An Artificial Intelligence (AI) system that can predict what a knee X-ray will look like in the future could transform how millions of patients with osteoarthritis are treated, researchers have said.
Researchers at the University of Surrey said the developed technology used machine learning to visualise what the knee will look like in a year’s time and score its disease risk.
Osteoarthritis is a degenerative joint disease affecting more than 500 million people worldwide, according to the university.
Prof Gustavo Carneiro said it would help clinicians identify high-risk patients sooner and personalise their care “in ways that were not previously practical”.
The AI system was trained on nearly 50,000 X-rays from almost 5,000 patients – one of the largest osteoarthritis datasets in the world, the institute said.
The AI “outperforms” comparable tools as it is nine times faster and more compact, it added.
Osteoarthritis is the leading cause of disability in older adults, the university said.
Researchers said the work could pave the way for similar tools in other chronic conditions, such as predicting lung damage in smokers or tracking heart disease, allowing doctors to act early.
The university said it would be seeking partnerships to bring the technology into real-world clinical settings.
