If your leg is the way it is through the boney structure then physio wont be able to change this. They should however be able to help you strengthen around your knee and try to stabilise your knee cap.
There may be muscles that you can work around your hip to try and reduce the effect of your muscles on pulling your knee cap out of alignement.
When you see your physio ask if they feel it is related to the way your hip sits in the joint or whether there may be other factors...such as leg length discrepencies. Sometimes if one leg is longer than the other it can cause the appearence of a hip problem and may be improved with a heel raise.
Write down the questions that you have for your physio..let them assess you and get them, if possible to answer the questions you have, and explain in laymans terms what this means to you and what you can do to help.
Good luck
