The invention discloses a silicon nitride ceramic artificial knee joint, which consists of an artificial femoral condyle, an artificial tibial plateau and an artificial patella and relates to the technical field of artificial joints. The artificial femoral condyle, the artificial tibial plateau and the artificial patella are all made of silicon nitride ceramic materials, and the silicon nitride ceramic artificial knee joint has various excellent performances of a biological ceramic implant, high hardness, high bending strength, high fatigue strength, high fracture toughness, excellent friction performance, good bone length and bone growth capacity, good anti-infection capacity and good developability, and can solve the problems of abrasion and stress shielding of the artificial knee joint. |
