FuSeARTHRO – Functional Severity Assessments for Joint Arthroplasties

Osteoarthritis (OA) is a disease that can cause significant pain and disability, particularly in older adults. It commonly affects the knee and hip joints, leading to difficulties in daily activities, especially walking, and negatively impacting quality of life. The ultimate treatment for advanced OA is joint replacement surgery, with over 100,000 surgeries performed annually. However, little is known about how the differing functional severity of these patients, including their functional and biomechanical ability to perform general movement tasks (e.g., standing, walking, rising from a chair, stair climbing, etc.). Similarly, there is limited information on the changes in this function during the extended waiting period or following the surgery. Recent technological advancements, such as motion capture systems and wearable sensors, provide an opportunity to gather crucial information in this regard, yet limited research has directly utilized such information. Therefore, the main objective of this research project is to gather functional movement data, both in-clinic and in free-living environments, using cameras and wearable sensors. This data will be collected alongside information on pain, quality of life, and other clinical and surgical outcomes, aiming to create a more comprehensive profile of the functional severity of patients seeking joint replacement surgery for knee and hip osteoarthritis at the St. Joseph’s Healthcare Hamilton orthopaedic clinic. By doing so, this project will enhance our ability to monitor changes in functional severity and determine whether these changes are linked to surgical outcomes or treatment success. This research project aims to improve our understanding of the functional severity of patients with knee and hip osteoarthritis, both before and after joint replacement surgery, by utilizing state-of-the-art technologies such as motion capture systems and wearable sensors to collect comprehensive movement data.
