Smith+Nephew’s LEGION Hinged Knee System with OXINIUM technology

Smith+Nephew’s LEGION Hinged Knee (HK) System is now available in the United States with proprietary OXINIUM (oxidized zirconium) implant technology that delivers the durability of metals, the wear resistance of ceramics, and corrosion resistance better than both.

Part of the LEGION Total Knee (TK) System, the LEGION HK system is designed to provide a natural range of motion with medial pivot, lateral roll back, and screw home. Since 2011, the LEGION HK System has enabled surgeons to transition intraoperatively from a constrained revision knee implant to a CoCr-hinged assembly.

The OXINIUM Technology has demonstrated lower inflammatory response, superior wear resistance and reduced surface damage, and fewer signs of corrosion damage compared to cobalt chrome, ultimately helping to mitigate common risk factors associated with revision procedures. LEGION revision with proprietary OXINIUM Technology has established itself as the best performing bearing with the lowest risk of re-revision compared to the class average.

Dr. Kevin Hardt, MD, at Northwestern Memorial Hospital System shares, “The LEGION HK System with OXINIUM Technology allows me to achieve a stable reconstruction in the coronal and sagittal planes despite my patient's multiple previous surgeries and ligamentous, capsular deficiency. The innovative, posteriorly located, rotational axis with the LEGION HK System provides an extension moment to augment quad function. In addition, the instrumentation is straightforward and compliments my normal revision workflow.”

“Our proprietary OXINIUM Technology is ideal for revisions. 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,” says Craig Gaffin, president of Global Orthopaedics at Smith+Nephew. “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.”
