The previous poster said it well, no one "needs" this surgery as it will not kill you if you do not get it, it will not help you walk better like knee replacement surgery will, however, for some people it may help you feel better about yourself.
In the NYC area you have Dr. Elliot Jacobs, he is one of the doctors right here on the forum, and you can't go wrong with him, he is one of the best!
Good luck,
Bob
