摘要：
A prosthetic knee joint comprising: a femoral component (110) including a body (112) with a front side, a back side, a pair of condylar portions (114, 116) laterally spaced, and an intercondylar portion ( 130) joining the condylar portions and including a intercondylar recess the front side having a surface (170) of femoral cam and a tibial component (200) including a platform (210) with an upper surface (214) including concavities second (224, 226) laterally spaced being adapted each of them to receive a condylar portion (114, 116 ) of the femoral component (110) and a tibial post (240) for reception in the intercondylar recess of the femoral component, wherein the tibial post (240) a tibial surface (250) of anterior cam includes a section that is defined by the least a second radius (R2) of substantially convex curvature and a fourth radius (R4) of concave curvature which is perpendicular to the second convex radius of curvature, to form a shaped saddle is configured to mate with the femoral surface (170 ) cam, wherein the surface (170) of femoral cam is complementary to the tibial surface (250) and cam is defined by a first radius (R1) of curvature at least substantially concave yu n third radius (R3) perpendicular to the first radius (R1) of curvature concave to form a cam surface shaped saddle convex curvature.Una prótesis de articulación de rodilla, que comprende: un componente femoral (110) que incluye un cuerpo (112) con un lado anterior, un lado posterior, una pareja de porciones condilares (114, 116) separadas lateralmente, y una porción intercondilar (130) que une las porciones condilares y que incluye un rebaje intercondilar teniendo el lado anterior una superficie (170) de leva femoral y un componente tibial (200) que incluye una plataforma (210) con una superficie superior (214) que incluye unas segundas concavidades (224, 226) separadas lateralmente, estando adaptada cada una de las mismas para recibir una porción condilar (114, 116) del componente fe
