The hip joint secondary to osteoarthritis due to high contact pressure by osteonecrosis of femoral head needs to be considered when performing a preservation hip surgery. In this study, the hip joint contact pressure and load transfer path of femoral head by giving an intertrochanteric curved varus osteotomy with several types of lesions were investigated using a finite element method. The contact pressure decreased and the load transfer path widened after this osteotomy. The intertrochanteric curved varus osteotomy could remove the lesion out of weight-bearing area as well as an effective way to decrease the joint contact pressure.
