Hi @jenna16bella - I totally understand your frustration. On my first TKR, I was literally on crutches. I could not walk unassisted. They gave me a shot - it didn't help much or for long - and it caused me to have to wait 3 months before they could schedule my surgery. I was frustrated and wished I could have gone ahead and had the surgery up front, but the silver lining of that cloud was that they prescribed physical therapy called "pre-hab" as opposed to re-hab.
It gave me 3 months to do some strength training for my legs, which made my recovery much quicker and easier. I have also been told that if they do everything they can do - including the injections - before deciding on surgery, it is easier to justify for insurance purposes. Did your doctor prescribe "pre-hab" therapy? If not, could you call and ask if PT would be helpful while you wait for your surgery?
