Project summary

About 100,000 knee replacements are performed each year in the UK to help people with severe knee osteoarthritis. Although most are successful, 1 in 5 patients experience chronic pain after the surgery and 1 in 23 patients will need more surgery within 10 years, due to complications such as the replacement becoming loose. I will develop a computer tool to better understand why a knee replacement may lead to chronic pain after surgery or the need for more surgery. The tool will learn to predict poor outcome based on knee X-ray images, clinical and patient-reported data. For patients and doctors to benefit from the tool more quickly, I will develop guidance and strategies on how to bring such a tool into the clinic. The tool will facilitate informed doctor-patient decision-making and enable personalised treatment, such as preventive pain management, for patients at risk of poor outcome.
