For those of you that wanted to know what's what:
Good news is that I don't need a replacement, or even a partial replacement, but I do have to have surgery on a more minor scale. The MRI showed both the medial and lateral meniscus are torn, and they will have to be repaired, I had the medial done in both knees 20+ years ago, so here we go again. I'm scheduled for the 19th of this month and it will be an outpatient procedure by scope, so I'll be back home and dancing the jig by the end of the day. Well - maybe not dancing, but at least I'll be home.
So that's it. Thanks to all for the prayers and positive vibes - they worked!
