Measurement accuracy was defined as the difference between the intraoperative measurements of stem anteversion obtained using the conventional or improved version of instrument and the postoperative measurements of stem anteversion obtained using postoperative CT. We compare the measurement accuracy in same patient using the conventional or improved version of instrument. Implantation accuracy was defined as the difference between the target stem anteversion using improved version of instrument and the postoperative measurements of stem anteversion obtained using postoperative CT. Intervention period is intraoperative period. We observe the intervention group for 6 months. Control group is the patient that reported previously using conventional instrument. We compare the measurement accuracy in patient using the conventional instrument and improved version of instrument.
