Before the age of 50, I had two total knee replacements at HSS. Dr Mayman absolutely changed my world. The first TKR at HSS was in July 2009, on my left knee. During that surgery, Dr Mayman noticed some problems with my right knee, which had been replaced 6 years earlier in Oregon. He brought in a plastic surgeon to deal with those issues, and in December 2009, I had muscle flap surgery on my right knee at Columbia Presbyterian. During that recovery process, we learned that I was allergic to some metal components in my right knee. This led to a revision of that total knee at HSS in July 2010. Three major surgeries in 12 months, and I am now pain free for the first time in 35 years. There is no way I can ever thank Dr Mayman and his team enough. At 50 I am able to do things I haven't done since I was 15. I actually carry lots of Dr. Mayman's cards and hand them out to anyone who talks with me about knee pain. I live in Ann Arbor, MI and would travel any distance to work with Dr. Mayman. Thank you HSS.
