Abstract:
Two cases of osteochondrosis of the superior pole of the patella are reported with histologic findings. Both patients were young girls; one had mild cerebral palsy. Sixteen cases of this disorder have been documented but without histologic study. The histologic features of these two cases showed osteonecrosis with reparative changes. These findings support that this entity is similar to other osteochondroses of the quadriceps mechanism: Osgood-Schlatter disease and Sinding-Larsen-Johansson disease.
