Overview

NAVIO Robotics-assisted total knee arthroplasty

Available for the JOURNEY II, LEGION, and GENESIS II Total Knee Systems, the NAVIO system is designed to deliver accuracy through intraoperative implant planning, handheld robotics, and NAVIO-specific cut guides during total knee arthroplasty. NAVIO intraoperative planning software uses soft-tissue and 3D surface capture to collect joint laxity, enable accurate implant positioning, and customize a solution for each patient without the need for a preoperative CT scan.

CT-free registration

  • Virtual representation of a patient’s anatomy
  • Direct mapping of articular bone surface
  • Soft-tissue laxity collection throughout the entire ROM

Surgeon-controlled planning

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

Robotics-assisted bone preparation

  • Multiple bone removal options:

- Captured saw cuts placed with robotic-assistance
- Fine-tune bone preparation with robotic-assisted bur for 0.5mm resection level   adjustments

  • Virtual resection tool to confirm varus/valgus, flexion and rotation for both pre and post bone removal



Postoperative assessment

  • Comparison of achieved gaps throughout ROM
  • Confirmation of final long leg alignment
