I will ask about it, I had already thought about that.
The knee is much better than even this morning. My walking is better (still not perfect), though I am VERY aware of the patella. I am starting to think that if there is any real damage from yesterday, that it is in the actual patella rather than ligaments, time will tell. If I hit that unstable patella with as much force as my face...that might not be a surprise. At least today it doesn't feel like my knee is going to give out or lock up on me, yesterday it did feel that way.
So back to work tomorrow afternoon - depending on how I feel. I've a doctor's appointment and her office is just a few blocks from work. We will see how it goes and if I feel up to the walk from the parking garage.
