A set of instruments and a surgical technique facilitate precise orientation of the femoral implant. Precision is aided by decoupling the determination of A/P placement, valgus angle, and external rotation into three discrete steps. In this way, a surgeon’s full concentration can be directed to each element of placement and? ne adjustments can readily be made to each. An Epicondylar Guide is con? gured to ease referencing external rotation from the epicondyles. The narrow elongated guide is easily alignable with the epi condyles when it is placed on the? at distal cut. A Posterior Reference/Rotation Guide can be attached to the Epicondy lar Guide to check the rotation relative to the intact posterior condyles to con? rm the epicondylar setting. A slot in the guide guides a saw blade to cut a corresponding slot in the distal femur. An A/P Cutting Guide has a? n that? ts in the slot cut in the distal femur. With the A/P Cutting …
