For the first time in over 15 years I am able to walk without pain. I am so grateful for Dr. Parks and HSS for giving me back my "LIFE". I never expected this process to go so smooth. The professionalism and warmth of Dr. Parks and his staff gave me the courage to do this. I had my first knee replacement in February 2016 and seven months later replaced the other knee. To be able to walk and go up and down the stairs (without a cane, etc.) is unbelievable! Thank you Dr. Parks and HSS.
