Anterior knee pain in the young patient?,”Patellofemoral syndrome is a very common cause of anterior knee pain. Symptoms are chronic and associated with activities such as climbing stairs and extension at the knee. Women are affected more often than men. Diagnosis is based on history and examination findings (eg, extension of the knee while compressing the patella)
and treatment involves stretching and strengthening the thigh muscles in addition to avoiding activities that worsen the pain.”
