Robotic Control 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

Surgeon-Centered
Multiple proven systems including: Persona® The Personalized Knee®, Vanguard® and NexGen®

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

Accurate
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

Provides high levels of precision in regard to targeted angles and resection thickness

Less outliers and 100% of cases within 3° of the targeted neutral alignment

Validates all resection, mean differences between target resection and measured resection were below 0.7 and had standard deviations below 1.1mm

Fewer outliers for all bone resection angles

With real-time soft tissue balancing, surgeons can determine resections based on each patient’s soft-tissue and bony anatomy
