What this Trial Is About
The purpose of this clinical study is to investigate whether patients who receive modified anteversion angle (( α-15°)±10°) of the acetabular cup have a lower risk of dislocation within one year after surgery, compared to patients who receive conventional anteversion angle ( α±10°) of the acetabular cup. The hypothesis is that patients with placement of the modified (( α-15°)±10°) anteversion angle of the acetabular component will have decreased risk of dislocation 1 year after surgery compared to patients with conventional anteversion angle ( α±10°) placement. PS: α refers to the preoperative anteversion angle of the affected hip. α equals to the anteversion angle of the contralateral limb if it cannot be accurately measured on the affected limb. A standard error within 10° is accepted
