Knee osteoarthritis (KOA) is a common degenerative disease with no cure, but affects 10% of the Hong Kong population. KOA also jeopardises mental wellbeing, as patients with KOA are at a higher risk of dementia and depression. Besides this, it affects mobility for social interaction and self-care, causing isolation and reduced self-efficacy.

Unfortunately, KOA is a complex disease and an accurate prognostic model is lacking. Furthermore, delayed diagnosis means that KOA patients miss the golden period to reverse the progression of the disease and may suffer irreversible damage to their knee joints. Therefore, the current flawed approach leads to poor treatment outcomes for KOA patients and hefty annual health costs of HKD 1.4 billion, both of which are largely preventable.

In response to the foreseeable ageing population, we developed a state-of-the-art AI-based KOA prognostic system for better disease management and a mobile application for patient self-management. The prognostic system will be implemented in different healthcare settings, e.g. our basic version of AI could provide KOA risk assessment and screening at the community healthcare centers with simple checkup procedures.

Our advanced version of KOA prognostic AI system provides detailed analysis on medical images, biochemical markers and electronic health records of the patients at the secondary healthcare. This system not only serves as a triage system for surgical planning, but also generates results to construct optimal and personalised therapeutic plans.

We also develop a mobile application to allow KOA self-management on the palm for the general public. The app provides quick AI-based KOA risk assessment with a short questionnaire and a novel video gait analysis that examine the users’ walking pattern captured by their mobile devices. Following closely to international clinical guidelines, the app also provides personalized health education on exercise and lifestyle modification. Users could also find suitable clinicians for help via our platform.
