Robotic Skeletons In Knee Rehabilitation: Enhancing Mobility Through Innovation

Abstract

Robotic skeletons, or exoskeletons, represent a major innovation in modern rehabilitation, particularly for patients recovering from Total Knee Replacement (TKR) surgery. These wearable robotic devices assist in movement, reduce physical strain, and promote functional recovery by enabling controlled and repetitive therapeutic exercises. The technology is classified based on power source, body region supported, control mechanism, and application purpose, encompassing active, passive, upper limb, lower limb, and full-body systems. In knee rehabilitation, robotic exoskeletons enhance mobility, muscle strength, and range of motion through precise and adaptive motion assistance. Clinical evidence highlights their role in accelerating recovery, improving patient independence, and elevating overall treatment outcomes. However, challenges such as high cost, limited accessibility, and technological constraints remain barriers to widespread adoption. Future directions include integrating artificial intelligence, virtual reality, and Industry 4.0 technologies to enable personalized, data-driven, and immersive rehabilitation experiences. Overall, robotic-assisted rehabilitation demonstrates great potential in transforming conventional therapeutic practices and improving quality of life for individuals with orthopedic and neurological impairments.
