About NAVIO◊

NAVIO Handheld Robotics

The freedom of robotics in your hands

The NAVIO Surgical System is designed to offer accuracy1-9, value5 and freedom at the cutting edge of robotics-assisted surgery; helping surgeons improve outcomes6 and patient satisfaction6-8 in total and partial knee arthroplasty.*

Now featuring version 7.0 software for a more streamlined surgical workflow, shorter learning curve and real-time access to intraoperative case information**.

Grow your practice, with the latest step in robotics technology

Currently the only handheld robotics system for knee arthroplasty

 Freedom: Handheld technology and a compact footprint for full portability across your OR and surgical centers. Find out why surgeons choose NAVIO 

Accuracy: Clinically proven to deliver the accuracy patients deserve1-4 for implant placement9, alignment9 and bone resection*1-9, and to help reduce procedural variation10.

 Value and efficiency: Image-free preoperative mapping, eliminating the cost and implications of CT scans11, with potential to expand your robotics portfolio with additional handpieces. Shown to have a lower cost of ownership compared to other solutions.5

 Patient satisfaction: With 25% of knee arthroplasty patients showing dissatisfaction12-15, NAVIO Handheld Robotics improves alignment, stability and proprioception16,17, which may help implant survivorship18 factors commonly associated with patient satisfaction19,20.

Give patients the confidence to get the surgery they need.

What’s new?

The next step - NAVIO 7.0 operating system upgrade

The NAVIO 7.0 software upgrade provides the next evolutionary step in robotic-assisted in joint surgery, delivering a surgical workflow designed to improve efficiency and usability, and further decrease the learning curve**:

Fewer registration steps

  • 72% reduction in required data point collection, with automatic landmark capture**
  • 40% reduction in workflow stages, with improved usability**21 and faster, image-free mapping 
  • 2.5x larger data point collection area, with faster surface model generation**22
  • Single stage, patient-specific planning
