Learn About the 30-Year Knee


Fletcher Allen’s orthopedic surgeons offer the latest technology for active knee patients: the Smith & Nephew LEGION Cruciate Retaining Knee implant with FDA-cleared VERILAST Knee Technology. This implant is an innovative solution with the potential to double the life of traditional knee implants to 30 years, under normal conditions.

VERILAST Technology: Benefits

Unlike knee implants made from cobalt chrome metal and a high-density plastic, FDA-cleared VERILAST technology combines two revolutionary materials:

  • Low-friction metal alloy OXINIUM, which is 4,900 times more abrasion resistant than cobalt chrome
  • A highly cross-linked polyethylene plastic insert

By combining these two low-friction materials, the new knee implant device can significantly reduce the kind of wear that can cause an implant to wear out before its time.

30-Year Knee: Surgery at Fletcher Allen

Fletcher Allen orthopedic surgeons are the only providers in Burlington, Vermont offering Smith & Nephew’s LEGION Cruciate Retaining Knee implant with VERILAST Knee Technology.

What makes this new knee implant superior to traditional knee implants?

  • Long-lasting. FDA-cleared VERILAST is the only knee technology laboratory tested for 30 simulated years of wear performance. This is a vast improvement over the current estimated implant lifespan of 10 to 15 years.
  • Lighter. Materials are 20 percent lighter and dramatically smoother than conventional cobalt chrome implants.
  • Hypoallergenic. The implant contains no nickel or chromium, materials that may cause problems for patients who have metal sensitivity.

Total Knee Replacement: Advanced Technology at Fletcher Allen

Our orthopedic surgeons combine VERILAST Technology with Smith & Nephew’s VISIONAIRE custom-fit surgical instrumentation system for knee replacement surgery.

We have been using VISIONAIRE technology since 2009; benefits include:

  • Reduced anesthesia time
  • Lower risk of infection
  • Reduced risk of implant misalignment
  • Reduced soft tissue and muscle damage
  • Less pain during recovery

Together, the VERILAST and VISIONAIRE technologies offer patients a longer-lasting, more natural feeling knee joint with a shorter recovery period than traditional knee joint replacement options.
