Knee osteoarthritis (OA) is a leading contributor to global disability, with exercise proven to be an effective treatment. Tai Chi is a recommended type of exercise, but it is primarily done in person which imposes an accessibility issue. This study aims to evaluate the effects of an online unsupervised program, when provided with online educational information and exercise adherence support, on changes in knee pain and physical function, when compared to online education control for people with knee OA.
A two-arm, superiority parallel-design, pragmatic randomised controlled trial will be conducted involving 178 people with a clinical diagnosis of knee OA. After completing baseline assessment, participants will be randomly assigned to either: i) "My Joint Education", an education control website containing OA information only; or ii) "My Joint Tai Chi", an intervention website containing the same information as the control, a 12-week unsupervised online Tai Chi program to be undertaken at home 3 times a week, and information about an exercise adherence support app. All participants will be reassessed at 12 weeks after randomisation. Primary outcomes are overall knee pain during walking and physical function using the Western Ontario and McMaster Universities Osteoarthritis Index subscale.
This randomised controlled trial will provide evidence about the effectiveness of the "My Joint Tai Chi" website compared to "My Joint Education" website on self-reported knee pain and physical function for people with knee OA.

膝关节骨关节炎（OA）是导致全球残疾的主要原因之一，运动已被证明是一种有效的治疗方法。太极拳是一种推荐的运动类型，但主要是面对面进行，这存在可及性问题。本研究旨在评估与针对膝关节OA患者的在线教育对照组相比，在提供在线教育信息和运动依从性支持时，在线无监督项目对膝关节疼痛和身体功能变化的影响。
将进行一项双臂、优效性平行设计、实用随机对照试验，纳入178例临床诊断为膝关节OA的患者。完成基线评估后，参与者将被随机分配到以下两组之一：i）“我的关节教育”，一个仅包含OA信息的教育对照网站；或ii）“我的关节太极”，一个干预网站，包含与对照组相同的信息、一个为期12周的无监督在线太极拳项目（每周在家进行3次）以及关于运动依从性支持应用程序的信息。所有参与者将在随机分组后12周进行重新评估。主要结局指标是使用西安大略和麦克马斯特大学骨关节炎指数子量表评估的步行时总体膝关节疼痛和身体功能。
这项随机对照试验将提供证据，证明与“我的关节教育”网站相比，“我的关节太极”网站对膝关节OA患者自我报告的膝关节疼痛和身体功能的有效性。
