Osteoarthritis Shoe Insert with Wedge for Knee Pain

Have had several patients with medial OA knee pain who were unable or unwilling to wear knee braces, but wanted to put off getting a total knee. I fabricate a 3/16" lateral heel and sole wedge and glue it to the lateral border of super thin and flexible carbon fiber (cf) plate we fabricate. The cf insert is better than a leather insert because it doesn't deform and will spread the vertical and surface load more evenly. The insert fits into a shoe with little problem. The user can usually can tell immediately if the OA wedge helps relieve their knee pain.
