A Knee pain and mobility limitations are among the most prevalent musculoskeletal disorders affecting individuals across all age groups. This paper presents a non-invasive smart knee support system designed to provide real-time pain assessment, mobility enhancement, and preventive intervention. The system integrates wearable sensors, including motion and pressure sensors, to continuously monitor knee joint activity. An intelligent algorithm processes the collected data to estimate pain levels and detect abnormal movement patterns. Based on the analysis, the system delivers immediate haptic feedback to guide corrective actions. Furthermore, the integration of Internet of Things (IoT) technology enables remote monitoring, cloud-based data storage, and long-term analysis of joint performance. Experimental results demonstrate improved user awareness, reduced strain, and enhanced mobility. The proposed system offers a proactive, user-friendly, and efficient solution for personalized knee care and rehabilitation.
