I've had the knee surgery, it was on August 3rd, early in the morning which was good, less time to think about it that day!
The patella was resurfaced, a new femoral component and a larger spacer plus some scar tissue removed. After a rough start I'm doing really well. The pain level is practically zero most of the time since Sunday, I don't even need to take any pain meds , I don't need to use crutches either. It's going much much better than I anticipated which is so so welcome!
I will need a revision of the partial in the right knee but I'm not game to get that done for a while.
