re: Platelet Rich Plasma (PRP) Injections.

The evidence that it actually works is spotty at best. In 10 years this will all fall to the wayside as another medical fad. Everyone is looking for the latest and greatest technology, but most of these things don't pan out - that's why insurance doesn't pay for it. And the reason you hear about professional athletes getting it is because they are willing to try anything to get better faster, and $500 cash for each injection is nothing for them.
