It depends on the stage of osteonecrosis. If there is destruction bone visible on x-ray, there may be few options other than analgesics and possible joint replacement. If there is no evidence on bony collapse on plain x-ray but changes seen only on MRI scan, you may be a candidate for core decompression in which surgeons remove a section of bone. If you do not have a lot of bony changes on x-ray, now that you are off prednisone, the osteonecrosis may heal.
