This particular cause of knee pain is most often recognized by these symptoms
Patellofemoral pain can result from irritation of the cartilage of the patella which is caused by abnormal contact between the patella and the femur.
The patella, or knee cap, normally glides smoothly in a groove at the end of the femur. Occasionally, an abnormal positioning of the patella leads to inflammation and pain. This problem can be caused by muscle strength imbalance, inflexibility, bony structural differences, improper walking pattern, overuse, or trauma.
If you have patellofemoral pain syndrome, chances are you have fairly common symptoms. You probably have generalized knee pain, especially when you are going up or down stairs, or are moving from a prolonged sitting or squatting position to a standing position. Your symptoms may worsen when you're doing repetitive activities that require bending of the knee including lots of walking or running up and down hills.
The three stretches described here should be done before and after the two exercises.
Stretch 1: hip, thigh, knee (iliotibial band)
Do two stretches, twice a day. Hold each stretch gently for 20-30 seconds while
breathing normally. Relax for 10-15 seconds between stretches.

Stretch 2: calf (gastrocnemius and soleus)
Do two stretches, twice a day. Hold each stretch gently for 20-30 seconds while
breathing normally. Relax for 10-15 seconds between stretches.

Stretch 3: back of thigh (hamstring)
Do two stretches, twice a day. Hold each stretch gently for 20-30 seconds while
breathing normally. Relax for 10-15 seconds between stretches.

Exercise 1: quad sets
Do 3 sets of 10 repetitions three times a day, pain-free. If you experience any
pain or discomfort, do 1 set of 5 repetitions three times a day, working up to
3 sets of 10 repetitions three times a day.
Exercise 2: straight leg raises
Do 3 sets of 10 repetitions three times a day, pain-free. If you experience pain,
do 1 set of 5 repetitions, working up to 3 sets of 10 repetitions three times
a day.
