The hip seems like such a bad example to me. First of all, who do you think needs hip replacements? It's not young people; surgeons don't even like to do them on young people (and to a joint replacement surgeon, "young" is under 60) since there's a good chance they'll outlive the joint itself. And it's a one-time cost for a surgery that increases an old person's independence vs an ongoing cost of palliative care (whatever that means) and having to provide more care for someone who has a potentially treatable disability. Hip replacement is considered "the surgery of the century" - the 20th century that is, because it is one of the most successful in terms of function and satisfaction provided to patients.
