Knee pain when squatting

Dear Ask The Doctor:
I am 19 years old. weight :90 kg height 5 feet 8 inches. I am having a left knee pain for some 2 months. It occurs only when i climb upstairs and sometimes when i walk down the stairs or when i squat ! what should i do ! i have taken ultrasonic treatment for about a week and wax treatment too, but the pain has not subsided that well .there's no swelling or bruising. x-rays show the bones and joint spaces are totally ok ! it's still there !


 Knee pain is the most common presentation of patellofemoral syndrome. The pain typically is located behind the kneecap and often shows during activities that require knee flexion and forceful contraction of the quadriceps (during squats, bicycle, ascending/descending stairs, jogging or pendants). Pain may be worsen by sitting with the knee flexed for a long period of time, such as while watching a movie, hence leading to the terms "theatre sign" and "movie-goer's knee." The causes are diverse: Overuse (repetitive use or activity), overloading, and misuse of the patellofemoral joint. The suggested strategy for conservative treatment should be as follows: Physical therapy program (exercises and pain control with TENS, ultrasound, ice packs after exercises), anti-inflammatory medication (i.e.: “Aleve”, “Advil”), education  so  you understand which activities avoid because those can aggravate patellofemoral syndrome. Also, and very important, remark the need for extended adherence to the exercise regimen. The physical therapist should educate you about a home exercise program. Allow time for these conservative measures (exercise program) to have an effect, usually 4-6 weeks is adequate for some resolution of symptoms.
