Patients with developmental dysplasia of the hip (DDH) undergo curved periacetabular osteotomy (CPO) to prevent progressive osteoarthritis. The acetabulum's morphology varies in each DDH type. Therefore, developing a three-dimensional preoperative plan is important CPO. However, optimal rotation angle osteotomized bone remains unclear. This study aimed examine contact pressure (CP) acetabular cartilage type using finite element analysis and surgical simulation.
