Distal femoral measurements. a Identification of the trans-epicondylar axis (TEA). b Measuring the femoral mediolateral (fML) length. c Line 1 is drawn tangential to the lowest point of the lateral femoral condyle and parallel to the TEA in a corresponding axial cut. d Line 2 is drawn tangential to the highest point of the lateral distal femoral condyle (LDFC) and parallel to the TEA, measuring the femoral anteroposterior (fAP) length as the distance between Line 1 and Line 2
