Designed by surgeons for surgeons, the ROSA® Knee System provides objective soft tissue feedback and accurate bone resections, which aim to restore a patient’s natural knee. ROSA Knee collects intra-operative metrics to inform your decision-making and provide data-driven insights, so you can focus on achieving the optimal outcome for each patient.
ROSA® Knee System: Robotic Knee Replacement
Predictive Planning, Precise Performance

Features and Benefits

Surgeon-Centered
You’re in the Driver’s Seat
Maintain your current
approach and surgical technique, including Personalized Alignment™.
Quantify Previously Subjective Information
Objectively
measure soft tissue and predictively plan a balanced knee replacement
before performing any resections.
Easy to Integrate with Minimal Learning Curve1,2
Offering an Enhanced TKA Surgical Experience
TKA with
robotic surgical assistance results in less physician stress and
strain than conventional methods.3
Implants Designed to Improve Outcomes
Technologies are only as good as the implants they are used
with. ROSA Knee supports our leading knee brand: Persona®
The Personalized Knee®4-9, including the Persona® OsseoTi® Keel Tibia.

Accurate
Delivers Highly Accurate Resections and Limb Alignment10
A recent in vivo study reported that:
- The average difference between the planned and executed resections for all measurements was <1° and <1 mm with standard deviations <1 for each.
- The average difference between planned and executed hip-knee-ankle (HKA) angle was 1.2° ± 1.1°.
Improved Precision and Accuracy Versus Conventional
Instrumentation11
In a prior cadaveric study
comparing conventional versus robotic instrumentation, 25% of knees
were outside of ± 3° of the planned alignment when conventional
instrumentation was used. However, all robotic cases using ROSA Knee
were within ± 3° of planned alignment.

Efficient
Flexible Imaging Options
Offers both image-based and
imageless options for greater flexibility. While some surgeons opt for
the operational efficiency of working imageless, others appreciate the
benefits of utilizing image-based cases with X-Atlas® 2D to
3D Technology.

Data-Driven
Making the best decision when it matters requires data-driven
intelligence.
A cornerstone of ZBEdge™
Dynamic Intelligence™, with the power to elevate
and unlock the full potential of Zimmer Biomet’s cutting-edge suite of
integrated digital technologies, robotics and implant solutions.
