Implant Material

Better materials mean better implants

To meet the needs of today’s active patients, knee implants have to be stronger and more flexible than ever before. Advanced
materials can help create better performing, longer lasting implants.

The metal parts of the knee implant are traditionally made of a cobalt chrome-based alloy and the plastic parts are made of a high-density polyethylene. Every time metal rubs against plastic, the friction creates microscopic particles which result in wear on the implant.

However, in just the last few years, a technologically advanced bearing material called OXINIUM* Oxidized Zirconium was introduced to reduce the
wear rate over cobalt chrome metal knee implants.

OXINIUM implants may offer better results for today’s physically active patient

The OXINIUM material has proven to be a superior metal for use in the production of knee implants because of its hardness, smoothness and resistance to scratching.

OXINIUM implants have demonstrated low wear rates in laboratory testing and have shown an ability to tolerate increased activity, potentially
lasting longer than cobalt chrome knee implants.

Only an orthopaedic surgeon can provide advice on which knee implant system is right for you. Ultimately, restoring the highest level of movement
and function for your lifestyle is your surgeon’s goal. Talk to your orthopaedic surgeon to determine if OXINIUM material is an implant option
for you.
