The company says its system delivers the durability of metals, wear resistance of ceramics and corrosion resistance better than both. London-based Smith+Nephew’s Oxinium (oxidized zirconium) implant technology offers lower inflammatory response, superior wear resistance and reduced surface damage with fewer signs of corrosion damage compared to cobalt-chrome, according to a news release.

Oxinium implant technology helps to mitigate the common risk factors associated with revision procedures. Legion revision with Oxinium delivers high-performing bearing with low risks of re-revision compared to the class average, Smith+Nephew says.

Legion HK, part of the Legion total knee (TK) system, offers a natural range of motion. Smith+Nephew designed it to provide medial pivot, lateral roll back and screw home motions. It enables surgeons to transition intraoperatively from a constrained revision knee implant to a cobalt-chrome-hinged assembly.

“Our proprietary Oxinium technology is ideal for revisions,” said Craig Gaffin, president of Global Orthopaedics at Smith+Nephew.
“Building on the proven performance of our Legion HK system, our latest innovation allows Smith+Nephew to raise the bar in knee surgery, delivering the most advanced material technology for patients requiring a complex knee revision.

It demonstrates our commitment of life unlimited for patients requiring complex knee procedures by providing solutions that address the risk factors commonly associated with this type of surgery.”
