You definitely have the clinical signs of patello-femoral syndrome. Given the good quality of the cartilage you may not meet the diagnostic criteria for CM. Remember with these sorts of things often different sources of info give different impressions

I think this is a good thing, Excili. You may of course have some minor changes that aren't detectable on the Wikipedia reference-linkMRI but basically it suggests the patellae are in a reasonably robust condition.

Does it affect the treatment? Not really. I would just keep persevering. As I said in an earlier response the only thing to be sure of is if the tracking of the patellae needs addressing. Otherwise carry on the strengthening exs and be patient.
