You probably won't like my response, but my philosophy is that we should not try to save "defective" animals. Nature works only because a lot of things die. If all raccoons (or anything else) survived, they would deplete their own resources and even more would die. The weak and infirm are meant to die and the survivors will produce better, stronger descendants. That's natural selection. It's one thing to try to counter damage done by humans, but nature should be allowed to run its own course. The practice of moving animals around is very detrimental because it spreads disease and contaminates gene pools. If you take an animal out of nature, you deprive other animals of food. My advice is just let it be.
