High-Tech, Affordable Knee Ligament Diagnostics & Treatment Arthrometers for Modern Healthcare

Time To Rethink Knee Ligament Treatment
MRI (Static Testing) is the current gold standard standard for diagnosing knee ligament injuries.
Yet, global health authorities note their frequent overuse and high cost.
Knee robotic/dynamic arthrometers offer a groundbreaking solution to this problem: Dynamic Knee Testing
These dynamic arthrometers surpass MRIs in detecting partial ACL tears, delivering greater efficiency at a lower cost.
By suggesting MRIs only when needed, they aim to lower patient costs and maintain MRI availability for more severe cases, like cancer for example.
It’s crucial to note that our approach does not seek to replace MRI but rather to complement it when a rupture is confirmed.
Pairing Dynamic Arthrometer Examinations with Static MRI Techniques significantly refines overall patient management.
Welcome and step into the future of orthopedics with robotic arthrometers DYNEELAX/GNRB, where innovation meets affordability.

Introducing Dynamic Knee Laximetry: DYNEELAX

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).

Advanced Antero-Posterior Knee Stability Testing

Diagnose Partial & Complete ruptures of the Anterior Cruciate Ligament (ACL).
Analyse the state of resistance of the ACL by applying automated anterior tibial translation (Automated Lachman Test).
Results are shown under the form of compliance curves (force/displacement curves) + Tables Chart with displacement data.

ACL Compliance Curves

Exploring Knee Rotation: Medial-Lateral Examination

Evaluate structures surrounding the ACL by applying robotic tibial medial / lateral rotations.
Results are shown under the form of curves (degree/torque curves) + Tables Chart with rotation data.

Peripheral Structures Medial/Lateral Rotation Curves

Enhance Surgical Planning with Realistic Dynamics

The dynamic test simulate every day knee stresses, providing a comprehensive framework for precise surgical planning. This, coupled with MRI static results, offers a holistic view of knee health.
Translation findings reveal the condition of the ACL, while rotation outcomes determine the need for Extra-Articular Plasty, ensuring a well-rounded approach to treatment and recovery.


Ensuring Comfort and Safety

Our tests use non-invasive technology for safe, painless knee diagnostics, ensuring a stress-free experience. Gentle yet advanced, our automated techniques accurately assess ligament conditions without discomfort, allowing for thorough examinations with minimal patient disruption.


Reproducibility: The Core of Precision Medicine

The combination of advanced sensors, defined testing parameters, and a uniform procedure delivers reproducible results that healthcare professionals can trust. This reliability enhances the precision of treatment plans, offering patients a clear path to recovery and bolstering confidence in their care.


Preventing ACL Injuries: Proactive Measures & Continuous Monitoring

Thanks to our system's high reproducibility, we maximize the effectiveness of early detection and preventive strategies, paving the way for ongoing follow-ups. This structured approach seamlessly transitions into rehabilitation, focusing on recovery and building strength.

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.
