My relationship with HSS began in the early 90's when my daughter was a physician in training at Cornell. I hurt my shoulder and my daughter recommended Mary Hannafin. Dr. Hannafin was wonderful. She fixed my shoulder and some arthritis in my thumb and it was as good as new. So, when my knee started bothering me 10 years later I called Dr. Hannafin, who recommended Dr. Charles Cornell. Dr. Cornell replaced my right knee and several years later my left knee. He also rebuilt my husband's ankle that was badly broken in a fall and that another surgeon said could not be fixed. About 10 years ago my husband and I retired to Virginia where my daughter practices pediatric critical care, but we always come home to HSS when we need an orthopedic surgeon. There is nowhere else in the world we would ever go!!
