Effect of the Center Bridge-Type Knee Orthosis on the External Knee Adduction Moment During Gait in Patients with Knee Osteoarthritis

These findings suggest that in patients with OA, achieving EKAM values comparable to those in healthy individuals would require a valgus corrective moment at least 5.34 times greater than that produced by the center bridge-type knee orthosis. Clinically, this indicates that current orthotic designs may provide insufficient mechanical offloading, and that further structural refinements are required to enhance valgus correction and achieve more effective reduction of medial knee loading during gait.
