Application of digital technology in rehabilitation of total knee arthroplasty: A systematic review

Purpose: Total Knee Arthroplasty (TKA) aids in reducing pain and improving knee mobility, function, and quality of life in osteoarthritis knee (OA Knee). Techology-based rehabiliation has proved to be promising post-TKA. The objective of this systematic review was to summarize the digital technology after TKA. Methods: The PRISMA Checklist was used for the present systematic review. Randomized and non-randomized studies were included. Joanna Briggs Critical Appraisal Checklist was used to assess risk of bias by two independent reviewers. The data was summarized narratively for the digital technologies utilized. Results: 177 studies were screened from the databases, and 14 studies were included. The risk of bias assessment showed low to moderate-quality evidence. The technologies were divided into 2 broad categories-mobile-based and web-based- although the individual studies had unique technologies utilizing sensors, motion trackers, and game-based and video-based. Conclusion: Various digital technologies focus on providing exercise intervention post-TKA. Clinicians can use face-to-face and technology-based approaches for TKA rehabilitation for a comprehensive subjective and objective assessment post-TKA based on low to moderate quality studies.
