Dear Dr. Crutcher, This is a long overdue communication of thanks, gratitude and feedback. In July of 2006 I had both knees replaced with the Triathlon Total Knee System. Ever since then, I am 100%. I have no limitations or reservations at doing any activity I wish to do. I am 69 years old. I enjoy going to the gym, running, swimming, biking, and climbing. My knees, are probably the strongest part of the whole of me. Dr. Crutcher is the best mechanic and medical professional in the business. You made all the right decisions, choice of product, your skill and wisdom. You are the man. To the whole staff, I am deeply grateful. I plan to continue to put these knees to the test and get every ounce of life out of them. Every day I think of how lucky I am and you are at the top of my list.
