Hi. Welcome To HealthcareMagic
term is used to describe cellular death in bone tissue.It could be osteonecrosis due prednisone
for immune thrombocytopenic purpura
. The unusual complication can occurr after a much shorter course of steroids
of a considerably smaller cumulative dose than in previously reported cases.
Protected weight bearing Crutches or a walker are very useful in alleviating the pain associated with ON. I recommend the MRI
of the Knee and then consultation with Orthopedics to look for the extent of damage to the knee.
You need to tapper the prednisone. DO not stop abruptly.
