Good Luck to you. 
It's a simple operation, don't be too tense if not ur BP too high
cannot operate le.. hahahha..
I had 2 leg operations before(not on kneecap though), one is to
inplant the metal plates and screw, another to take out those
stuff.. hahaha.. It's pretty okay de.. After some physiotherapy
after the operation, you'll be fine again. I remember that time in
the same room, there're other patients who had the same operation
like what you're going to have, and they are pretty okay after it.
