I had AVN of both of my hips caused by the prednisone. When the AVN first started I had debilitating hip pain, first in just my left and a few months my right startd in. I had x-rays and MRI's done to diagnose this. When my left one got to the point when I finally needed surgery, which was about
a year after it started, I didn't have anymore pain. My orthopedic surgeon said that was normal for amount of dead bone, but if I didn't have surgery to replace it I risked it breaking completely and would be in more pain than I had before. So, I had my left hip replaced in 2000 but we left the right one alone to see how it progressed. I ended up having the right one replaced in 2002. I was told my replacements would last 20-30 years, depending on my weight on how well I take care of them. Since I was still in my 20's I get to look forward to another surgery, but not for a very long time yet. I won't lie, and certainly don't mean to scare anyone, but the recovery from the surgery was hard; 6 weeks of physical therapy and basically learning how to walk again. I can say, though, that it was definately worth it.
I hope this helps in your decision making. Take tare.
