Study highlights the superior reliability and reproducibility of knee balancing technology compared to conventional methods.
A new cadaveric study published has been published in the Journal of Experimental Orthopedics (JEO). The study highlights the superior reliability and reproducibility of knee balancing technology compared to conventional methods—a significant milestone in enhancing patient outcomes. Combined with GPS®, the Newton Knee technology offers dynamic soft tissue analytics, pre-resection operative insights and full-range personalized planning designed to simplify, evaluate and execute balanced total knee replacement surgery.

Conducted by researchers from Newco and the University of Montpellier, France, the study compared knee balancing technology to traditional manual gap measurement methods commonly used with competing systems, like robotics. Results demonstrated that Newton Knee balancing technique consistently outperformed conventional methods in reliability, regardless of surgeon experience.
“This study confirms that Newton Knee balancing system enables reliable and reproducible acquisitions of the medial and lateral space, offering significant value compared with conventional manual techniques, including with robotics,” said Gérard Giordano, Head of the Orthopedic Department at the Joseph Ducuing Hospital in Toulouse, France. “By enabling more accurate ligament balance assessments, the technology plays a crucial role in optimizing implant placement and improving functional outcomes, contributing significantly to the progress of personalized surgical planning.”
Key findings include:
- Surgeons using the Newton technique achieved higher reliability compared to manual methods
- Reproducibility was unaffected by surgeon experience, addressing discrepancies often observed between junior and senior surgeons
- Gap measurement differences between techniques became more pronounced with increased knee flexion, showcasing the consistency of Newton technology along the full arc of motion
“Our company empowers surgeons with real-time, personalized data with our robust platform of advanced technologies,” said Laurent Angibaud, Vice President of Development, Advanced Surgical Technologies. “This research highlights the transformative potential of guided, personalized balancing technology to set a new standard for precision and improved outcomes in total knee replacement surgery.”
GPS and the Newton knee balancing technique are critical components of Active Intelligence® ecosystem of smart solutions designed to provide surgeons with real-time insights and cost-effective solutions for improved patient outcomes. Both technologies are available to surgeons worldwide.
