The development of medial knee osteoarthritis (OA) has been attributed to overloading of the medial compartment articular cartilage [1]. Therefore, treatment strategies are often focused on reducing medial compartment loads. Gait modification represents a non-invasive method for achieving this goal. Previous studies have shown that a variety of gait modifications (e.g., toeing out, increased medial-lateral trunk sway, walking with medialized knees (i.e., medial thrust gait)) are effective in reducing the external knee adduction moment [e.g., 2–4]. Although the external knee adduction moment is often used as a surrogate measure of medial compartment force, a recent study showed that reductions in the external knee adduction moment do not guarantee reductions in medial compartment force [5]. Therefore, direct measurements of changes in medial contact force are important for determining the effectiveness of gait modifications.
