A Legacy of Clinical Success
There are many factors that ultimately influence implant endurance. Smith & Nephew has been at the forefront of innovation in the area of endurance, as demonstrated through a legacy of success. The design of the LEGION◊ Total Knee System was inspired by the GENESIS◊ II Total Knee System, which has a longstanding record of clinical success. For many years and in more than 30 countries, the GENESIS II Total Knee System has achieved outstanding clinical outcomes. 1,2,3

Smith & Nephew has a longstanding reputation for providing surgeons with technologies designed to maximize implant wear resistance. That reputation was built through market leading innovations such as our highly polished tibial baseplates, tibial locking mechanism and the award-winning OXINIUM◊ Oxidized Zirconium. That history of innovation continues with VERILAST◊ Technology. In lab testing, Smith & Nephew demonstrated that the composition of the mating component has a significant influence in the wear resistance of the entire bearing couple (see VERILAST chart 1 below).
