NAVIO™ Surgical System Overview
The NAVIO™ Surgical System is a surgical planning,
navigation and intraoperative visualization system
combined with a handheld smart instrument for
bone sculpting.
The optical tracking camera communicates the
relative position of the handpiece (cutting tool), the
femur, and the tibia (via rigid tracker arrays) to the
computer cart, which runs algorithms that control
the handpiece (Figure 2).
The patient’s bone is prepared according to an
intra-operative plan that combines soft-tissue and
anatomic information to control bone removal and
prepare for rigid fixation of the NAVIO reusable cut
guides, which include the distal femur cut guide
and tibia cut guide, according to the component
placement plan.
NAVIO Total Knee surgery can be broken up into
the following stages. For clarity, this technique
guide is separated into sequential sections:
1. System and Patient Setup
2. Bone Tracking Hardware
3. Surgical Preferences
4. Registration
5. Ligament Balancing
6. Implant Planning
7. Implant Planning - Soft Tissue Balancing
8. Bone Cutting
9. Trial Reduction
10. Cementing Final Components & Closing
The implant planning and bone cutting stages are
customizable as per the workflow preferences
selected by the user, highlighted in the Surgical
Preferences section (Section 3) of this guide.
