@Shortstuff26 The steroid injections worked great on one knee and hardly at all on my other knee. I was able to go almost 2 yrs of having steroid injections on my Rt knee. I knew it was time for surgery when the pain was severe even at rest and I couldn’t walk far at all! I might have been able to go longer but I can’t take NSAIDS.
And the people that have said they would never have a TKR might eat their words if they experience the pain and debility of bone on bone pain and having to sit out on normal activities that they would normally do. Truly affects your quality of life.
Ortho docs used to discourage younger people back when replacements only lasted 10-15 yrs because they knew they would need replacements again in older age. But now with the newer hardware, replacements are lasting so much longer.
I agree with everyone else about getting a second opinion.
As far as continuing your running after TKR, I think it depends on the Dr. I know they say the hardware won’t last quite as long in runners.
I have known many who have done well having both knees done at same time. I am personally glad that my knees went bad 5 yrs apart and I wasn’t faced with that.
As far as your fear, the fact that you have good support will help sooooo much. Try not to be fearful. There are great medicines now to control pain and the actual surgery is the easiest part of having a TKR. The recovery is the challenging part and everyone has a different experience.
Best of luck to you and will keep you in my prayers!
