Structural foot characteristics in people with midfoot osteoarthritis: cross-sectional findings from the Clinical Assessment Study of the Foot: Structural foot characteristics in people with midfoot osteoarthritis: cross-sectional findings from the Clinical Assessment Study of the Foot.

People with midfoot OA have a flatter foot posture compared with controls. Although caution is required when inferring causation from cross-sectional data, these findings are consistent with a pathomechanical pathway linking foot structure to the development of midfoot OA. Prospective studies are required to determine the temporal relationships between foot structure, function, and the development of this common and disabling condition.
