If you want to go into academics, US News is good, otherwise, it is useless. Those rankings are largly based on NIH funding. THere is a reputation factor in there as well, but that, in large, also stems from research and publications.
Mayo is far from a class of its own...even in the academic realm. Some programs typically considered at the top of the academic world Mayo, HSS, HJD, Pitt, Iowa, Case, Cleveland Clinic, Penn, Rochester, and Cambell clinic to name a few. The best community places are Carolinas, Grand Rapids, Akron Summa, Akron General, Greenville, Beaumont, Kalamazoo...at these places, you will probably get a much better operative experience, but much less on the research side.
Overall, there are very few ortho programs that aren't excellent. Go where you think you will be happy and don't worry about the rankings, as most people have different ideas when it comes to rankings. The only way where you trained will have any affect on you life 20 years from now is if you desire to be a program director some day. If that is the case, you would be better off at a research machine like case, mayo, pitt and the rest of the programs mentioned above.
