Study Arms (1)

E1-Hip Bearing

E1-Hip Bearing, Evaluate E1 Wear, Clinical Performance of E1 Liner in THA in Korean Patient Population

Device: E1-Hip Bearing

Interventions

Vitamin E doping of highly cross-linked polyethylene is a proposed method for insuring long-term oxidative stability of highly cross-linked ultra-high molecular weight polyethylene for use in total joint arthroplasty. In vitro research and development studies have shown that this material has improved wear performance, retention of mechanical properties, and a high resistance to oxidation due to the anti-oxidative properties of Vitamin E.
