Background and purpose: An uncemented ceramic-on-ceramic (CoC) monoblock cup is an acetabular component designed for younger and more active patients. We compared migration, revision rates, and clinical results of this uncemented CoC monoblock acetabular component with a commonly used uncemented ceramic-on-polyethylene (CoPE) modular cup.
