Foot orthoses and patellofemoral pain: frontal plane effects during running

Evidence supports the use of foot orthoses for PFP, but their mechanism of action is not well understood. New research suggests the effect of orthoses on timing of frontal plane moments may be an important variable.

Running is a common mode of physical activity due to its convenience, relatively low cost, and positive impact on health.1 Unfortunately, the incidence of lower extremity running-related injury has been reported to be as high as 79%, with the majority of these events occurring at the knee joint.2
