The FEA model that showed body weight was placed on the superior aspect of the sacrum and the load of the flexor muscles of the hip joint was placed on the ilium. a. Anteroposterior view of the FEA model. b. Lateral view of pelvic 20° anteversion model. The load of the flexor muscle (100 N) of the hip was calculated using the moment arm equation. c. Lateral view of pelvic 0 anteversion model. The load of the flexor muscle (500 N) of the hip was calculated using the moment arm equation. d. Lateral view of pelvic 20° retroversion model. The load of the flexor muscle (950 N) of the hip was calculated using the moment arm equation
