Knee Ligament Injury Diagnosis

Dynamic Testing.
Knee Care Reimagined.

Genourob’s knee laxity arthrometers offer unparalleled precision in ligament diagnosis. These tools are not intended to replace MRI but to complement it, applying precise translation and rotation tests to provide a detailed assessment of knee ligament integrity. This meticulous approach ensures a comprehensive understanding of each knee, offering a foundation for the most effective treatment strategies, combining the strengths of dynamic (Arthrometers) and static diagnostics (MRI).

Accurate Detection of Complete/Partial ACL Injuries

Precise Objective AM/PL Bundle Evaluation

Assessment of AM-PL & AL-PM Corners

It was confirmed with arthroscopic validation that Dyneelax/GNRB's technology surpasses MRI in detecting partial ACL ruptures.

Discover Proven Outcomes

Case Studies

“GNRB sensitivity and specificity were equivalent to those of MRI for healthy ACL and complete ACL tear detection. However, MRI had some difficulty in detecting partial ACL tears compared with the GNRB which showed better sensitivity.”

Rehabilitation Enhanced by Robotic Arthrometry

Next-Gen Rehabilitation.
Powered by Robotics.

Our robotic knee laxity arthrometers transform post-ACLR rehabilitation, enabling the delivery of personalized rehab programs. Conducting precise tests as soon as 1 month post-surgery at very small loads of force (100N max) assesses knee function early, allowing the medical corps to prescribe the right exercises at the right time. This tailored approach ensures optimized recovery outcomes and accelerates the return to activity. By combining dynamic assessments with patient-specific needs, our arthrometers set a new standard in effective, customized rehabilitation.
