Ceramic Modular Dual Mobility in Primary Total Hip Arthroplasty (THA)

A randomized controlled trial comparing modular dual mobility inserts with ceramic multilayer coating versus standard polyethylene inserts for primary THA in a cementless acetabular cup

The aim of this study is to show in a randomized controlled trial that cobalt and chromium ion serum levels are comparable to the metal ion levels in patients with standard articulation with metal head. The metal on polyethylene articulation is accepted as standard articulation since many decades, and which is currently in the Czech Republic the most used combination. Most studies which focused on the topic of metal ion release from modular dual mobility systems do not present results of a control group with standard articulation hip implants.
