Tibial component

摘要

According to one aspect of the present invention, there is provided a tibial component (10), suitable for use in an orthopedic prosthesis, which prosthesis includes a femoral component and a spacer bearing (70), the tibial component comprising a planar tibial plate (15) having an upper bearing surface (30) and a lower attachment surface (20), and the tibial plate further having at least one spacer bearing attachment means for removably securing the spacer bearing to the tibial plate.

主权项

1. A tibial component, suitable for use in an orthopedic prosthesis, which prosthesis includes a femoral component and a spacer bearing, wherein the tibial component is shaped to be used in at least one of the medial and lateral compartments of a knee, the tibial component comprising:
a planar tibial plate having an upper bearing surface and a lower bone connecting surface, the tibial plate being adapted to interchangeably in situ receive anteriorly-loaded spacer bearings for either mobile- or fixed-bearing prosthetic assemblies; the tibial plate further having at least one anteriorly located spacer bearing attachment means for removably securing the spacer bearing to the tibial plate; and wherein the interchangeability of the spacer bearing between mobile and fixed assemblies is immediate or subsequent to a revision procedure, without disturbing bone connecting surfaces of the tibial component.
