I don't mean to poo poo the PT, but since Pritchett got "intimate" with your hip, I'd rely on his answer. Misalignment may be in reference to misalignemnt of your pelvis in relationship to you back. We should all expect to be "crooked" for awhile after surgery since the hip is swollen, tendor, and you have a limp, and when sitting down, we favor the un-operated side. When I look in the mirror, I'm totally crooked, but at 2 weeks who wouldn't be? Even 4 or 6 weeks.
You should call Susan or Roman and see if you can get a copy or your 2-week x-ray, if you don't have it. Keep in mind it's only a 2D image and it's basically impossible to measure anteversion angle, but you can certainly measure abduction angle and that might give your more confidence, along with Pritchett's advice, that there is no "misalignment of the pelvis with relationship to your femor. The crookedness with your back and pelvis should even out as you recover, 2 or months from now.
