  • Patent number: 9675464
    Abstract: A tibial tray system includes a tibial tray configured for attachment to a surgically-prepared surface of the proximal end of the tibia. The tibial tray includes a track disposed in a generally A-P direction. The tibial tray system also includes a spline configured to engage the track and to be positionable in at least one location along the track. The spline includes a bearing surface that is configured to contact a femoral component of the knee prosthesis to guide movement of the femoral component during extension and flexion of the knee.

  • Patent number: 9308674
    Abstract: Implant body has a groove into which an outer ring is fitted. The body and ring are distinct solid parts both during and after assembly. A “flat” wall may be provided for the groove. The outer ring is annularly continuous and may be under tension, with the body under correspondent compression from the ring. An arthroplasty device can be provided.

  • Patent number: 9259508
    Abstract: Ceramic bodies can be made by providing an initial green body of ceramic; and machining the initial green body to provide a machined green ceramic body. Embedding the initial green body in an embedding mass can be avoided. The initial green body can be bisqued, infiltrated an adjuvant such as machining wax, removing the infiltrated body, and machining it. Highly detailed ceramic products can be generated. The machined green ceramic body may be fired and/or further processed to provide a more finished ceramic body. Examples include a femoral component for a posterior stabilized knee implant, a component body for an artificial rotation device containing knee implant prosthesis a dental implant or bridge, an ice skating blade, and so forth. Zirconia ceramics are advantageously employed, for an example, Mg-TTZ.

  • Patent number: 9162008
    Abstract: Prosthetic implant or component therefor of a magnesium oxide stabilized transformation toughened zirconia (Mg-TTZ) ceramic can be made by providing a bisqued initial green body by compressing powder through a cold isostatic press and heating to a bisque stage. Then, without embedding it in an embedding mass, the bisque is machined to have a shape of the same proportions as the shape of, but larger than, the ceramic portion of a fired prosthetic implant or component product. Firing can provide the fired Mg-TTZ ceramic body product.

  • Patent number: 9078754
    Abstract: Hard substance wear couple has materials of differing hardness forming surfaces for articulation in a joint implant prosthesis. For instance, a first articulating body can have a convex articulating surface, and a second articulating body can have a corresponding concave articulating surface that can articulate with the convex articulating surface of the first articulating body, in which the convex articulating surface of the first articulating body is harder than the corresponding concave articulating surface of the second articulating body. Ceramic materials are preferred.

  • Publication number: 20130245777
    Abstract: A knee system includes a knee prosthesis having a tibial arrangement including a tibial tray configured for attachment to a surgically-prepared surface of a proximal end of the tibia. The tibial arrangement also includes a tibial insert system including a lateral tibial insert and a medial tibial insert. One of the inserts is configured to move in a generally anterior-posterior direction relative to the tibial tray, and the other insert is configured for fixed attachment to the tibial tray. The knee prosthesis also includes a femoral component configured for attachment to a surgically-prepared surface of a distal end of a femur. The femoral component and tibial inserts each have articular surfaces configured to contact and articulate relative to each other during extension and flexion of the knee.
