That's the rub! Your statement "for informational purposes only and is not a substitute for professional medical advice, diagnosis or treatment" is the problem. I like many others have been there, done that, and see this issue as people in a state of desperation because their medical community has failed them. Many unsuccessful TKR patients were willing to endur the many months of pain, sleepless nights, prescription side-effects, and countless hours of PT only to discover they are worse off than before surgery. In my case I never waivered from any professional recommendations.
My post is about desperate people that have exhausted every professional medical avenue for help.
I may suggest that Mayo Clinic play a more active role, i.e., comment on suggestions that obviously have no merit and lead desperate people willing to latch onto any and all advice.
