I've been rehabbing from acl injury and so talk to a lot of people about their knees. I know knees and elbows are very different joints, but every person I talk to who has chronic trouble with their knee (outside of arthritic issues) usually results from diminished range of motion. I agree with Al, go see a doc or even a physiotherapist--who will probably be able to give you exercises on rom and specific muscle work.
