Dr. Katz replaced my knee 4 months ago. My recovery was slow and painful, but I am convinced it was due to my physiology and inability to take anti-inflammatory drugs. Physical therapy seemed to keep things in a painful holding pattern for me. I have to say that I feel Dr. Katz did a great job on the surgery. In contrast to the person who complained that Dr. Katz didn't provide adequate pain medication, he encouraged me to begin taking it again after I stopped very early on, as he knew I was having great difficulty sleeping. I am improving more and more each week. There is no silver bullet for our problems as we age, and each of our bodies is different and responds to surgery and healing in its own unique way. Dr. Katz and his staff, particularly his patient assistant Meegan, did very well by me and I would recommend them and use them again.
