Total Knee Arthroplasty

NAVIO robotics assisted total knee banner


Using NAVIO in total knee arthroplasty

Total knee arthroplasty failures are mostly attributable to instability and malalignment1, with stability and proprioception shown to affect patient satisfaction- particularly for high-demand patients.2,3

NAVIO has demonstrated more accurate bone resection and alignment, through intraoperative planning, surface mapping and full range-of-motion data collection, for reduced wear and higher implant survivorship.*4-12

Watch how NAVIO works in total knee arthroplasty:

See below for guidance on:

  • Image-free registration
  • Customizable planning
  • Bone preparation
  • Postoperative assessment

Image-free registration

  • a 3D model of patient anatomy is created through direct mapping of articular bone surface
  • Full range-of-motion data collection, including soft-tissue laxity
  • No CT, MRI or preoperative imaging required


Customizable, surgeon-controlled planning

  • Intraoperative patient-specific planning for implant placement and soft-tissue balancing
  • Solid surface and cross sectional joint representation, with 3D views of transverse, saggital and coronal planes
  • Confirmation of cut guide size and placement on the bone surface

Robotics-assisted bone preparation

  • Multiple robotics-assisted bone removal options with fine-tuning adjustments.
  • Virtual tool for varus/valgus, flexion and rotation confirmation both before and after resection.
  • Handheld surgical resection tool delivers the latest cutting technology
  • Robotically-controlled precision milling for greater control and accuracy during resection


Postoperative assessment

  • Gap balancing comparisons throughout range-of-motion
  • Confirmation of final long leg alignment
