Arthroplasty system and related methods
First Claim
1. A method of manufacturing an arthroplasty jig, the method comprising utilizing a computer processing device to perform the operations of:
- a.) generate a bone model, wherein the bone model includes a three dimensional computer model of at least a portion of a joint surface of a bone of a patient joint to undergo an arthroplasty procedure;
b.) generate an implant model, wherein the implant model includes a three dimensional computer model of at least a portion of a joint surface of an arthroplasty implant to be used in the arthroplasty procedure;
c.) assess a characteristic associated with the patient joint, the characteristic being at least one of a shape of a condyle surface of the patient joint or a joint gap spacing of the patient joint;
d.) generate a modified joint surface of the implant model by modifying at least a portion of a joint surface of the implant model according to the characteristic;
e.) shape match the modified joint surface of the implant model and a corresponding joint surface of the bone model; and
f.) employ data obtained from operation e.) in the manufacture the arthroplasty jig.

30. A method of manufacturing an arthroplasty jig, the method comprising utilizing a computer processing device to perform the operations of:
-
a.) generate a bone model, wherein the bone model includes a three dimensional computer model of at least a portion of a knee joint surface of a patient femur to undergo an arthroplasty procedure; b.) identify at least one of a most distal point and a most posterior point of a condyle articular surface of the bone model; c.) generate an implant model, wherein the implant model includes a three dimensional computer model of at least a portion of a joint surface of a femoral arthroplasty knee implant to be used in the arthroplasty procedure; d.) identify at least one of a most distal point and a most posterior point of a condyle articular surface of the implant model; e.) move at least one of the bone model and the implant model so the at least one of the most distal point and the most posterior point of the condyle articular surface of the bone model generally positionally correspond with the at least one of the most distal point and the most posterior point of the condyle articular surface of the implant model; and f.) employ data obtained from operation e.) in the manufacture the arthroplasty jig. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
