Embodiment 1
[0038] An artificial total knee prosthesis, the artificial total knee prosthesis is a cruciate ligament-retaining prosthesis, that is, a CR prosthesis, such as figure 1 and figure 2 As shown, it includes femoral condyle 1, liner 2 and tibial tray 3 connected in sequence, and the upper surface of the liner 2 forms a sliding fit with the femoral condyle 1, while the lower surface of the liner 2 cooperates with the tibial tray 3, the The contact surface between the liner 2 and the tibial tray 3 is a smooth surface.
[0039] The above-mentioned femoral condyle 1, liner 2 and tibial tray 3 are all made of polyetheretherketone or its derivatives. The derivatives of polyetheretherketone can be carbon fiber reinforced polyetheretherketone, glass fiber reinforced polyetheretherketone, etc. .
[0040] The value range of the modulus of elasticity of the above-mentioned femoral condyle 1 is 10GPa~25GPa; image 3 and Figure 4 As shown, the lower surface and the upper surface of the f...
Embodiment 2
[0046] An artificial total knee prosthesis, which is a post-stabilized prosthesis, i.e. a PS-type prosthesis, adopts a fixed platform design, including a femoral condyle 1, a liner 2 and a tibial support 3 connected in sequence, And if Figure 7 and Figure 8 As shown, the upper surface of the liner 2 forms a sliding fit with the femoral condyle, while the lower surface of the liner cooperates with the tibial tray, and the contact surface between the liner 2 and the tibial tray 3 is a smooth surface.
[0047] The above-mentioned femoral condyle 1, liner 2 and tibial tray 3 are all made of polyetheretherketone or its derivatives (such as carbon fiber reinforced polyetheretherketone, glass fiber reinforced polyetheretherketone, etc.).
[0048] The value range of the modulus of elasticity of the above-mentioned femoral condyle 1 is 10GPa~25GPa; Figure 9 and Figure 10 As shown, the lower surface and the upper surface of the femoral condyle 1 are respectively provided with a p...
