DePuy Products, Barnes & Thornburg, August 7, 2012: US08236061 (54 worldwide citation)

An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.
