B) Bacterial infection in the knee following total knee replacement
C) Synovial inflammation with painful swelling and warm to touch
D) Bone marrow ischemia due to radiation therapy for cancer
Ans: D
Feedback:
Osteonecrosis refers to necrosis or death of bone and marrow in the absence of infection. All forms of bone necrosis result from ischemia; one of the most common causes is associated with administration of corticosteroids. The site of the lesion is related to ischemia of the vessels involved, rather than a bone fracture or joint area inflammation.
