Measurement of torsional parameters of the lower extremity on 3-dimensional computed tomography. a. The tibia external rotation was defined as the angle between the line connecting the posterior tibial condyles and the line connecting the midpoints of the medial and lateral malleoli. b. The femoral anteversion angle was defined as the angle between femoral neck axis (red line) and posterior condylar of distal femoral axis (yellow line)
