ROSA® Knee was designed by surgeons for surgeons as an accurate and efficient surgical assistant that also produces data. We keep you in the driver’s seat by letting you maintain your current approach, philosophy and technique, including Personalized Alignment™, so you can focus on achieving the optimal outcome for your patients.
Features and Benefits
- Multiple proven implants including: Persona® The Personalized Knee®, Vanguard® and NexGen® 1-7
- Tools for soft tissue balancing and femoral rotation
- Real-time range of motion assessment
- Perform 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 instrumentation 8
- Provides high levels of precision in regard to targeted angles and resection thickness 9
- Less outliers and 100% of cases within 3° of the targeted neutral alignment 8
- Validates all resection mean differences between target resection and measured resection were below 0.7 and had standard deviations below 1.1 mm 9
- Fewer outliers for all bone resection angles 8
- 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 modeling imaging based on X-Atlas® technology
- Imageless case option
- Reduced instrumentation through pre-operative planning
- A cornerstone of ZBEdge™, our suite of integrated digital and robotic technologies built to unlock data-powered insights across the continuum of care
- ZBEdge harnesses data from ROSA Robotics to create new value and capabilities, through an unrivaled user experience, with the goal of improving patient outcomes through informed decision-making by quantifying subjective elements of orthopedic care
- Capture more objective patient-specific data to aggregate, analyze and quantify results
