subchondral cystic I am going to have surgery on my knee. In the report was abnormal"subchondral cystic" and bone marrow edema. Any info would be helpfull. Bone marrow sounds serious.
I think that your surgeons want you to think that this is way too serious. After all, if they cannot persuade you to have surgery, paying for their Escalades, could become problematic. And why did you have this test (Xray, CT, MRI ?) in the first place?
You need to have a discussion with them about what exactly are your risks if the operation is not performed.
Below is some info from a very high return of a Google search, subchondral bone cyst
a usually cavitary lesion of bone. Various types of bone cysts may be identified: simple or unicameral, epidermoid, aneurysmal, subchondral and ganglion. One type, subchondral bone cysts, may result from pressure or stress on articular cartilage and subchondral bone, leading to synovial fluid intrusion or bone contusion. Bone cysts frequently occur in association with joint space loss and bone eburnation; communication with the joint cavity may or may not be present.
Bone cysts may occur after trauma and in osteoarthritis, rheumatoid arthritis, neurofibromatosis and calcium pyrophosphate dihydrate crystal deposition disease.
Subchondral bone cysts
are a prominant feature of osteoarthritis. Occasionally such cysts form as a sequela of bone injury. Radiographically the lesions are multiple and radiolucent, with a surrounding sclerotic margin. Joint-space narrowing and bone sclerosis are accompanying features.
