Tips for shaving with a knee injury?

For anyone who's ever dealt with a bum knee and tried to shave you know its a pain in the ass. Anyone have any tips for shaving your bad leg (and other things lol) when you have limited mobility? I just kinda feel disgusting not being able to shave and I'm too poor at the moment to be able to pay to get a wax right now.
