Femoral component of a knee prosthesis, comprising at least one, preferably two, condyles, on the posterior side; a trochlea part on the anterior side, in the upper surface of which a trochlea trajectory is defined; and a set of planar inner faces, intended to come into contact with corresponding resected faces of the end of a femur, defining an open inner cage on the inner surface of the component, the set of planar faces comprising a first planar anterior end face, a second planar intermediate face and a third planar posterior end face, characterised in that between the planar anterior end face and the planar intermediate face, a dome-shaped surface is formed having its concavity facing the outer side of the component.
