A plastic below-knee brace, or ankle foot orthosis (AFO), is usually used after ankle or foot surgery. Your doctor may order an AFO if your child needs extra support in the ankle or foot area.

The brace is made by a certified orthotist. Be sure you find out which orthotist makes the brace so you can call him / her if the brace breaks or needs adjusting. 

Your physical therapist may be involved in the brace fabrication and will direct you to a specific vendor.
