25 patients will receive a cemented THA with a BiMobile dual mobility cup, in a standard size after optimal reaming, resulting in a cement mantle of approximately 2mm.
25 patients will receive a cemented THA with a BiMobile dual mobility cup, in one size smaller than standard after optimal reaming, resulting in a cement mantle of approximately 4mm.
