Wedged Insoles for Management of Knee Osteoarthritis

Wedged insoles are designed to reduce frontal plane knee joint mechanical loads during gait. Specifically, they can alter the knee adduction moment during gait - a variable associated with progression of knee osteoarthritis. In the experimental arm of this study, participants will undergo biomechanical gait analysis to identify the wedged insole that reduces the moments the most. The two options are medial wedge, where the medial aspect of the foot is elevated relative to the lateral aspect, and the lateral wedge, where the lateral wedge is elevated relative to the medial aspect.
