The Anatomic Dual Mobility (ADM™, Stryker Orthopaedics, Mahwah, NJ, USA) design provided significantly greater posterior horizontal dislocation distances compared with the Modular Dual Mobility (MDM™, Stryker Orthopaedics), subhemispheric dual-mobility, and standard fixed-bearing designs in cup ranges between 48 and 60 mm. PHDD = posterior horizontal dislocation distance.
