Hi Alfredo,
This is certainly the way of the future with the rise of regenerative medicine starting to make an impact.
Here is Australia we are still fairly lazy and a lot of steroid is used. I think this will change over time, or at least I hope it does. As you mention the fact we no longer have a Medicare rebate for PRP is a problem so patients choose the free government funded steroid injection over PRP or stem cell options.
I am interested in watching this space.
Where I work in Taiwan the regenerative medicine is much more broadly applied than in Australia.
