knee

I am a 36 year old female.
I fell down in my driveway 9 months ago.
I hit the ground with lots of force on my knee.
I went straight to the emergency room to have it looked at.
They x-rayed it and said there was no broken bones. 6 months later I went to an othropedic doctor, because I still can not place ANY pressure on the front of my knee.
He did another x-ray and said that there were no broken bones and that it was just a bruse.
It has now been another 3 months since that visit and I still have BLINDING PAIN. Can this really be a bruse for this long.
The orthopedic doctor said that that he suggestes that I don’t put any presure on it.
It has gotten to the point that I can hardly stand on my leg at all.
Please let me know who I should see about this.
