Design outcomes

Primary

Measure	Time frame
The primary outcome in this study is long-term (10-year) stability of the Delta-TT cup combined with the H-MAX S stem and compared between a ceramic and polyethylene liner, measured in 3D translations and rotations of the Delta TT cup by means of RSA X-rays.	—

Secondary

Measure	Time frame
Secondary endpoints at 10-years postoperatively are: - Long-term stability of the H-MAX S stem, expressed in 3D translations and rotations (Method: RSA X-rays). - Implant survival of the Delta TT cup and H-MAX S stem (Method: Revision yes / no; reason for revision). - Radiographic signs of osteolysis around the cup and the stem (Method: Radiolucent lines at X-ray).	—
