I just got a tat on the back of my knee, should I be worried about a cracking effect?

I got a tat 2 days ago on the back of my knee. It's not my first tat but I am worried about it cracking throughout it. I got a chinese symbol darkly outlined with color faded inside of it. I understand the color will fade a little until the actual tat heals but because of the excessive bending of my knee it looks like there may be a cracking effect. I have been washing it a couple times a day as well as small amounts of lotion, I am going to switch to A&D ointment tomorrow instead, as much as I can I don't let it rub on things, and keep my leg straight as much as possible. I've considered crutches, but that seems excessive. Perhaps I am just being a little parinoid but I really love the tat and love to show it off, I don't want to end up ruining it. I'll prolly get it touched up after a while but I don't want my new tat to look like crap. Advice Please?
