Hey let me add my wishes for your complete recovery soonest!!
Since you don't yet know the complete damages, I'd get a lawyer, or at least talk to someone here that volunteered more info. In no way should you settle on medical or anything else. It could take a lot more tests to see what's wrong with the knee area.
Also, I'd take off all the accessories you can that are still good. I can't see them totaling the bike, but talk to Wade about his experience.
