I've been a state of pity party regarding my newly replaced knee for the last several months. Now I'm in a zen place, I'm making peace with the fact it will never be as good as I'd hoped. I still limp about 30% of the time, my flexion and extension are fair but not great, and it keeps me from doing much of what I want to do. BUT, it works, doesn't hurt as bad as it did before, I'm a little more mobile than I was, so I'll take it and just do little bits of things. I walk a little, ride my bike a little, swim a little. It's all good.
