Tarsal Coalition/foot problems

Hi guys My 13 year old son he will be 14 Sept. will be having this surgery in a few months and was wondering if anyone has been through it or knows of someone that has . Is there anything I should be aware about recovery or after ? How will it affect playing baseball and other sports. If you told him he could do only one thing on the field he would want to pitch. Below are two links explaining the problem.
