I have been working with Dr. Knowlan for many years due to my degenerative arthritis in both of my knees. When the pain and the loss of function became intolerable, we decided it was time for the replacements. His knowledge, experience, and communication were essential in determining which knee to do first, and how soon after to do the second knee. I call it my medical miracle. I am amazed at the outcome. I feel like I am 20 years younger, because the limited function and pain made me feel 10 years older than I actually am. Sometimes I forget how painful and difficult it was to use my knees. Yet, every now and then I realize that I’m walking up stairs without pain, and I smile! I even have to remind myself that I don’t have to use the hand railing. I can stand, walk, and play golf without pain. I can shop without pain. At the end of a long day at work, I walk out to my car and realize how much energy I still have. It has been a life changer for me. I am grateful every day for my knee replacements. Dr. Knowlan is my hero! That may sound a little over the top, but my life is so much better now.
