Footwear worsens joint biomechanics

Heels and arch supports increase torque on the knee

Casey Kerrigan, MD, MS, Department Chair, Professor of Physical Medicine and Rehabilitation, University of Virginia Health System, discusses her research findings that any type of shoe heel or arch support increases knee varus torque by 26%, predisposing to osteoarthritis. This effect is true for all types of footwear.
