So sorry to hear of your discomfort, I deal with a damaged knee but can't bring myself to a replacement. And I'm older, I'd bet you are pretty young. On your CRPS issue, I don't know how much more damage you have than many others of us. What I can suggest if you can is get a consultation from a Regenerative Medicine MD in your area if that's possible. The larger the area you live, the more of these workers are available.

Here is a link with a smattering of providers and there are more and more entering this world of medicine...so many failed and negative outcomes from these replacements...

As I said a start would be a consultation to see who would do this work for you. I've had it done in other parts of my body and with success in some.
