If you're in Boston and have time for a second opinion here, go to The New England Baptist hospital! (I did not and I regret it and will go there if I switch doctors or have my other knee done). They are the gold standard for orthopedic care, moreso than even MassGeneral or the Brigham ... my surgeon is Dr. Andrew Ayers in Peabody, but I can't stand Salem Hospital so won't have any more surgeries by him.
