🚨 New Study Alert – Now on Arthrometer.com

A new study by Huang TC, Wang CH, Hsu KL, Kuan FC, Su WR, and Hong CK, published in the Orthopaedic Journal of Sports Medicine, confirms what many clinicians suspected:

👉 ACL-deficient knees with lateral meniscal tears show significantly greater anterior laxity
👉 MRI tibial slope? Not predictive.
👉 GNRB® robotic arthrometer? Clear, objective, and reliable.

This research reinforces the importance of robotic arthrometry in surgical planning and post-op monitoring—especially when static imaging like MRI doesn’t reveal the full extent of instability.

And for cases where rotational laxity matters just as much as translation…
🔄 Meet Dyneelax®—the first device to analyze both in one test.

📍 Live from Pune, India

An incredible experience this week working with the respected Dr Sachin Tapasvi and his talented team!

As the first surgeon in India to integrate the Dyneelax knee robotic arthrometer, Dr. Sachin Tapasvi is pioneering a new gold standard in knee ligament assessment — combining clinical examination, static MRI, and now dynamic analysis (translation + rotation).

🎥 To document this innovative workflow, Dr. Tapasvi invited a media team to record the process as we tested patients — these cases will be presented at the Pune Knee Course, which he is organizing from April 24–26, 2025.

A special mention to Dr.Apoorva Gawade PT, from Dr. Tapasvi’s team, who I had the pleasure of training during this visit. She performed the tests with precision and skill, demonstrating the capabilities of Dyneelax in a clinical setting.

🧠 I’ll be back in Pune for the course, joined by:
Mr. Stéphane NOUVEAU, CEO of Genourob
The great team at Everest Medical Technologies Pvt Ltd, including Ganesh Devrajan and Venuprasath TiruNarayanan

Proud to be the one who came to India to share this technology and personally train the Tapasvi team. The journey of improving orthopedic knee ligament treatlment continues!

📢 New Study Validates Vancomycin Soaking in ACL Reconstruction!

A newly published study in Acta Orthopaedica Belgica confirms that vancomycin soaking in ACL surgery does not weaken graft strength or compromise knee stability.

🔬 Key Findings:

✅ No Mechanical Weakness – GNRB® testing at 6 months showed that vancomycin-soaked ACL grafts maintained stability, comparable to healthy knees.
✅ Infection Prevention – Vancomycin soaking is an effective method to reduce post-operative infections without affecting graft integrity.
✅ Objective Validation – GNRB® robotic arthrometry provided quantifiable knee laxity data, ensuring accurate post-op assessments.

This research reinforces vancomycin soaking as a reliable infection control method that surgeons can confidently use without concerns about graft deterioration.

📢 Exciting New Research Alert! 📢

We are thrilled to announce a groundbreaking scientific review on the role of lateral extra-articular tenodesis (LET) in controlling sagittal knee laxity during anterior cruciate ligament reconstruction (ACLR) with short hamstring tendon grafts.

🔍 Study Overview:

Conducted by the esteemed team of Florie Frigout, Thomas Pouderoux, Caroline Vincelot-Chainard, and Henri Robert, this study explores whether LET enhances sagittal stability in ACLR procedures. With the exceptional precision of the GNRB/Dyneelax robotic arthrometer, this research offers invaluable insights for orthopedic surgeons and researchers.

📊 Key Findings:

LET does not significantly improve sagittal knee laxity post-ACLR.

The primary function of the ACL remains the control of sagittal knee laxity, with LET mainly aiding in reducing rotational instability.

💡 Why This Matters:

This review provides critical information that can help refine ACL reconstruction techniques, ultimately improving patient outcomes. The advanced technology of the GNRB/Dyneelax robotic arthrometer ensures the highest accuracy in knee laxity measurement, underscoring its importance in orthopedic research.
