    Advancements in Robotics and Navigation Have Little Impact on Infection Risk in Hip Replacement Surgery, Study Finds

    A recent study published in The Journal of Bone & Joint Surgery has revealed that the use of robotic-assisted surgery and surgical navigation techniques does not increase the risk of periprosthetic joint infection (PJI) in patients undergoing total hip arthroplasty (THA). The findings provide reassurance to both patients and surgeons regarding the safety of these innovative technologies.

    While computer navigation (CN) and robotic assistance (RA) have become increasingly popular in THA procedures, questions have been raised about their potential impact on infection risk. The study, conducted by Dr. Alberto V. Carli and colleagues from the Hospital for Special Surgery in New York, aimed to investigate this concern.

    The researchers analyzed the data of nearly 13,000 patients who underwent primary THA between 2018 and 2021. They compared the rates of PJI in patients who received THA with CN or RA to those who had conventional THA without these technologies. By utilizing propensity-score matching, the study accounted for other risk factors and ensured balanced groups for comparison.

    The results revealed that both CN and RA were associated with slightly longer operative times, with RA leading to an additional 11 minutes compared to conventional THA. However, the incidence of PJI was similar across all groups. The rates of infection were 0.4% for CN, 0.4% for RA, and 0.2% for conventional THA.

    These findings are particularly significant considering the widespread concerns about the potential risks associated with prolonged surgical times. The study suggests that despite the increased complexity and additional resources required for CN and RA, the risk of infection remains comparable to that of conventional THA.

    The researchers acknowledge some limitations of the study, such as the low overall rate of PJI in their specialized orthopedic surgery center. Nevertheless, the results provide encouraging evidence that the use of CN and RA does not significantly impact infection risk.

    As technology continues to advance, the use of robotics and navigation in THA procedures is expected to increase. The study’s findings contribute to the growing body of evidence supporting the safety and effectiveness of these technologies. While further research is needed to explore long-term outcomes, the study offers reassurance to patients and surgeons considering these innovative approaches.
