    摘要： A knee joint prosthesis includes a femoral component having a first condylar bearing surface and a second condylar bearing surface. Each of the first and second condylar bearing surfaces has a cross-section in a coronal plane that exhibits at least two different radii. The prosthesis also includes a tibial component and an insert component associated with the tibial component. The insert component has bearing surfaces that are complementary to the first and second condylar bearing surfaces, wherein a contact point is established between the bearing surfaces of the insert component and the first and second condylar bearing surface. In accordance with the present invention and as a result of the above construction, varus and valgus rotation of the femoral component relative to the insert component causes the contact point to move laterally as the knee is rotated. By shifting the contact pointy laterally/outwardly, the knee stability (i.e., stiffness) gradually increased.

    摘要： A prosthetic joint according to the present invention includes a first implant component for attachment to a first bone and a second implant component for attachment to a second bone. The first implant component has a condylar portion that includes first and second condylar bearing surfaces and similarly, the second implant component has bearing surfaces that receive and are complementary to the first and second condylar bearing surfaces. Each of the first and second condylar bearing surfaces and each of the bearing surfaces of the second implant component has a cross-section in a coronal plane that exhibits two different radii and a contact point is established between the first and second condylar bearing surfaces and the bearing surfaces of the second implant component. The bearing surfaces of the respective implant components are configured such that varus and valgus rotation of the first implant component relative to the second implant component causes the contact point to move outwardly.

    摘要： A clamp device, cutting guide, and clamp slider used together in preparation to cutting of the distal end of the femur bone during total knee replacement surgery. The clamp device includes an upper arm and a lower arm rotatably secured to one another in a scissor-like manner. A curved movable component is rotatably secured to the proximal end of the lower arm. The clamp device is positioned around a portion of the distal end of the femur bone so that the distal end of the upper arm grasps a posterior ridge of the femur bone and the movable component of the lower arm is positioned along the contour of the deepest part of the trochlear groove, thereby defining a plane through the deepest part of the trochlear groove of the femur bone. Next, a clamp slider is removably secured to a cutting guide so that channels defined in the clamp slider and cutting guide are substantially aligned with one another. The assembled clamp slider and cutting guide are then slid over the clamp and rotated until the clamp is received in the channels with the cutting guide in contact with an anterior portion of the femur bone. Then the cutting guide is positioned so that arms projecting from each side are substantially aligned with a center of the medial or lateral epicondyle of the femur bone. Lastly, the clamp slider and clamp are removed, whereby the cutting guide remains properly aligned on the femur bone in order to ensure the correct angle of the cuts in the femur bone.
