Last night, while sitting on the carpet with my legs stretched out straight, my kneecap slid out of place and didn’t immediately pop right back in. No pain, just the feeling that something wasn’t in the right place. I didn’t panic and walked over to the stairs to pop it back in place. Why does walking up and down the stairs work? I don’t know but it does. My knee is a little stiff but I was able to run 3.2 miles without a problem this morning. It’s annoying to have a kneecap that does this but at least I’ve figured out how to live with it.
