The present disclosure provides a femoral component having an anterior flange and a condyle opposite the anterior flange. The condyle can be augmented by a femoral posterior augment. The femoral posterior augment is securable to the condyle by a fastener which is actuated to a securement position by a rotatable driver which does not contact the anterior flange through rotation of the driver sufficient to actuate the fastener to secure the femoral augment to the condyle.
