    摘要： Disclosed herein is a method of defining a mating surface in a first side of an arthroplasty jig. The mating surface is configured to matingly receive and contact a corresponding patient surface including at least one of a bone surface and a cartilage surface. The first side is oriented towards the patient surface when the mating surface matingly receives and contacts the patient surface. The method may include: a) identifying a contour line associated with the patient surface as represented in a medical image; b) evaluating via an algorithm the adequacy of the contour line for defining a portion of the mating surface associated with the contour line; c) modifying the contour line if the contour line is deemed inadequate; and d) employing the modified contour line to define the portion of the mating surface associated with the contour line.

    摘要： Disclosed herein is a surgical guide tool for use in total hip replacement surgery. The surgical guide tool may include a customized mating region and a resection guide. The customized mating region and the resection guide are referenced to each other such that, when the customized mating region matingly engages a surface area of a proximal femur, the resection guide will be aligned to guide a resectioning of the proximal femur along a preoperatively planned resection plane.

    摘要： 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 femoral and tibial unicompartmental arthroplasty jigs each include a first side, a second side and a mating surface. Each second side is generally opposite its respective first side. For the femoral jig, the mating surface is in the first side of the femoral jig and 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 first side of the femoral jig is configured to be oriented towards the femoral arthroplasty target region surface when the mating surface of the femoral jig matingly receives and contacts the planar area. For the tibial jig, the mating surface of the tibial jig is in the first side and 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. The first side of the tibial jig is configured to be oriented towards the tibial arthroplasty target region surface when the mating surface of the tibial jig matingly receives and contacts the planar area.
