Abstract
Total knee arthroplasty (TKA) continues to be associated with a patient dissatisfaction rate of approximately 20%, mainly due to alignment defects and ligament imbalance. To address this issue, computer-assisted surgery was introduced to improve cutting accuracy. However, its clinical benefits have been difficult to demonstrate because of cumulative intraoperative errors and the use of non-personalized alignment strategies.
In this context, robotic assistance has emerged as a major advancement. It offers improved reproducibility combined with the ability to personalize procedures to each patient’s characteristics. Currently, three bone preparation modes are available: rotary burr or robotic arm-controlled effectors, including cutting guides and real-time adjusted robotic saws.
This technological evolution is accompanied by significant economic and scientific momentum: the global market is growing rapidly (+20.9% in 2024), with TKA robotization rates estimated at 50–60% in the United States, while France remains behind (≈5% of procedures). Scientific publications confirm the potential of these solutions to reduce early revisions and improve patient satisfaction.
Although the technology is now mature and reliable, long-term studies and national adoption strategies are essential to optimize its integration into clinical practice in France.
