Embodiment Construction
[0037] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.
[0038] See Figure 1 ~ Figure 4 As shown, in a specific embodiment of the present invention, the cementless tibial component of the trabecular bone structure of the present invention includes a tibial plateau 1, a liner 2 and a trabecular bone structure 3, and the trabecular bone structure 3 is set On the lower surface 11 of the tibial plateau 1, the tibial plateau 1 and the trabecular bone structure 3 are integrally formed, the liner 2 is welded on the upper surface 12 of the tibial plateau 1, and the tibial plateau The upper surface 12 of the platform 1 is a rough surface with a microporous structure. The microporous structure has no special requirements, tetrahedrons and hexahedrons are acceptable, and the liner raw material 4 to be processed in a molten state (mentioned in the step (2) of the preparation method below) can enter the micro...
