I have had a lot of trouble with my left knee for the last three years. Usually, it takes the form of pain going up and down stairs and stiffness. Today, it is not hurting or stiff, but is emitting a sound every time I take a step that sounds disturbingly like whirrrr....click.
I do not think that this could possibly be a good sign.
