摘要：
A prosthesis (10) of orthopedic knee posterior stabilized, comprising: a component (12) including femoral (i) a pair of condyles (52,54) spaced apart defining a escotaduraescotadura (56) intercondylar therebetween, having at least one pair of condyles separate from a surface (100) condyles, curved in the sagittal plane, and (ii) a posterior cam (80) on the intercondylar escotaduraescotadura and a tibial support (14) including (i) a platform (30) having a surface (32) support configured to articulate with the condyle surface of the femoral component, and (ii) a protrusion (60) extending upwardly from the platform, in which the condyle surface of the femoral component (i) contacts the bearing surface at a first contact point on the condyle surface at a first degree of flexion, (ii) contacts the support surface at a second contact point on the condyle surface at a second degree of flexion being greater the second degree of flexion to the first degree of flexion and being in the range of between about 0 degrees and about 50 degrees, and (iii) contacts the bearing surface at a third contact point on the condyle surface at a third degree of flexion, the third degree of flexion greater than the second degree of flexion and less than 90 g Rados approximately and in which the condyle surface with a first radius of curvature is curved in the sagittal plane at the first contact point, a second radius of curvature is curved in the sagittal plane at the second contact point, and a third radius of curvature is curved in the sagittal plane at the third contact point, characterized in that the initial contact between the posterior cam of the femoral component and the protrusion of the tibial bearing takes place in a fourth degree of flexion, the fourth degree of flexion not being greater than about 10 degrees more than the third degree of flexion.Una prótesis (10) de rodilla ortopédica posterior estabilizada, que comprende: un componente (12) femoral que incluye (i) un par de cóndi
