fragmented supero-latateral pole of patella with two distinct patellar fragments
Inflammation inside sincondrosis, but no bone marrow edema on the adjacent sides.
Retropatellar cartilage with slight modiffication in signal, and some structurual changes - condromalacia retropatelae grade II
due to the fact that it is a well corticated fragment, it is not a fracture, but a non-fused grows patellar nucleus - the so called "bipartite patella"
-the history is although important
-well corticated fragment
-usual location - supero-lateral pole of the patella
-pain due to inflammation of the sincondrosis between the fragments - due to overuse
