Foot pressure distribution in patients with gonarthrosis.

Background: When standing, leg alignment is controlled by supinating or pronating the subtalar joint, corresponding to valgus or varus deformity of the knee joint. However, in the gait cycle, it is not clear whether the abnormal alignment can be compensated.

Objective: The purpose of this study was to evaluate the control of leg alignment in the latter half of the gait cycle.
