Comparison of postoperative result to the preoperative plan of the femur with Materialise 3-matic software. Each picture shows two porcine femoral bone models. The preoperative model is grey while the achieved result is green. Both models were fitted proximally (automatic registration, a). Subsequently, the measurements of varus/valgus (b), procurvatum/recurvatum (c) as well as rotation (d) were performed distally. The blue lines indicate a tangent to each of the bone at defined points. For varus/valgus and rotation a tangent to the most distal point of the medial and lateral distal femoral condyle was drawn. For procurvatum/recurvatum, the tangent was fitted to the anterior femoral cortex on a lateral view. The angle between these lines represents the respective deviation from the plan
