Ortho Guidance express knee software
Express knee surgical planning and guidance software powered by Ortho Q Guidance system
The precision and capabilities of our express knee software enables a simpler, less invasive approach to total knee replacement and has helped make us the industry technology leader in orthopaedic navigation.1
Inherent in our express knee software and proprietary active optical tracking technology are numerous features designed to help optimize your performance, workflow and time in the OR while helping simplify the complex clinical tasks and decisions you face.
Features and benefits
- Open, agnostic implant platform
- Rapid registration
- Automatic and semi-automatic processing
- Sophisticated anatomical algorithms
- Ability to run active trackers/pointers
- MIS jig for less invasive approach
- Abundant surgeon preferences and workflow options
- Post-operative analysis
- Intuitive ease of use
Less invasive:
Helps minimize risk
- MIS jig for distal femur/proximal tibia alignment/resection and femoral rotation
- Limits anchoring devices; patient trackers attach to fixation plate
- No additional skin incisions; navigation tracker pins placed on articular surface
- Eliminates need for intramedullary guide
Smart, streamlined workflow
- Only fully autonomous system in the industry
- Automatic and semi-automatic processing provides a multitude of vital anatomical metrics
- Smart instruments with industry-leading accuracy
- Cut-check verification of distal femoral/proximal tibia resections without requiring an anatomy survey
- No need for tracker pins in femur or tibia shafts
- Low latency PC displays virtual model onscreen in real time
Femoral rotation calculations
Multiple metrics to aid femoral resection
Cut alignment verification
Quick, easy digitization of knee/tibia center and other patient-specific references.
Precision per patient
- Virtual model of patient’s knee helps you tailor surgical approach
- Proven reproducibility of good alignment/positioning2
- Data and visuals to help you control all six degrees of freedom when making bone cuts
- Virtual cut planning/locations prior to actual execution
- Surgeon confirmation/safety checks built in
- With Ortho Q Guidance system, provides precise navigational guidance
Proven benefits of surgical guidance
95% accuracy reproducing mechanical axis of knee in TKA2 compared to 73% for conventional instrumentation3
Optimizes implant alignment to promote improved patient outcomes4
Can help combat anterior femoral notching which occurs in 3.5-26.9% of conventional TKAs5
