ABSTRACT:
A replacement prosthesis for replacing an earlier implanted prosthesis comprises a femoral implant and a tibial implant cooperatively configured to enable first and second degrees of articulation. The femoral implant comprises a bicondylian part comprising a pair of condyles disposed so as to form an intercondylian notch and a posteriorly extending hemispherical cavity of the pair of condyles. The tibial implant comprises a tibial base, a catch mounted to the tibial base, and at least one disc removably mounted to the tibial base. The condyles are rotatably slidable on the disc to provide the first articulation. The catch member comprises an end portion which is provided with a spherical head accommodated within the central cavity of the condyles so as to provide the second articulation. The spherical head and the disc are selected from a set of heads and discs having appropriate heights and thicknesses such that a proper ligamentary tension can be obtained.
