Claim:
1. A tibial arthroplasty jig for assisting in the performance of a tibial arthroplasty procedure on an arthroplasty target region of a tibia of a patient knee joint, the tibia including a tibial shaft, a tibial plateau edge, a tibial tuberosity, and the arthroplasty target region, wherein the tibial shaft near the patient knee joint includes a shaft surface on an anterior side of the tibial shaft, the shaft surface being distal of the tibial plateau edge and generally proximal of the tibial tuberosity, the arthroplasty target region including a tibial plateau including a medial articular plateau surface and a lateral articular plateau surface, the tibial arthroplasty jig comprising: a first mating surface configured to matingly contact the shaft surface when the tibial arthroplasty jig is applied to the tibia to perform the tibial arthroplasty procedure on the arthroplasty target region, wherein the first mating surface comprises a surface negative of the shaft surface and the first mating surface exists in the tibial arthroplasty jig at least as early as the tibial arthroplasty jig being completely manufactured; and a second mating surface configured to matingly contact the medial articular plateau surface when the tibial arthroplasty jig is applied to the tibia to perform the tibial arthroplasty procedure on the arthroplasty target region, wherein the second mating surface comprises a surface negative of the medial articular plateau surface, the second mating surface exists in the tibial arthroplasty jig at least as early as the tibial arthroplasty jig being completely manufactured, wherein the first and second mating surfaces are separated by a first region of non-contact between the tibial arthroplasty jig and the arthroplasty target region of the tibia when the tibial arthroplasty jig is applied to the tibia to perform the tibial arthroplasty procedure on the arthroplasty target region.
