dc.description.abstractIndividualized preoperative assessment of the patterns of the lower extremity anatomy and deformities in patients undergoing total knee arthroplasty seems essential for a successful surgery. In the present study, we investigated the relationship among the coronal alignment and the rotational profle of the lower extremities in the Caucasian population with endstage knee osteoarthritis. We conducted a prospective study of 385 knees that underwent a preoperative threedimensional computed tomographybased model. The lower extremity alignment was determined (mechanical tibiofemoral or hipkneeankle angle, supplementary angle of the femoral lateral distal angle, and proximal medial tibial angle). For each case, the femoral distal rotation (condylar twist angle), the femoral proximal version, and the tibial torsion were determined. As the coronal alignment changed from varus to valgus, the femoral external rotation increased (r= 0.217; p< 0.0005). As the coronal alignment changed from varus to valgus, the external tibial torsion increased (r= 0.248; p< 0.0005). No correlation was found between the global coronal alignment and the femoral version. The present study demonstrates a linear relationship between the coronal alignment and the rotational geometry of the distal femur. This correlation also occurs with the tibial torsion. Perhaps outcomes of total knee arthroplasty surgery might be improved by addressing these deformities as well.es
