Coachie,
What a year for you, and for me, and for others. Now you have hope, and are getting back your old self. That is so great to hear.
We all knew there must be something wrong to fix in your case. You knew all along it was in the kneecap. What a process it's been to put together the information so that the doctors got it.
Anyhow, you're four weeks away, and I can't imagine recovery will hold a candle to what you've already been through. I feel confident that you're headed for good times.
My knee is still stiff, still a significant effusion in the joint, but rather than comparing that knee to the healthy knee I remember, I compare it to options like wheelchair, knee fusion, the 70 degree bend I was stuck at in February, etc. It's all about seeing the glass half full, isn't it?
