Estimation of medial and lateral tibiotalar contact forces in flatfoot patients during walking

초록

The tibiotalar joint of the most flatfoot patients has a valgus deformity. Because of the curved deformity, the contact force in the tibiotalar joint would be different from that of normal subjects resulting in pain at the joint. In this study, the contact force in the tibiotalar joint was estimated using a musculoskeletal model. Ten normal and ten flatfoot patients volunteered for this study. We recorded the kinematics of the subjects using a motion capture system, ground reaction force, and foot pressure using a force plate and a pressure mat. The talar dome was divided into medial and lateral regions. Three reaction elements were placed in each region to estimated the contact force in the region. The mean and peak contact forces in the lateral region in the flatfoot were larger than those in the normal subjects. Also, the total contact force of the tibiotalar joint was larger than that of normal subjects.
