A short review on wearable sensors used in the evaluation and rehabilitation of total knee arthroplasty patients

Osteoarthritis is a condition that affects the load-bearing joints leading to functional impairment and reduced quality of life. The knee joint is the most commonly affected joint. It is a condition that progresses gradually. In the initial stages, symptomatic management can be done by conservative treatment. In the severe stage, the primary treatment is total knee arthroplasty. Restricted knee flexion after TKA is a common clinical manifestation and a cause of patient dissatisfaction. Because of this, exercises are important after surgery to gain functional mobility. So, to find the effect of interventions given after TKR, the new technologies can be used to assess the outcomes. Post-TKA surgery to evaluate the range of motion and gait and to make patients exercise using wearable sensors is growing in popularity, as it is easy to use and gives accurate results and feedback to the patient when exercising. The Inertial Measurement Units are made up of a microelectromechanical system. This device collects information about the motions as it is worn on the body, and the data is stored and can be displayed in the software. This gives accurate measures of the outcomes and can be a better assessment and rehabilitation option over the traditional methods.
