Disclosed herein are unicompartmental femoral and tibial arthroplasty jigs for respectively assisting in the performance of unicompartmental femoral and tibial arthroplasty procedures on femoral and tibial arthroplasty target regions. The jigs each include a mating surface. The mating surface of the femoral jig is configured to matingly receive and contact a generally planar area of an anterior side of a femoral shaft generally proximal of the patellar facet border and generally distal an articularis genu. The mating surface of the tibial jig is configured to matingly receive and contact a generally planar area of an anterior side of a tibial shaft distal of the tibial plateau edge and generally proximal of the tibial tuberosity.
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's knee joint, the tibia including an area of an anterior side of a tibial shaft distal of a tibial plateau edge and proximal of a tibial tuberosity, the tibia further including a medial tibia condyle, the tibial tuberosity including a medial edge, a lateral edge, a proximal boundary and a beginning of a distal half to distal third of the tibial tuberosity, the tibial arthroplasty procedure being associated with an implantation of a prosthetic tibial implant, the jig comprising:
