Abstract
A total knee prosthesis comprises an upper and a lower support member provided with externally threaded, tapered shanks to which they are detachably secured, these shanks being respectively screwable into the medullary canals of a femur and a tibia of a patient to be fitted with the prosthesis. The upper support member has spherically convex rear condylar extensions coming to rest on respective pads of the lower support member which are of different height determining the physiological valgus of the patient's leg. The condylar extensions are interconnected by an axle pin received in a bifurcate projection of the lower support member; a forward extension of the upper support member forms a concave shield engageble with the natural kneecap or with a prosthetic patellar disk of the patient.
