I'm seeing improvements here and there on the right knee and it's nearly there in being straightened. The left one still has the muscle contractures, but is straightening out here and there in little bits.
Two milestones came up...
I spent two hours each on a Saturday and a Sunday with Jamie in the back yard doing some planting. While I was sitting at least part of the time, I was helping out here and there in digging holes with something called a garden weasel and removing rocks as I broke up soil chunks. I was able to do more than I could before and just a little pain.
My sister visited with her family and we walked to the building next door which has a playground in back then back to the house. It was a little difficult, but no pain. I probably could walk around the building quite soon.
