All patients received a posterior stabilised total knee replacement with a fixed insert (PFC Sigma; DePuy Orthopaedics, Inc; Warsaw, IN, USA). The tibial guide was aligned with the sulcus between the tibial spines and the middle of the posterior cruciate ligament at the knee and with the tibialis anterior tendon at the ankle.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The average post\u2010operative coronal mechanical alignment was 1\u00b0 varus (range 4.5\u00b0 varus\u20131.5\u00b0 valgus; SD \u00b11.51). The average post\u2010operative rotational deviation from the transepicondylar axes (TEA) was 0.78\u00b0 of internal rotation (1.50\u00b0 of internal rotation \u2212 3.5\u00b0 of external rotation) for the tibial component. The whole\u2010extremity mechanical axis deviation was outside the tolerance range of 3\u00b0 in 4 patients (8.9 %). Deviation of the tibial component rotational position relative to the TEA was 3\u00b0 or less in 94.5 % of the patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>When the tibial component is aligned using the axis drawn from the centre of the PCL to the sulcus between the tibial spines on the proximal tibia and to the tibialis anterior tendon at the ankle, good alignment will be achieved in both the coronal and axial
