Dorsal defect of the patella
RH Denham
Of five patients with a dorsal defect of the patella, four were followed
for seven to thirteen years. The lesion causes a persistent change in the
radiographic appearance of the bone and there may be some residual
discomfort in the involved knee. It is best demonstrated on tomograms and
on posterior oblique radiographs of the patella. The cause of the defect is
unknown and its pathology has not been clearly defined.
