Ozone injections of knee OA

[donwinder]

I ran into this article about ozone injections for OA. Looks to have promising results.

-Any experience with this? Does it really help at all?

-How does insurance feel about it? We do PRP injections and insurance is useless for that injection.

-Is the required equipment expensive?

Thanks for any input.
