摘要： The invention relates to a knee joint prosthesis system adapted to replace the articulating knee portion of a femur and a tibia. The knee joint prosthesis system includes a first femoral component and a second femoral component. The first femoral component includes a first femoral engagement region and a first condylar portion having a first femoral bearing surface. The first femoral engagement region is operable to engage a resecting engagement surface of the femur and the first condylar portion includes a first posterior region having a first thickness. The second femoral component includes a second femoral engagement region and a second condylar portion having a second femoral bearing surface. The second femoral engagement region is operable to engage the resected engagement surface of the femur and the second condylar portion includes a second posterior region having a second thickness. The second thickness is larger than the first thickness and the first femoral engagement region is substantially the same as the second femoral engagement region, whereby a surgeon may select either the first femoral component or the second femoral component for attachment to the femur.

摘要： A mono-condylar knee joint prosthesis that includes a femur part having a convex running surface. The knee joint prosthesis further includes a tibia part having a sliding surface which faces the femur part and an intermediate part which is introduced between the femur part and the tibia part during implantation. The intermediate part has two bearing surfaces, namely a first, concave bearing surface for cooperating with the convex running surface of the femur part as well as a second bearing surface for cooperating with the sliding surface of the tibia part. A boundary surface is provided at the tibia part which bounds the sliding surface of the tibia part and projects pointing in the direction towards the femur part in order to be able to cooperate with a side surface of the intermediate part. The boundary surface which is provided at the tibia part is formed to be curved in the shape of an arch, and the intermediate part has a side surface which is curved corresponding to the boundary surface which is provided at the tibia part and which is curved in the shape of an arch.

摘要： The invention relates to a (knee) joint for positioning two pivoting parts in such a way that they can pivot within a limited range. According to the invention, a combined turning and sliding movement is produced by means of curved guides (6, 6′, 7, 7′). A cam body (8) connected to one pivoting part, e.g. the lower leg, has two cams (10, 11; 13, 14), preferably on each side. Said cams interact with the curved guides (6, 6′, 7, 7′). The curved guides (6, 6′, 7, 7′) are located in half-shells (3, 4) which are connected to the second pivoting part, e.g. the upper leg. Parts of the inventive knee joint which are subject to wear are relatively easy to replace and movement sequences can also be modified when replacements are made.

摘要： A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available.

摘要： A complete prosthetic of the knee includes a femoral part (6) and a meniscus (3), with said femoral part (6) comprising at least one condyle (3) and a trochlea part, wherein said one or a plurality of condyles each have an external surface, the shape of which complements the respective upper surface of said meniscus (3) in order to obtain a congruence of said surfaces on at least part of the normal flexing range. At least one cavity is implemented in said trochlea such that the femoral part is blocked in its flexion by rotation in the case of negative angles beyond an inferior negative angle limit when the anterior upper edge of the meniscus comes to rest against said cavity.

摘要： A knee prosthesis and method for use are provided, in which the knee prosthesis provides anterior and posterior stability and controlled femoral roll-back, while also providing rotational kinematics. The femoral component has a pair of convexly shaped condyles which are spaced apart to form an intercondylar notch. Anterior and posterior cams are provided within the notch. The tibial component comprises a platform upon which a tibial bearing is mounted to provide for rotational movement about the tibial axis. The tibial bearing is provided with surfaces to engage the condyles and has an upwardly extending spine which is positioned to engage the anterior and posterior femoral cams. The posterior surface of the upwardly extending spine is arranged coincident with the tibial axis. At full extension, the spine engages the anterior femoral cam to provide a 3° hyperextension stop. Between full extension and approximately 50° of flexion, the spine is free to translate between the anterior and posterior femoral cams. From 50° to 120° of flexion, the spine engages the posterior femoral cam, which provides femoral roll-back and posterior stability.

摘要： An orthopaedic device for implanting on a bone includes a first component having a socket forming a first member of a morse taper lock. A second component has an end forming a second member of a morse taper lock received in the socket. A protuberance is provided on one of the first and second members. Impacting the second component inserted in the socket seats the second component in the socket, and creates a localized deformation of the interference fit between the first and second components and establishes a barrier to the passage of debris.
