A bone prosthesis for the leg and thigh comprises a distal femoral component that includes a body portion adapted to replace a resected portion of the distal femur and a condylar portion having a spherical surface along its inferior and posterior aspects and an axle hole extending through it in the latero-medial direction at the geometric center of the sperical surface and a proximal tibial component that includes a metal head portion having a cavity opening superiorly and defined by spaced-apart lateral and medial flange portions, each of which has an axle hole. A plastic tibial plateau insert is received in the cavity of the tibial head portion and has a spherical seat matching, receiving and pivotably supporting the femoral condylar spherical surface. A plastic bushing is received in the axle hole of each tibial flange portion, and a metal axle is received in the femoral and tibial axle holes. Clearances between the bushings and the portions of the axle received in the bushings provide latero-medial flexural and axial rotational laxities in the prosthetic joint throughout the range of flexural motion. A shaft component is used interchangeably to replace portions of the tibial and femoral shafts. A diaphysis component is provided or total femoral replacement. A proximal femoral component, used in conjunction with the shaft component or diaphysis component, replaces the femoral part of the hip joint. Identical Morse-type taper couplings are used to connect shaft components to joint components.
