The new findings of study, which is continuing to accrue subjects, suggest that children who are OW walk with a peak knee adduction moment 73% (standard speed) to 100% (fast speed) larger than NW subjects. Similar to previous reports in adults who are obese, the children who are OW did not demonstrate changes in the sagittal plane moment, suggesting the lower knee flexion angle is potentially a compensation to maintain a similar knee extensor load, despite an increase in weight. These preliminary results confirm the potential for obesity to alter knee joint contact forces during walking, therefore contributing to the development of angular deformities.
