    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 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 femoral component for a hip joint prosthesis comprises a proximal portion adapted to be received in the intertrochanteric region of a femur, a neck portion extending obliquely medially, anteriorly and superiorly from the proximal portion and adapted to be joined to a femoral head element, and a stem portion smoothly merging with and extending inferiorly from the proximal portion. The proximal portion has anterior and prosterior aspects that converge medially and inferiorly and intersect a rounded medial aspect oriented obliquely to the stem portion both anteriorly and medially, said aspects defining a generally wedge-shaped body adapted to engage the endosteal surfaces of the femur in the intertrochanteric region such that substantially all loads are transmitted from the component to the bone in the intertrochanteric region and load transfers through other surfaces are minimized.

    摘要： A total hip joint prosthesis has a ball, replacing the ball of the hip joint ball and socket, affixed to the femur by a stem. Stem stress is reduced by providing a rounded cross-section of the stem truncated along the lateral side in the critical section subject to greatest cyclic loading. The stem is of controlled low flexibility so that when the bone cement and stem composite structure is in place, the bone is subject to a maximum percent of normal stress from bending moments. By virtue of the truncated shape and its size relative to the bone cavity, stress in the stem is minimized when the stem alone carries the load.

    摘要： A knee joint prosthesis comprises femoral and tibial components. The femoral component includes a pair of condyles each curved generally to match the shape of an anatomical femoral condyle. The surface of each condyle is defined by (a) anterior posterior radii R.sub.CF and R.sub.CE, wherein R.sub.CF is the radius of curvature Of that portion of the condyle which is weight bearing in flexion and R.sub.CE represents that portion of the curvature of the condyle which is weight bearing in extension, and (b) a medial lateral radius R.sub.CML. The tibial component includes a pair of concavities, each of which is adapted to receive one of the condyles of the femoral component. The surfaces of the concavities are defined by an anterior posterior radius R.sub.TAP and a medial lateral radius R.sub.TML. The foregoing radii are selected to optimize the balance between range of motion and knee longevity.
