Generation and applications of CT images of the ideal standing position for total knee arthroplasty surgery

Abstract

CT images with body weight loading are desired for preoperative planning on TKA surgery. In our proposed method, we perform stress analysis by the finite element method (FEM) for bone mesh structure by generating CT images, and we estimate an ideal standing position of the loaded state (referred to as deformed CT images of the ideal standing position). We also compare the deformed CT image with CR images, and evaluate the effectiveness in several ways.
