Difference in Rotational Alignment of the Tibial Component, as Determined by the Range-of-Motion Technique and Akagi's Line, is Influenced by Tibial Varus Deformity: A Cross-Sectional Study

The ROM technique and Akagi's line yielded significantly different values for the rotational alignment of the tibial component. Orthopedic surgeons using Evolution (CS) should be reminded that in knees with proximal tibial varus deformity, the ROM technique will result in external rotation of the tibial component in relation to Akagi's line.
