U.S. News & World Report provides great tool for obtaining a list of the best orthopedic surgeons in any given area of the United States. Best of all, these "Top Doctors" who appear on the list have been nominated by their peers. Based on the top orthopedic surgeons listed for the New York City area, in my opinion the listings appear to be true. (You can also use the tool to find the top doctors in other specialties, also.) http://health.usnews.com/top-doctors/directory/best-orthopedic-surgeons Just enter your zip code into the search engine on the left and indicate a distance you are willing to travel. Oh one more note... This list is a good starting point, but always inquire how many total knee replacements the doctor performs each year. An orthopedic surgeon who does mostly back surgeries is probably not the guy you want to replace your knee.
