Brief Summary

Symptomatic osteoarthritis (OA) of the knee affects approximately one-fifth (\~300K) of Singaporeans aged 50 years or older, with the disease prevalence increasing with age. Patients with advanced knee OA and severe disability often require a total knee replacement (TKR) surgery. With an ageing population and the high prevalence of obesity, the annual number of TKRs is projected to rise. Thus, innovative care models are urgently needed to improve patient outcomes while managing or reducing the economic burden of this common and costly public health problem. Unmet Need: Conservative treatment through physiotherapy rehabilitation is a key intervention, but significant access limitations result in unnecessary TKRs. For patients with knee OA, consensus guidelines are unanimous in recommending education, exercise, and weight management (if required) as first-line interventions. Physiotherapy rehabilitation incorporates these three first-line interventions and is a widely advocated and evidence-based component of OA management. Despite this, international evidence suggests that these core interventions are often under-utilized, with only 20-40% of community-dwelling older adults with knee OA receiving them. Locally and worldwide, suboptimal care from rehabilitation non-attendance is prevalent and costly: available research suggests that at least a quarter of TKRs could have been avoided with optimal care. Thus, to reduce the economic burden of OA, there is a need to develop innovative and flexible rehabilitation strategies. A mobile health (mHealth)-based program is a likely solution to address this unmet need, but local contextualization is needed. Against this background, an mHealth-based OA self-management program may be a feasible solution to deliver guideline-based interventions, with minimal involvement by healthcare professionals. Whilst several app- or web-based OA self-management programs are available, few have undergone rigorous randomized controlled trial (RCT) evaluation, and still fewer provide detailed instructions to enable self-directed exercise (in particular, muscle strengthening exercises) - despite the evidence that exercise is the cornerstone of knee OA management. Furthermore, the reach and adoption of these programs in Singapore is limited as they are designed for English-speaking patients from Western cultures. Hence, whilst there are potential benefits in harnessing technology-enabled programs, these data emphasize the need for local co-design and adaptation to suit the Singapore context and to facilitate adoption. Thus, the investigators have, through an iterative user-centered design process, developed Managing Osteoarthritis of the Knee using Therapist Technology Optimized Rehabilitation (MOKneeTOR), a blended digital rehabilitation program integrating an initial face-to-face physiotherapy assessment and an mHealth-enabled exercise and self-management program designed to promote first-line interventions (education, exercise, and weight management where indicated) for patients with knee osteoarthritis.
