Do you have the next BIG IDEA in MedTech?
Making the best decision when it matters requires data-driven intelligence.
The ROSA Robotic Knee Replacement System supports surgeons in performing Total Knee Arthroplasty with features to assist with bone resections and assessment of soft tissue state to facilitate implant positioning intra-operatively.
The system is a cornerstone of ZBEdge™, our suite of integrated digital and robotic technologies built to unlock data-powered insights across the continuum of care.
Tools for soft tissue balancing and femoral rotation
Real-time range of motion assessment
Performs multiple techniques including Personalized Alignment™, Gap Balancing, Measured Resection and Hybrid
Adapts to surgeon workflow with intuitive user interface
Offers surgeons precision and accuracy through cut flow and validation feature, designed to ensure proper alignment in real time. Enables more accurate and more reproducible resections than conventional instrumentation8
Provides high levels of precision in regard to targeted angles and resection thickness9
Less outliers and 100% of cases within 3° of the targeted neutral alignment8
Validates all resection, mean differences between target resection and measured resection were below 0.7 and had standard deviations below 1.1mm9
Fewer outliers for all bone resection angles8
With real-time soft tissue balancing, surgeons can determine resections based on each patient’s soft-tissue and bony anatomy
2D x-ray to 3D bone modelling imaging based on X-Atlas® technology
Imageless case option
Reduced instrumentation through pre-operative planning
ZBEdge harnesses data from ROSA Robotics to create new value and capabilities, through an unrivalled user experience, with the goal of improving patient outcomes through informed decision-making by quantifying subjective elements of orthopaedic care
Captures more objective patient-specific data to aggregate, analyse and quantify results
