Claims

[Scope of utility model registration request]

In an artificial knee joint consisting of an L-shaped curved spherical femoral cup fixed to the femoral side and a tibial plate having a spherical bearing surface for receiving the femoral cup and fixed to the tibia side, the femoral cup is fixed to the tibia side. A cross-shaped protrusion is provided on the inner surface of the femur to fix the femoral cup by being driven into the lower surface of the femur, and an umbrella is provided on the lower surface of the tibial plate to fix the tibial plate by being driven into the upper surface of the tibia. An artificial knee joint characterized by having a shaped protrusion.
