Measurement of (A) the slope of the tibia plateau and (B) the orientation of the fibular notch. The measurements were carried out using the coordinate system as shown. The lateromedial (LM), posterior-anterior (PA), anterior-posterior (AP) and inferior-superior (IS) directions are shown, with the IS direction corresponding to the anatomical axis. The transverse plane (TR), the inclination of the tibial plateau (I), the most anterior point on the border of the articular surface of the medial tibial condyle (AMC), the most posterior point on the border of the articular surface of the medial tibial condyle (PMC), the tangent plane (TA) and the coronal plane (C), all used in measuring the slope of the tibial plateau and the orientation of the fibular notch, are marked.
