    摘要: A complete knee joint prosthesis having prosthetic condyles as a part of the femoral element, wherein the prosthetic condyles have a curvature in the shape of a circular arc in their rear part, and the femoral element has, between these prosthetic condyles, a convex cylindrical wall with an axis that coincides with the axis of the circle in which the rear parts of the prosthetic condyles lie. Glenoid cavities of an intermediate plate have corresponding rear parts in the shape of a circular arc and a corresponding concave bearing surface in the shape of a circular arc for pivotably receiving the prosthetic condyles. The tibial element has a cylindrical pin and the intermediate plate comprises a cavity which receives this pin to provide the possibility of multidirectional movement of the prosthetic knee joint.

    摘要: The present invention concerns to a total knee prosthesis including a femoral implant having an anterior wall that forms the upper portion of a prosthetic trochlea and two curved branches extending from the lower edge of said anterior wall, delimiting the lower portion of the prosthetic trochlea between them and forming condylar surfaces between them. The trochlea has a middle furrow bordered by two rounded convex surfaces. The trochlea has in its upper portion a flexion of approximately 50°. The trochlea has a depth smaller than the height of the longitudinal middle rib comprised by the patella and has a width larger than that of that same rib, such that the patella comes into contact with the femoral implant essentially by that rib and said concave side faces are situated at a distance from said rounded convex surfaces. In the lower portion, the trochlea has a depth greater than the height of said rib and has a width substantially equal to that of said same rib, such that the patella comes into contact with the femoral implant essentially by said concave side faces, and said rib is at a distance from the bottom of the trochlea.

    摘要: A prosthesis whose condyles (3) have a spiral form, viewed in the saggital plane and the femoral element (1) has a medial lobe (6) with a curved surface. The medial plateau (2) has glenoid cavities (2b) for the condyles (3) and a medial prominence (5) which forms a posterior support surface (5a) against which the lobe (6) is supported in the course of movement of the joint. The glenoid cavities (2b) on the medial plateau (2) and the condyles (3) are congruent in extension and in the first part of the flexion movement of the joint. The posterior sections of the condyles (3) and the medial lobe (6) inscribe circles with the same centres and the medial lobe (6) contacts against the posterior support surface (5a) at the end of the first part of movement and then rests against the posterior support surface (5a) to perform a “roll-back”.
