A bicruciate-retaining femoral implant component for a knee implant system comprises a first surface comprising two distinct single radii of curvature in a sagittal plane matching a predetermined cylindrical axis of the knee along with a medial surface comprising a first asymmetric geometry substantially congruent with respect to a first native knee geometry and a lateral surface comprising a second asymmetric geometry substantially congruent with respect to the first native knee geometry. In an embodiment, bone resectioning proximate a medial condyle and a posterior condyle for total knee arthroplasty (TKA) comprises using the femoral component after obtaining a pre-operative image of a predetermined region on a knee to be replaced and morphing data collected from the image into a three dimensional model of the knee sufficient to allow modeling software to define a patient specific cylindrical axis. The femoral component is designed as a dual single-radius femoral implant component to conform to a geometry defined about that cylindrical axis.
