Just wanted to make a quick repy to you. My daughter took pred for 4 months (highest tapered dose 90 mg) and now has osteonecrosis (aka avascular necrois) in 9 joints. Hers started as knee pain...her knees would click when she stood and sat down...long story short, the best thing to do is go armed with a your history of Pred use and request an MRI of any joint that is especially bothersome (it will not show up on xray in the early stages). Better safe than sorry...and if you find it early, you may be a good candidate for joint sparing core decompressions (which my daughter has had in all 9 joints). Let me know if I can help any further.
