Will knee pain stop me from going into the military?

I dislocated my knee about three years back. I am now starting to feel a slight pain in my left knee whenever I run, juke, or am walking up steps. This doesn't slow me down at all because I run and lift weights about for or five days a week without it bothering me. I am very excited about serving my country, i reallydon'tt want a knee injury to stop that. Also is their any home remedies that could help?
