The tendency of orthopedic surgeons to over-operate is frightening. It's not that they're in it for overt bad intentions, like to make a buck off you, but when you're a hammer, everything starts to look like a nail. A lot (most?) of these ortho surgeries have unproven outcomes because they're new as well. That doesn't mean that they're bad procedures just because they are new, but you do have to be careful before going under the knife. Every operation will leave scar tissue and possible other damage that may raise its ugly head years down the road. 2nd opinions are very reasonable.
