Hi I'm 16 female and recently I have notice that my right knee how I walked my knee buckles and my feet would be pointing outwards. Also I would get pain all around my knee and sometime clicking noises running, walking up and downstairs, sitting and jumping. Can I ask how can I treat it and what could this be?

You need to see a Physician - a knee that buckles is dangerous and no one can diagnose the problem without actually examing you.
