i also had the hamstring lengthening when i was 2 years old. at first there was improvement but by the time i was 7 i needed both my hips and my knees replace. my knees blew after the lengthening because the hamstrings were lengthened to much. i also used dr. nuzzo and did not have a good experience at all. when we went back to him at the age of 5 he told me that by the time i was 12 or 13 i would be unable to walk and be in a wheelchair for the rest of my life. we needless to say did not go back to him. it is now 14 years after my first operation and i am just like a normal kid. i still have walking issues because of my cerebral palsy. but i play field hockey for my school so dr. nuzzo was wrong. i am still walking and running. when we visited dr. nuzzo we got maybe 5 minutes with him and never saw him. i know you live far away but i siggest the hospital for special surgery. they have amazing doctors and they spend time with you and talk to you. i hope your daughter gets better!
