Patellofemoral pain syndrome may be caused by different causes. Doctors are not sure what actually causes it but they believe that the following are the possible causes-


When you take part in any sports that includes running or jumping, it puts stress on your knee joint. Too much of the sport can result in irritation under the kneecap.

Muscle imbalance or weakness

The problem may start when the muscles around your hip and knee are not able to keep your kneecap properly aligned. If there is an inward movement of the knee during a squat, it can result in patellofemoral pain.


If somehow the kneecap receives any trauma like fracture dislocation, it can cause the problem.


If you have undergone knee surgery it may sometimes cause the pain.
