Reason: eval for fx, malalignment History: s/p R patellar dislocation Note is made of a NOF within the distal femoral metaphysis. No evidence of patella alta. There is a small joint effusion. Linear ossific density along the posterior aspect of the knee only seen on the lateral projection is suspicious for an avulsion fracture, although no donor site is evident. Further evaluation with MRI could be considered if clinically warranted. Soft tissue swelling limits evaluation of the extensor mechanism.
Probable avulsion fracture along the posterior aspect of the distal femur and small joint effusion as described above.
