NYCFoot,
Last article I saw, HSS was ranked #1 in the world for orthopedic surgeries for the 10th year in a row or so, so given your location I would definitely look into going there.
I live a hop skip and jump away on LI, but unfortunately when I needed my ankle surgery no doctors took any insurance, the hospital does, but not the doctors. Dr. Kennedy is famous for his ankle 'prowess' but I am sure there are other foot specialists there as well.
Just an fyi .. my brother was operated in there a few years ago for a rare injury with his achilles, no other hospital would touch it, and aside from his amazement that his neighbors were Princes and Kings from other countries, he did say that the food was amazing, gourmet quality. Not bad getting not only the best doctors/hospital in the world but good food too!
Good luck!
