Together with the video-based knee osteoarthritis screening model, this system can predict patients%u2019 likelihood of requiring surgical knee replacement in the next eight years with an accuracy rate of 93%.%u201cWe built the first model using data from over 20,000 subjects in the US,%u201d explains Dr Wen. %u201cThen we collaborated with the Hospital Authority, who granted us access to over 5,000 data sets of anonymous local patients. We%u2019ve also been conducting clinical trials in Hong Kong. So far, we%u2019ve recruited over 800 local patients. We%u2019re confident that our AI-powered model will become even more accurate as the database grows, with more local cases.%u201d At the time of writing, a private hospital in Hong Kong has approached the team, hoping to adopt the knee osteoarthritis risk and prognosis prediction system for its patients.JOINT EFFORT
