Is distal femoral torsion the same in both of a patient's legs? Morphometric CT study

Is distal femoral torsion the same in both of a patient's legs? Morphometric CT study IntroductionThe rotational position of the femoral component is a primary driver of success in total knee arthroplasty. However, distal femoral torsion (DFT) varies greatly between individuals. Measuring DFT preoperatively by CT in combination with computer-assisted surgery can significantly improve the rotational positioning of the femoral component. However, a preoperative CT scan is costly and exposes the patient to radiation. These are doubled when the patient is undergoing bilateral arthroplasty. The aim of this study was to determine the DFT in both knees of a patient undergoing bilateral arthroplasty. We hypothesized that DFT was symmetric between a patient's two knees and was independent of frontal alignment. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Orthopaedics & Traumatology: Surgery & Research Elsevier

Abstract

IntroductionThe rotational position of the femoral component is a primary driver of success in total knee arthroplasty. However, distal femoral torsion (DFT) varies greatly between individuals. Measuring DFT preoperatively by CT in combination with computer-assisted surgery can significantly improve the rotational positioning of the femoral component. However, a preoperative CT scan is costly and exposes the patient to radiation. These are doubled when the patient is undergoing bilateral arthroplasty. The aim of this study was to determine the DFT in both knees of a patient undergoing bilateral arthroplasty. We hypothesized that DFT was symmetric between a patient's two knees and was independent of frontal alignment.
