Name Time Method Defference of stem antetorsion (by neck axis)between 3D pre-operative planning and post-operative implantation.
- Secondary Outcome Measures
Name Time Method Differences between 3D pre-operative planning and post-operative implantation in the following items. -Stem angle differences in antetorsion (by stem axis), varus / valgus, and flextion / extension. -Depth from center of stem. -Stem spatial position differences in x (coronal)-axis, y (sagittal)-axis, and z ( axial)-axis. -Cup angle differences in radiographic inclination (RI) and radiographic anteversion (RA). -Cup spatial position differences in x (coronal)-axis, y (sagittal)-axis, and z(axial)-axis. Leg length discrepancy. Adverse event.
