Robotic Knee Replacement

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
