Abstract
The femoral component of a knee prosthetic includes a trochlean part ( ) and at least one, but preferably two condyles ( ) wherein a trochlean trajectory is defined within the external surface of the component by the trochlea. A set of internal flat sides ( and ) are implemented to make contact with corresponding re-cut sides of the extremity of the femur and define an internal open cage within the internal surface of said component and further define edges ( and ) between themselves. The perpendicular projection ( ) of said trochlean trajectory in the medial lateral perspective of said femoral component has a tilt angle (alpha) with a value different from zero relative to the line ( ) perpendicular to the perpendicular projection of said edges in said medial lateral perspective.
