This may not apply here, but there was a news article where a doctor said it was okay.
LinkPersonally I don't see that much of a problem with it. Sure they could have gone through therapy, but there are a number of reasons not to such as financial (amputation cheaper than therapy in the long run) and stress (quick fix vs. long fix). Now of course I would rather not willingly amputate any limbs, but some people feel it is right. There is a difference between doing this at the customer's request and doing this because they feel like it. Of course the latter decision leads to malpractice lawsuits which may also be more beneficial in the long run.
