Partial Knee Arthroplasty

Partial Knee Arthroplasty


Using NAVIO in partial knee arthroplasty

The NAVIO◊ Surgical System has proven effective in unicompartmental knee arthroplasty, showing significant improvements to limb alignment1, component positioning1 and restitution of the joint-line height.2

Designed to help surgeons achieve more accuracy in bone resection and alignment through intraoperative planning, surface mapping and full range-of-motion data collection, for reduced wear and higher implant survivorship.*2-10

Watch how NAVIO works in unicompartmental knee arthroplasty:

See below for guidance on:

  • Image-free registration
  • Customizable planning
  • Robotically-assisted execution 

Image-free registration

  • Patient-specific anatomic and kinematic data collection
  • Provides a 3D model of patient anatomy
  • No CT, MRI or preoperative imaging

Customizable, surgeon-controlled planning

  • Size, orient and align components virtually on a 3D model
  • Confirm implant placement relative to the articulating surface
  • Adjust implant placement to balance soft-tissue throughout the full range-of-motion (UKR only)

Robotic-assisted bone preparation

  • Handheld surgical resection tool delivers the latest cutting technology 
  • Robotically-controlled precision milling for greater control and accuracy during resection
