Update at 7 weeks. I went back to work on site on Monday. Walking over 3000 steps per day. Elevator was out so forced to do more stairs up and down. The knee is very sore. I'm not liking how loose the knee seems, like when you have a blown ACL, forward and back but no ACL-like with sideways instability. It is stable laterally in other words. I'm told that's normal but it's still disturbing. X-ray in 10 days. Only been doing stretching and bike once a day because I have 3 hours of driving so no time.
