Here is my April update. I am a little over 5 months out. I am still able to see improvement when I walk, but my knee is still not feeling "good". I am seeing the pain and swelling lessen but not to a point I can live with. The knee cannot take a lot of activity at least right now. A 5 mile bike ride was okay but a 10 mile got me sore for 3 days. I have backed of everything but walking and hoping it is a matter of time before I can do more. I am hoping I can build up to it. The doctor says this can go on up to 6-7 months. I will see if he is right but it is hard to trust my knee or him. I am preparing myself for dealing with a bad leg the rest of my life but I really feel this may just get there. It has taken much longer than I (and my doctor I am pretty sure) thought, so I am not entirely confident in that. Time will tell. I will post again at the end of May FWIW. My one big complaint having gone through this is being in the dark about what is happening to me. The doctor should have been much more up front with me about what I have been dealing with and what I might be facing for an outcome. At 6 months after the original TKR I was struggling but I was told I was fine. Just 5 months later, I was told I needed a new part. That is why I am posting here. Hoping at least others might not feel as lost. This is hard to go through.
