What Causes Knee Pain While Extending The Leg?

My knee has been hurting for four months. I am very flexible, but because of my knee i can only bring my leg up laying on the ground up to 90 degrees. My knee cap starts to shake real bad, as i try to extend my knee, and flex my hip joint. It hurts to walk down the stairs, Basically to use it against gravity. Xrays, and an MRI didnt show anything. I need help!
