In the past, efforts to reduce wear focused on improving implant design and polyethylene quality. Now there is OXINIUM Oxidized Zirconium, available exclusively from Smith & Nephew. Hardness, lubricity and abrasion resistance are all improved. Knee simulator wear testing of OXINIUM material showed an 85 percent decrease in polyethylene wear compared to cobalt chrome. Our products may help patients live better. OXINIUM is a material that may last longer.
Features of OXINIUM include:
- Ceramic bearing surface reduces risk of fracture
- Surface transformation, not a coating
- Suitable for metal sensitive patients
- Highly wettable, abrasion resistant and low friction ceramic surface
- Long term mechanical and chemical stability
*care needs to be exercised with all bearing surfaces intra-operatively.
