Abstract
A knee joint implant that prevents hyperextension includes a femoral component having an anterior surface with reference to the lowermost point of a convex condyle, the anterior surface being configured to have different curvature radii in respective sections thereof, and a bearing component having an anterior surface with reference to the lowermost point of a concave articular surface, the anterior surface being configured to have different curvature radii in respective sections, so that when an extended knee is about to be hyperextended, the convex condyle of the femoral component slides toward the anterior side and is brought into contact with a plurality of points of the concave articular surface of the bearing component, thereby producing resistance so as to suppress hyperextension exceeding a design range due to behavioral habits, a decrease in muscle mass, and the like of the patient.
