Knee replacement solutions

The future of Total Knee Arthroplasty (TKA)

A new, all-polymer PEEK-OPTIMA™ femoral knee component for total knee replacement?

PEEK-OPTIMA polymers offer performance characteristics such as modulus and flexural strength close to that of cortical bone, contributing to bone density preservation, and radiolucent material properties that allow artifact-free imaging during and after implantation. The polymer has proven biocompatibility and biomechanical benefits in implantable spine, trauma and other devices that provide safety, longevity and reassurance to patients and surgeons, and could now hold the key to future innovations in total knee replacements*.


*The device is not approved for sale in the U.S. or internationally.

The potential for superior clinical outcomes and improved patient satisfaction from a metal-free implant, together with improved health economic outcomes makes this a significant advancement in orthopedic technology.
