"Smith & Nephew is the only company in the world to commercialize an advanced bearing surface for the femoral component of a knee replacement. OXINIUM™ oxidized zirconium is a proprietary material which has been used in more than 200,000 knee procedures and is proven to reduce wear. It is also the only hypoallergenic metal bearing surface since it contains no detectable amounts of nickel, the element commonly associated with metal allergies.
"VERILAST technology is the unique combination of our exclusive OXINIUM material and the most advanced XLPE on the market. Together, they yield virtually indiscernible wear. After performing wear simulator testing of the knee replacements over three continuous years, we have confirmed that this Smith & Nephew knee replacement made with VERILAST technology, under normal circumstances, is expected to last for 30 years."
Typically, if a knee replacement fails due to wear, the patient will undergo a "revision" surgery in which the original components will be replaced with more invasive, more expensive ones. While there may be some decrease in implant performance, the primary costs of revision surgery are in its risk of infection and bone loss for the patient and the procedure's cost for the healthcare system.
"If we're successful in our drive to make knee replacements that last a lifetime, that could mean significant cost savings to the healthcare system," said DeVivo. "And patients may avoid the pain and the downtime associated with revision surgery."
