Our German Shepherd Frodo had somehow pretty much destroyed his knee, and because of his size our vet recommended TPLO procedure. The surgery went well, but weeks later there were draining fistulas in his leg, and ultimately it was determined that he was trying to reject the plate. Yet another surgery then to remove the plate. The total for all of this was about $5,000, of which insurance paid over half. As I tell people, my dog has better health insurance than many people in this country.
