The invention discloses an axis type knee joint prosthesis, and belongs to the technical field of artificial prostheses. The device comprises a femoral condyle prosthesis, a tibial plateau support and a three-way structure, the top end of the femoral condyle prosthesis is connected with the osteotomy section through cone fit, and a transversely-penetrating shaft hole is formed in the joint end of the femoral condyle prosthesis. A counter bore is fixed in the center of the top of the tibial plateau support; one end of the three-way structure is positioned in the fixed counter bore; the other two opposite ends of the three-way structure are positioned in the shaft hole of the femoral condyle prosthesis; a tibial plateau pad corresponding to the joint end face of the femoral condyle prosthesis is arranged at the top of the tibial plateau support; the joint end face of the femoral condyle prosthesis is located on the upper surface of the tibial plateau pad. The adaptability and the stability of the method are rem
