Is that sarcasm I am sensing?? 😆
My thought was that if I can operate at 90% for 10 years, why risk surgery and the potantial of making it worse? Pain is mostly in your head, This is more of a check-up to make sure things hsve not gotten bad enough to cause perminant and serious damage where I will have to have the whole thing replaced. If I can keep on strentghining the knee and avoid the knife, that is what I am going to do.
