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
