I currently have a broken meniscus in one knee. It hurts. I still have to touch it and think about it before being able to say whether it's the left or the right knee.
That is a common problem. Another problem is determining left and right in another frame of reference. That is to say when you are looking at another person it can be difficult to say which is his right hand. Or when you are trying to unscrew something from an odd angle. For example when you look down at a sink and you try to unscrew the cap at the end of the faucet that holds the screen. From your frame of reference it has to be unscrewed clockwise.
