Biomechanics and Clinical Outcomes in Responders and Non-Responders

During data collection, markerless motion capture systems will be placed around the area of interest. The markerless system does not require markers to be attached to the participant's body. The data collection will include: 1. Demographic information such as age, sex, body height, body weight, body mass index, medical history, medical diagnosis, and the Kellgren-Lawrence score. 2. Patient-reported questionnaires such as the numeric pain rating scale, knee injury and osteoarthritis outcome score, Western Ontario and McMaster Universities Osteoarthritis, and Depression, Anxiety, and Stress Scale - 21 Items. 3. Clinical assessments such as the Varus-valgus laxity test, Foot posture index, Range of motion, Muscle flexibility, and Muscle strength. 4. Functional tests such as the Timed up and go test, Five times sit-to-stand test, Four-meter walk test, and Bipedal quiet stance test.
