How can i permanently cure and strengthen my knee from patellofemoral syndrome?

Strengthen quads: 'Permanent cures' from kneecap pain are difficult. Depending on the 'wear' of your patellar cartilage, patellar instability, 'Q' angle, weight and quadriceps strength/ tone and your motivation... My advice without knowing anything about you is this: strengthen your quadriceps as much as u can and keep your weight down( high school weight)...See an ORS who treats patellofemoral pain/ instability.
