In March 2015 I had a full left hip replacement, prior to the surgery I was in a great deal of pain and had limited mobility. Dr. DiFelice and the staff at HSS were terrific! After my surgery the pain was gone, my mobility is back and 6 months later I was on safari in Africa riding an elephant! I'm in the green jacket and I AM back in the game! Thanks Dr. DiFelice! You and your staff were wonderful!
