摘要： A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.

摘要： Embodiments of the present invention provide a trial coupler system for use in preparing a patient for an implant. Certain embodiments provide a system including a coupling device (20) and a trial component interface (40) that allows a trial stem (100) to be offset in relation to the respective trial components at an orientation that matches the geometry of the patient. Once the precise positioning is obtained, the trial coupler device (10) can be locked while on the patient's bone so the assembly can be removed without disturbing the desired orientation.

摘要： Methods, systems, and devices for replacement of a joint with a prosthetic system that replicates the natural kinematics of the joint is disclosed. A prosthetic system according to one embodiment includes a tibial component having a tibial plateau and a tibial stem portion, the tibial plateau having a top side and a bottom side, a tibial insert, with a bearing surface, adapted to be positioned on the top side of the tibial plateau, a femoral component having a base portion and a central housing, the femoral component having an axis of extension-flexion rotation, the base portion having a pair of condyles, a mechanical linkage component linking the tibial component with the femoral component and with the tibial insert in between the tibial component and the femoral component, so that there is a center of contact between the condyles and the bearing surface, the mechanical linkage component adapted to allow the center of contact to move posteriorly during flexion, provide for the movement of the axis of extension-flexion rotation in the superior-inferior direction, and allow rotation of the tibial component, the bearing surface, and the femoral component about a superior-inferior axis in order to provide and control the natural kinematics of the knee joint.
