherein the desired shoulder implant replicates the shoulder joint of the patient in at least one dimension.
