Knee MRI femoral cartilage variant

Hi OCADers,

Adult patient with mild OA.

Unusual morphology at the osteochondral layer of medial femoral condyle. I have seen this 1-2 before and interpreted as a variant. Does anyone know more about this? How does it develop (growth disturbance?), frequency, any relevance for developing OA etc. Any literature reference would also be appreciated. Thx.

Best,

Björn

  1. Thank you to all who replied:
    ocadmsk.com/knee-mri-femoral-cartilage-variant/

    Responses were:

    3 x chondral pseudo-defect (similar to patella dorsal defect).
    1 x similar to lateral femoral notch
    1x hereditary variant
    1 x analogous to hip (“stellate lesion”)
    1 x healed OCL in childhood

    Most believe this to be some sort of developmental variant.

    It’s not mentioned here or in any other publication I looked at but this is still good resources. Maybe I will name it myself, the ‘Jobke notch’ 😉.
