The objective of this study was to assess the kinematic and kinetic effects of wearing a lateral wedged insole on the knee joint moment during gait, specifically in the frontal plane, in knee osteoarthritic patients. Motion analyses were conducted with (1) a three-dimensional motion analysis system and (2) a ground reaction force analysis using force platforms when subjects walked under two different conditions : bare foot (B) and a heel valgus wedge with an elevation of 6.35 mm (W). No obvious differences among conditions were found for the knee joint varus moment and subtalar joint valgus moment during the stance phase of gait. The actual segment angles at the subtalar and knee joints did not show any changes due to conditions. These results indicate that the indication and limitations of lateral wedged insoles should be ascertained in the future with a larger study to assess the difference in the effects of lateral wedged insoles among knee osteoarthritic patients.
