ROSA® Knee System

Meet Our Robotic Knee Replacement System

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.

Features and Benefits
  • Multiple proven systems including: Persona® The Personalized Knee®, Vanguard® and  NexGen®1,2,3,4,5,6,7

  • 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
