Has anyone experienced success with stem cel treatment on knee joint bone on bone?

Hello Anon

Thank you for writing.

An orthopedic surgeon can give you a lot of information about this new procedure. We have an article on this treatment here (it focuses on the spine but the topic is the same) cut and paste - https://www.empowher.com/wellness/content/could-spine-surgery-take-away-your-pain
There is also a company called Regenexx that offers a lot of information - bear in mind it's a pharmaceutical company - cut and paste here: https://www.regenexx.com/the-regenexx-procedures/hip-surgery/

I hope others in our community can tell you of their experiences-Best,
Susan
