I had a knee replacement done by Dr Scott Martin and I thought he was the best not only is he a cool guy he is an amazing doctor. He has a lot of confidence as he should he is the best at what he does, He gave me my life back when other doctors were afraid to work with me because I also have AVN but not him he looked at me and said no problem I will help you and he did There is no other doctor to go to if you need a knee replacement
