Why does an offloading knee brace actually work? It comes down to the knee adduction moment, the rotational force that drives excessive loading onto the affected compartment with every step.
DonJoy OA braces reduce peak knee adduction moment by up to 32% during gait, reduce adduction impulse by up to 37%, and can increase medial compartment joint space by approximately 10% during the impact phase of walking(1,2,3,4).
Unlike NSAIDs, which address pain but not the underlying biomechanics, offloading bracing reduces compartment loading while allowing patients to stay active, protecting the joint rather than masking the problem. 📐
