Two Cases of Inferior Dislocation of the Patella with Impaction into the Femoral Trochlea of Osteophytes on the Superior Pole of the Patella

<table>(a) Plain lateral radiography: the patella is dislocated inferiorly. (b) MRI: the osteophyte on the superior pole of the patella has become impacted in the femoral trochlea. (c) Plain radiography after manual reduction: the osteophyte on the superior pole of the patella is completely fractured (arrow).</table>
