Advita Ortho announced a series of new peer-reviewed research supporting the continued evolution of its Newton® knee balancing technology, advancing the potential for more predictive, measurement-based decision-making in total knee arthroplasty.1-4
Through real-time measurement of ligament behavior across the full range of motion, Newton converts soft tissue dynamics into actionable intraoperative guidance, supporting more consistent and reproducible surgical execution.

“This body of research demonstrates how objective soft tissue data can be processed to enhance the planning of patient-specific targets,” said Laurent Angibaud, Senior Vice President, Advanced Surgical Technologies at Advita Ortho. “As this dataset expands and is reinforced by a growing volume of peer-reviewed research, it becomes increasingly powerful. Backed by our growing intellectual property portfolio5-7, we are enabling more consistent, reproducible planning today, while laying the groundwork for predictive decision-making in the future.”
Across recent publications in leading journals, including the Journal of Arthroplasty, Journal of Orthopaedic Research and Arthroplasty Today, studies demonstrate the impact of integrating real-time dynamic soft tissue measurements into surgical planning. One study established the benefit of considering the soft-tissue laxity as an input to fuel the planning algorithm, while additional research demonstrated the potential for machine learning models to support predictive decisions, including tibial insert selection and individualized balancing strategies.
A newly introduced classification framework further advances this work, providing a structured method to define knee phenotype based on dynamic intraoperative measurements. Together, the expanding evidence base illustrates how objective measurement, machine learning and standardized frameworks can drive more consistent and personalized outcomes in total knee arthroplasty.

“For surgeons, achieving the right balance in a knee replacement remains one of the most complex aspects of the procedure,” said James Huddleston, MD, of Stanford University. “While real-time, objective data across the range of motion from the Newton solution already provides a clearer understanding of each patient’s knee and supports more reproducible decisions, this body of research helps establish the foundation for translating those insights into self-generated patient-specific planning.”
Newton Knee soft tissue balancing is part of Advita Ortho’s Active Intelligence® ecosystem, which provides personalized planning, surgical guidance and data insights across total joint procedures. As the platform evolves, Advita aims to continue to expand its growing data foundation to support future advancements in smart planning, predictive analytics and surgical decision support.
