Is regenerative medicine actually repairing tissue or just helping symptoms?

I’ve been trying to understand this better and keep running into mixed explanations.Some sources describe it as supporting actual tissue repair, while others frame it more as improving function and reducing inflammation. I’m guessing the truth is somewhere in between, but it’s not very clear how much of each is actually happening.

It also seems like different providers approach it differently, which probably adds to the confusion.

If anyone here has a clearer understanding of how this works in practice, I’d really appreciate the insight.
