I had by right hip replaced in 2013. About 18 months later, it began to loosen. I then had the same hip replaced in 2016. Both surgeries were performed by a local orthopaedic group. After my second hip came loose, I spent time on the internet and found both HSS and Dr. Alejandro Gonzalez Della Valle. I called, received an appointment within a week, and met Dr. Della Valle. He informed me that the hip was again loose, but it was not my fault and he could help me. Within ten days, he removed my right hip and replaced it with a new one. Six months later, I am pain-free and able to do all yard chores, and I am once again coaching high school football. I am very grateful for both HSS and Dr. Della Valle.
