VERILAST technology is the first device to combine an OXINIUM Oxidized Zirconium femoral component with a highly crosslinked ultra-high molecular weight polyethylene (UHM-WPE) tibial insert to form an advanced TKA bearing.

• The first knee lab tested to demonstrate wear performance sufficient for 30 years of use under typical conditions
• Offers the younger, more active patients a TKA solution designed to address their increased expectations for wear performance. 
• An often used solution in total knee replacement for patients with metal sensitivity. 

When used with LEGION Total Knee System , it demonstrated an impressive 81% reduction in wear in simulated lab testing compared to conventional materials. Plus, wear simulation indicates that the LEGION Cruciate Retaining Knee System with VERILAST Technology may last up to 30 years of wear - that's twice the current industry standard of 15 years.
