Abstract

Pes planovalgus is a common deformity in children and calcaneal lengthning osteotomy is an useful operation. We performed the operation on a 9-year-old female patient with bilateral planovalgus feet and evaluated her pre and post operative states.<BR>Three- dimensional gait data was collected with the ANIMA motion analysis system (MA2000). Four force plates (MG-1090) were used for kinematic analysis. The data of the patient was compared to our data for normal adults before operation and at six months after surgery. The kinetic and kinematic parameter had normalized after treatment. Improvement of feet alignment caused hyperextension of her knees. We have to observe the course of her knees carefully hereafter.
