Is there and crunching/cracking in/around your knee when you move it? Sounds like you displaced your knee cap over your femur, but you should still go see a doctor to be sure. If that is the problem you can expect some inflamation (depends on the situation, worse for some, some barely experience any swelling at all) and probly some pain when doing some things like walking up stairs, etc. Ask your doctor about treatig it, he/she will probably tell you to ice it a lot every day for like 20 min each time, and stretch out your quads and hamstrings, eventually you will want to strengthen your quads more as well, but in the meantime ice it a lot and you may want to try...ummm...shoe inserts i cant remember what they're called, foot orthopedics or whatever, they will help you to walk properly and take some stress off of the injury, talk to a doctor about which ones to get.
