It does get better... I am doing Exercise Physio as well as normal Physio so I am at the gym once a week for an hour or so... doing stuff like squats, lunges and then leg presses to get strength back..
Kneeling isnt much fun but I can do it.. my only problem is I still have a bit of fluid around the knee and still have a large section which has no feeling at all.. which is really strange. I have certain exercises they want me to do that I need to be on my knees for.. bridges etc.. I dont like them much but figure they must be good for me..
Stairs get easier... I find them pretty simple now but they are much easier in shoes than bare feet.. go figure huh..
