I have had both of my knees replaced (total knee replacements) by Dr Vasarhelyi and have had the very best results ever. I can now run and climb stairs and have not so far found a distance that I cannot walk. I know that I am very lucky to have had such a skilled surgeon and I also followed all of the directions that I was given including doing physio exercises the day after surgery in the hospital. Good results are a combination of having a good surgeon, a good attitude and hard work to regain your flexibility. Dr Vasarhelyi is a very good surgeon!!
