摘要：
An orthopedic knee prosthesis (10) comprising: a femoral component (12) having a condyle surface (52, 54) curved in the sagittal plane； and a tibial support (14) having a support surface (32) configured to articulate with the condyle surface of the femoral component, where the condyle surface (i) contacts the support surface (32) at a first point of contact (112) on the condyle surface at a first degree of flexion, the first degree of flexion being less than about 30 °, and (ii) contact the support surface (32) at a second contact point (114) at the condyle surface in a second degree of flexion, the second degree of flexion being in the range of 45 ° to 90 °, where (i) the condyle surface in the sagittal plane has a first radius of curvature at the first point of contact, (ii) the condyle surface in the sagittal plane has a second radius of curvature at the second point of contact, (iii) the proportion of the first radius of curvature with the second radius of curvature is in the range of 1.10 to 1 , 45, characterized in that the super Condylar fiction contacts the support surface at a third point of contact (116) of the condyle surface at a third degree of flexion that is greater than the second degree of flexion, and the condyle surface in the sagittal plane has a third radius of curvature at the third point of contact, the third radius of curvature being greater than the second radius of curvature by at least 0.5 mm.Una prótesis ortopédica de rodilla (10) que comprende: un componente femoral (12) que tiene una superficie de cóndilo (52, 54) curvada en el plano sagital； y un soporte tibial (14) que tiene una superficie de soporte (32) configurada para articularse con la superficie de cóndilo del componente femoral, donde la superficie de cóndilo (i) contacta con la superficie de soporte (32) en un primer punto de contacto (112) en la superficie de cóndilo en un primer grado de flexión, siendo el primer grado de flexión inferior a aproximadamente 30º, y (ii) contac
