Abstract

A semi-condylar artificial knee joint includes a femoral prosthesis and a tibial prosthesis, and the cross-section of the tibial prosthesis is of a kidney-like type. The tibial prosthesis is disposed at one side of the tibial plateau intercondylar eminence and is located below the femoral prosthesis. The artificial knee joint further includes a locating pin for fixing the tibial prosthesis. The bottom surface of the tibial prosthesis is provided with a prosthetic notch, and below the tibial prosthesis is provided with a tibial notch. The prosthetic notch corresponds to the tibial notch, and together forming a limiting hole for accommodating the locating pin. The cooperation between the locating pin and the limiting hole can ensure relative position stability and balance between the tibial prosthesis and the tibial plateau intercondylar eminence.
