Robotic hip and knee surgery fails to cut overall risk of repeat surgery
Two major studies by Queen Mary University of London, the University of Oxford and the University of Bristol found that robotic-assisted hip and knee replacement does not reduce the overall early risk of repeat surgery compared with conventional surgery.
Two major studies from prestigious universities in London, Oxford, and Bristol have discovered that robotic-assisted hip and knee replacement surgeries do not decrease the early risk of repeat surgeries when compared to traditional methods. These findings, published in The BMJ, are based on an extensive analysis of over 1 million joint replacement records from the National Joint Registry between 2018 and 2024.
The research aimed to determine if the enhanced technical precision offered by robotic assistance results in improved patient outcomes.
Despite the technology's design to assist surgeons in positioning joint implants more accurately, thereby reducing the possibility of repeat surgeries early on and over time, the studies revealed no overall reduction in the early risk of repeat surgery following either hip or knee replacement. The researchers noted that while robotic surgery is intended to improve implant positioning accuracy, leading to potentially better outcomes, the current evidence does not support this claim.
In the hip replacement study, the analysis showed no overall reduction in repeat surgery or mortality associated with robotic surgery. However, it did indicate that robotic hip replacements were linked to a reduced risk of complications due to implant malpositioning. Nevertheless, this specific benefit did not translate into a lower overall need for repeat surgeries.
Similarly, in the knee replacement study, there was no difference observed in the risk of repeat surgeries between the two methods. The researchers emphasized that while longer-term follow-up is necessary to ascertain if disparities in implant survival emerge over time, the present evidence does not substantiate the benefits of robotic-assisted procedures over conventional techniques.
The study's lead author, Hasan Mohammad, highlighted the importance of this research, stating that it provides crucial independent evidence for patients, healthcare professionals, and policymakers at a time when robotic hip and knee replacement surgeries are being increasingly adopted. The study underscores the need for new technologies to deliver meaningful benefits for patients and offer good value within a publicly funded healthcare system.
