Abstract
A tibial component for a knee prosthesis comprises a tibial platform and a wedge-shaped keel which is disengageably attachable to the tibial platform. The tibial platform has a superior surface for supporting a fixed or mobile bearing component and an inferior surface which, when the tibial platform and the keel are engaged with each other, is spaced from an upper surface of the keel. A knee prosthesis having the tibial component , and a system are also provided.
Claims22
A tibial component for a knee prosthesis, the tibial component comprising a tibial platform and a wedge-shaped keel which is disengageably attachable to the tibial platform, the tibial platform having a superior surface for supporting at least one of a fixed and mobile bearing component and an inferior surface which, when the tibial platform and the keel are engaged with each other, is spaced from an upper surface of the keel.
A tibial component for a cementless knee prosthesis, the tibial component comprising a tibial platform and a wedge-shaped keel for connecting the tibial platform to a tibia, at least a portion of the tibial platform having a coating of osteoconductive material for encouraging growth and fixation of the tibia to the tibial platform.
A tibial component for a knee prosthesis, the tibial component comprising a tibial platform and a keel for connecting the tibial platform to a tibia, the keel being pyramid shaped and having a V-shaped or substantially V-shaped lateral cross-section.
A modular tibial component system for a knee prosthesis, the system comprising one or more tibial platforms and two or more wedge-shaped keels disengageably attachable to the tibial platforms, the tibial platforms and keels varying in dimensions, and each tibial platform and keel being selectable intra-operatively.
A keel for a tibial component, the keel being wedge-shaped and disengageably attachable to a tibial platform of the tibial component.
