Abstract

Disclosed are systems, devices and methods for optimizing the manufacture and/or production of patient-specific orthopedic implants. The methods include obtaining image data of a patient, selecting a blank implant to be optimized for the patient, and modifying the blank implant utilizing techniques disclosed herein to alter specific features of the implant to conform to the patient's anatomy.

First claim

What is claimed is:

1. A method of making a knee implant system for repairing a knee joint of a patient, comprising:
a. determining a three-dimensional shape of at least a portion of an articular surface of the knee joint of the patient from electronic image data of the knee joint of the patient;
b. altering a first blank implant to form a femoral implant, wherein at least a portion of an articulating surface of the femoral implant conforms to the three-dimensional shape, wherein the femoral implant further includes one or more femoral standard features;
c. altering a second blank implant to form a tibial implant, wherein at least a portion of an articulating surface of the tibial implant complements a corresponding portion of the articulating surface of the femoral implant, wherein the tibial implant includes one or more tibial standard features.

2. The method of claim 1 , wherein the corresponding portion of the articulating surface of the femoral implant conforms to the three-dimensional shape.

3. The method of claim 1 , wherein the corresponding portion of the articulating surface of the femoral implant includes the one or more femoral standard features.

4. The method of claim 1 , wherein the one or more femoral standard features includes a standard intercondylar distance.

5. The method of claim 4 , wherein the one or more tibial standard features includes a feature configured based on the standard intercondylar distance.

6. The method of claim 1 , wherein the one or more femoral standard features includes a standard anchoring mechanism for the femoral implant.

7. The method of claim 1 , wherein altering a first or second blank implant includes subtracting and/or adding material to one or more portions of the first or second blank implant.
