Multi-Center Study Testing Special Shoe Insoles to Help Knee Osteoarthritis in Adults 50 and Older

What this Trial Is About

Researchers are studying people aged 50 and older with knee osteoarthritis who also experience foot pain. The study aims to assess the feasibility and early effects of shoe-worn insoles on symptoms and biomechanics at both the knee and foot joints. This multi-center randomized pilot trial is led by the University of British Columbia to explore ways to relieve pain and improve function in affected individuals. Two types of insoles are being tested. One group receives lateral wedge insoles LWIs that have a 6-degree wedge on the outer edge. The other group receives lateral wedge plus custom arch support LWAS insoles, which combine the 6-degree wedge with a tailored arch support made using advanced 3D scanning and printing technology. Participants will wear their assigned insoles in their own shoes for at least 5 hours daily over 3 months. During the study, participants will undergo assessments at the start and after 3 months, including self-reported knee and foot pain, physical and foot function, and walking speed. Biomechanical measurements such as knee moments and foot motion will also be recorded. Researchers will track recruitment, retention, and the time needed to deliver insoles. This comprehensive approach will help determine the insoles impact and the studys feasibility over the trial period.
