NUsurface® knee implant diagram

The NUsurface® Implant is a non-anchored interpositional knee implant designed for patients with persistent knee pain following medial meniscus surgery. Treatment with the NUsurface® Implant has the potential to fill the gap between minimally invasive meniscus repair and total knee replacement. The implant is made from polycarbonate-urethane (PCU) – a medical grade plastic. As a result of its unique materials and composite structure and design, it does not require fixation to bone or soft tissues. The NUsurface® Implant mimics the function of the natural meniscus and redistributes loads transmitted across the knee joint.


The NUsurface® Implant is designed to:

  • Restore deficient bio-mechanics
  • Re-establish load distribution across knee joint
  • Help protect articulating cartilage from further deterioration
  • Be semi-constrained and self-centering
  • Be performed in a minimally invasive procedure
  • Be stable without requiring fixation, drilling, sutures or significant bone resection
  • Be easily removed to allow for future treatment options
