but was able to heal it with some therapy (not sure how it's possible)...
There are lots of alternative methods/therapies these days that can either put off surgery or prevent it entirely. I know when I broke my arm a few years ago and it didn't heal on schedule, I had some type of electro-stimulation and that helped the healing along and prevented any surgery that I otherwise would have needed.
Unfortunately for Mike, based on almost everything that everyone has said, it looks like whatever he did didn't work for him and he should have just gone under the knife (or laser, or whatever) in the beginning. He and Bob would have been better off in the long run.
