Knee Replacement Still Working Perfectly After 25 Years

Hi Dr. Warren, In 1995 you did a knee replacement on my right knee at Palms of Pasadena Hospital where I was an employee (and also from Waterbury). Just wanted to let you know that you did such a great job on it, that it is still working perfectly after 25 years. I am now 80 years old and pray it continues to work forever. Thank you for such a wonderful job.
