About this trial
This study is designed as a prospective, multi-centre, non-randomized, non-controlled study. This study does not limit the procedures involved in the treatment of the subject as long as the protocol specified products are utilized.
The primary objective is to establish the mean superior cup migration of the Emphasys Shell and the mean inferior stem migration of the Emphasys Stem using model-based RSA over the first two years post-implantation. Additionally, the data from this study will be compared to historical Pinnacle Acetabular Shell data obtained in study DSJ\_2018\_02.
