I would seek help as my 'better' hip started up with pain and it all came from the dyplasia in opposite hip, got that one fixed and now i am currently having 'better' hip fixed too as the years have made it carry me my whole life and it's made it poorly and super sore, and i've not looked back yet. I had in the dyplasia hip a triple pelvic (three breaks and shove across in pelvis) and the femur broke and lengthened 2 inches 2 yrs ago now, been 1 yr since screws and plates came out. This hip moves better than it ever has, although still weak and needs building up it is 100% improvement. The Better hip i've had done 12wks ago is having my femur rotated so still on crutches and rehabbing it. This is still an improvement on pain, just not mobility yet, early days.
I'm in the UK but Hotchickie on here could possibly help with Aus Surgeons and Hospitals for you
