74 year old with knee pain. Knee MRI showed serpiginous foci of abnormal
signal in distal femur new from 2 years ago.
Femur MRI shows more extensive abnormal signal in intramedullary bone
extending from the tip of the femoral component placed 5 months ago. Is
this related to reaming the femur for the femoral component. Is it
pathologic or a normal postoperative finding?
Consensus was this is a normal postop appearance: marrow liquefaction from
reaming the femur . No one was sure whether it could be symptomatic.
