What is OXINIUM Oxidized Zirconium?

Oxinium Knee

If it is determined that an implant made with VERILAST technology is right for you, the femoral - or thighbone portion - of your implant will be made from OXINIUM Oxidized Zirconium - a patented and award winning ceramicised metal alloy that Smith & Nephew spent more than a decade developing.

During manufacture, OXINIUM implants undergo a process that transforms the implant's surface into a hard, ceramicised metal - while still retaining all of the durability of the underlying metal. In addition to being more durable than a true ceramic, this metal implant's ceramicised surface is more than twice as hard and therefore twice as resistant to the kind of scratching that can cause a cobalt chrome implant to wear out before its time.1

VERILAST Knee Technology is exclusive to Smith & Nephew. Not every surgeon has been trained to use VERILAST Knee Implants. To find a VERILAST Knee surgeon near you, use our Find a Physician locator.

Important Safety Notes

Individual results of joint replacement vary. Implants are intended to relieve knee pain and improve function, but may not produce the same feel or function as your original knee. There are potential risks with knee replacement surgery such as loosening, wear and infection that may result in the need for additional surgery. Patients should not perform high impact activities such as running and jumping unless their surgeon tells them that the bone has healed and these activities are acceptable. Early device failure, breakage or loosening may occur if a surgeon's limitations on activity level are not followed.
