Abstract: Objective: To conduct a scoping review of the application of mobile health technologies in home-based rehabilitation of patients with Knee Osteoarthritis (KOA), in order to provide a reference for medical personnel in related fields to identify the characteristics and current application status of mobile health technology. Methods: According to the JBI scoping review methodology framework, nine Chinese and English databases were searched from their inception to July 18, 2025. The included literature was then summarized and analyzed. Results: A total of 32 literatures were included. The types of mobile health technologies applied in the home rehabilitation of patients with KOA mainly included video conferencing, remote rehabilitation systems, applications, social software, and networking platforms. The rehabilitation contents involved knowledge guidance, exercise guidance, dietary guidance, condition assessment, follow-up management, etc. Outcome indicators included therapeutic effect indicators, self-management indicators, psychological indicators, doctor-nurse-patient experience indicators, and other indicators. Conclusion: The study has shown the effectiveness, feasibility, and acceptance of mobile health technology for joint protection and pain management in individuals with KOA, and it has significant effects. Future research directions may involve further integration of intelligent algorithms and real-time monitoring technology, as well as the development of digital tools incorporating a rehabilitation model that combines traditional Chinese and western medicine approaches.
