ITB syndrome?

I have had kneepain for over 2 years now (left knee). I have a misaligned knee (subluxed patella and shallow trochlear groove) and had a scope (LR) 9 months ago to prevent dislocations. The LR failed. But apart from the malalignment problem I also have pain on my lateral femur condyle. The pain increases while running and after running, walking stairs, walking up&donwhill, getting in&out of the car, squatting, cycling, kneeling, swimming... My OS says it's because of the malalignment I keep having this pain and suggested a Fulkerson. I've looked it up on the net and seems my symptoms match ITBsyndrome. I can't ignore the fact I have a misaligned knee, but could it be ITB? I've had 4 cortizone shots which all give me some relief but within 6 weeks pain reoccurs. Resting doesn't get it better. Help??
