Chondromalacia Patella?

I have this crunching sound when my leg extends from full extension to 15 degrees (i dont know what the standard for measuring angles are, but this is the angle between the top of the leg, and the fully extended position). The odd thing is that there is absolutely no pain that accompanies this. Ive had this or some time, but there has never been any pain associated with it. I had a PT once tell me kneecap wasnt tracking properly, but we theoretically fixed that (it was causing pain that has gone away). It hasnt gotten any worse over time, but really hasnt gotten better either. My other knee makes no such noises. Am i headed for pain soon? How can i prevent that?

forgot to mention that i used to use motion control shoes and orthodic that i soon learned caused all sorts of problems for me (both were recommended by the same PT mentioned above). I had bad IT problems developing, then i switched to a very neutral shoe, and within a week, the pain completely disappeared.

currently under PT for the same condition (but with pain :frowning: )

the person overseeing my rehabilitation (athletic trainer) stated that the noise in and of itself isnt anything to worry about (“most people have some noise”) but pain was when u know something has to be done.

maybe that helps,
