A gauge assembly includes a distal femur gauge including medial and lateral condyle paddles each having a shape and size corresponding to a pre-operative planned distal resection of a patient's femur, and a tibial cutting block connected to the distal femur gauge. The condyle paddles include features, for example, pin-receiving holes, that permit intra-operative anterior-posterior and/or internal-external adjustment of the position of the distal femur gauge. The tibial cutting block includes features, for example, pin-receiving slot and holes, that permit fixing of the varus-valgus and flexion-extension degrees of freedom prior to fixing the internal-external and medial-lateral degrees of freedom.
