Pedobarographic changes in Ponseti-treated clubfeet with and without anterior tibialis tendon transfer: changes due to growth and surgical intervention.

The aim of this study was to identify significant changes in pedobarographic parameters attributed to growth versus growth and surgical intervention for uninvolved feet, clubfeet (CF) subjected to anterior tibialis tendon transfer surgery, and unilateral nonsurgical CF. Participants underwent foot-pressure analysis preoperatively and 3 years postoperatively. Six parameters related to the lateral midfoot showed increases for uninvolved and nonsurgical CF, whereas CF subjected to surgery decreased. Transferring the anterior tibialis tendon resulted in improvements beyond typical growth and in a more balanced foot postoperatively. These changes are not simply changes in the peak pressure, but changes in force/pressure over time in the lateral foot.
