Exactech released the results of new cadaveric study published in the Journal of Experimental Orthopaedics (JEO) for its Newton knee balancing technology.

The study compared the company’s knee balancing tech with traditional manual gap measurement methods used with competing systems, like robotics. According to Exactech, the results showed its Newton knee balancing technique consistently outperformed conventional methods in reliability, regardless of surgeon experience.

Reproducibility was also not affected by surgeon experience, addressing the discrepancies often seen between junior and senior surgeons. Gap measurement techniques also became more pronounced with increased knee flexion, highlighting Newton’s consistency along the full arc of motion.

“This study confirms that Exactech’s 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 Orthopaedic 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.”

Paired with ExactechGPS, the Newton knee tech provides dynamic soft tissue analytics, pre-resection operative insights, and full-range planning. The tool, which launched in August 2024, was designed to simplify, evaluate, and execute balanced total knee replacement surgery.

GPS and the Newton knee balancing tech are components of the company’s Active Intelligence suite of smart solution to offer real-time insights and cost-effective solutions for better patient outcomes.

“Exactech empowers surgeons with real-time, personalized data with our robust platform of advanced technologies,” said Laurent Angibaud, Exactech’s VP of development, Advanced Surgical Technologies. “This research highlights the transformative potential of Exactech’s guided, personalized balancing technology to set a new standard for precision and improved outcomes in total knee replacement surgery.”
