Has anyone had an operation to even the length of their legs?

My AVM and embolizations are destroying my body and because my butt and hip is so large now my leg is significantly longer than the other and it’s causing trouble for me when I try to walk and wreaking havoc on my back, knees, and hips. My radiologist said I will have to see an orthopedic surgeon to fix my legs. If anyone has had this done, what can I expect. You would think I would be used to painful surgeries and long recoveries by now, but I’m definitely not, and I’m still scared.
