Design and Prototyping of an Robotic Exoskeleton for Rehabilitation After Total Knee Arthroplasty

The most increasing trend is to utilize total knee arthroplasty (TKA) as a surgical solution to relief the effects of severe arthritis. Researchers have become interested in replacing an efficient robotic assisted method in place of traditional physiotherapy post-TKA. The effectiveness of these devices in reducing recovery time, improving mobility, and decreasing the risk of future injuries is entirely reliant on the design and functionality of the proposed robotic system. The main objective of this study is to propose a streamlined and organized process to design and construct an exoskeletal robotic system for post-TKA, drawing on biomechanical investigations. In the design of a system for safe human-robot interaction during rehabilitation, it is crucial to prioritize compatibility and reliability as important parameters. This research proposes a framework that combines physiotherapy protocol with biomechanical analysis of human motion to address these issues. An experimental investigation was conducted on the built prototype to assess the performance of the suggested design framework.
