Curious bilateral knee marrow signal – what do you think??

For those who are interested, here are the 6 comments that I’ve received for this case:

"bone marrow stress response secondary to altered biomechanics"
"stress reaction from knee hyperextension"
"edema related to overuse/small stress fractures.""Low grade inflammatory arthropathy including reactive (?viral, maybe check for prodrome symptoms)"
"some sort of inflammatory arthropathy. Unusual for infarct but it’s a consideration""disuse osteopenia and vit c def. needs to do PT and get vit C and D"

Thanks everyone!

Hi OCADers,

16 year old male non-athlete with inability to straighten knees. No discoid meniscus or other obvious internal derangement. Curious what you think about the marrow signal.

Thank you!
