I'd like to think orthopedists would rather be overjoyed at this. My wife had her knee and hip done by a cracking orthopedist, and his primary concern was her quality of life. He even went to the state physicians' board to argue that her hip surgery should be considered necessary rather than elective for purposes of COVID restrictions, so that we could get it done months before it was originally scheduled.

afaik surgeons are able to perform quite a few types of surgeries, obviously the ones working on brains more advanced than ones working on knees it's probably only a few years to transition to a different type of category.
