Hi @Luluk , you made me smile. I used to play that little game, too, pretending that my knee was normal . I had lots of good days, so I wasn't 100% sure it was time yet. I decided I would do all the things I wanted to do and I got stopped in my tracks pretty fast and would pay for it for days after. Truth be tokd, my good days were good because I wasn't being active. But that's not living my best life possible. It actually really helped me to make the decision to do the surgery. You're making the right choice In the meantime, I would try to get to the bottom of why your other knee still gives you trouble. Maybe a second opinion is needed. You will need to depend on that knee for your recovery. Keep us posted!
