Just found out I need a new knee....complete replacement. I,m just curious if anyone has had this done and how the Fed's were to deal with as far as keeping a medical . I know of a collegue who lost his leg and is still flying which is great but ,he went through alot to get back in the seat. I would like to think that it would be easier for me and that I could have the surgery then report it on my next physical. Any comment's ?
