Abstract：
Clinicians worldwide have embraced Ponseti\'s nonoperative approach in the treatment of clubfoot, primarily due to ubiquitous reports of successful outcomes. A crucial component in this measured success, has come from researchers assessing long-term physical function following nonoperative treatment. Gait analysis has been instrumental in objectively evaluating lower extremity kinematics and kinetics while plantar pressures demonstrate the load bearing patterns experienced in the foot. As technology improves, our ability to evaluate function can take place both in the laboratory setting, and in the community. For over 20 years, our institution has been studying the gait patterns of children treated for clubfoot. After adopting the nonoperative approach, we established a prospective research program that has allowed us to study functional outcomes in the very young walker, through growth to adolescents, and finally at skeletal maturity. We have seen over 450 children treated for clubfoot in the Movement Science Lab, for over 1,250 gait assessments over the span of this study. Early results in 105 children (154 feet) treated nonoperatively for clubfoot, showed 56% of children had normal sagittal plane ankle kinematics, however an incidence of 48% of Ponseti feet had increased dorsiflexion in stance phase, leading us to wonder if this was the result of the tenotomy. Intermediate follow up at age 5 years, showed that the incidence of increased dorsiflexion was reduced (24%) and ankle power did not appear to be affected (P>0.05 compared to controls). The research highlighted in this paper presents the application of functional evaluation through growth and the long-term effects of nonoperative treatment on gait and function. This is a review of the functional outcome studies from our experience at Scottish Rite for Children.
