MRI
No joint effusion. The cruciate and collateral ligaments are normal. No evidence of a meniscal tear was identified.
There is evidence of an infarction of the distal femur consistent with the underlying diagnosis of sickle cell disease. There is also evidence that osteochondritis dissecans of the medial femoral condyle is likely to be responsible for current symptoms. No detached intra-articular fragment was identified. There were no other significant findings.
The significant abnormality relates to the appearance of the medial femoral condyle, consistent with osteochondritis dissecans.
