Abstract: Implementations described and claimed herein provide an arthroplasty system and methods for positioning an acetabular cup implant. In one implementation, the system includes a shape-match hip guide having a patient specific mating region that is a negative of the surface contour of the inside surface of the patient's acetabular cup, and a directional rod that extends generally along the axis of the patient's femoral head and femoral neck. They system can additionally include an outrigger or silo device to aid in the alignment of surgical tools for preparing and implanting of the prosthetic acetabular cup in the patient's acetabular cup. Related methods are also disclosed herein for generating a shape-match guide and implanting an acetabular cup with the guide.

Abstract: Implementations described and claimed herein provide an arthroplasty system for making resections in a patient knee. In one implementation, the system includes a femoral cutting guide having a patient specific mating region, and a distal planar surface distally spaced from a distal resection surface based on thicknesses of femoral and tibial implants. The distal planar surface may be used to check ligament balance. The system further includes a tibial cutting guide having a patient specific mating region and a an anchor pin hole intersecting with a proximal resection slot near a medial or lateral edge of the proximal resection slot. The anchor pin hole being configured to receive an anchor pin that may serve as a sawing stop during a proximal resection.

Abstract: A method of planning an arthroplasty procedure on a femur and tibia of a patient. The method includes receiving a first two-dimensional image of the femur and the tibia, and identifying, in the first two-dimensional image, a proximal femur feature, a distal tibia feature, and a bone contour. The method further includes running a transformation process to align a bone model representative of the femur and the tibia into a coordinate system with the first two-dimensional image, the bone model having a bone model contour that is aligned with the bone contour of the femur and the tibia in the first two-dimensional image. And the method further includes applying an implant model to the bone model in order to determine coordinate locations for the arthroplasty resection.
