Active Articulation™ Dual Mobility Hip System

Dislocation is second to infection as the main early complication following THA.1 Dual mobility constructs have demonstrated long-term clinical success in Europe reducing risk of dislocation1-6,12 The Active Articulation™ E1® Hip System defines the next generation of dual mobility constructs as it is specifically indicated for patients at risk for dislocation8 and the only dual mobility system to utilize Antioxidant Infused Technology.

  • Dislocation Resistance 
  • Ultra-Low Wear - 95% less wear than traditional THA, even when cup is at 60º inclination7
  • Large Range of Motion - Provides up to 165 degrees7
  • Oxidative Stability - E1® Antioxidant Infused Technology prevents oxidative degradation of polyethylene.9
  • Clinically Proven Cup10 - The fully-hemispheric M2a-Magnum™ cup contains clinically proven PPS® coating11 and fins to provide fixation and stability
