Design outcomes

Primary

Measure	Time frame
The primary target is the reduction in bone density as the difference between immediate postoperative value (5 - 10 days) and 1 year after surgery. This is to be measured by DEXA (Dual Energy X-Ray Absorptiometry).	—

Secondary

Measure	Time frame
Examination of the relationship between cup design and reduction of the periacetabular bone density after 1 year	—
