The dorsal defect of the patella

  • D. M. Haswell

The dorsal defect of the patella is described and 16 cases are presented. The typical dorsal patellar defect is a round, radiolucent lesion surrounded by a zone of sclerosis located on the superolateral aspect of the dorsal surface of the patella. The location, radiographic appearance and clinical course of the defect are unique, distinguishing it from other lesions of the patella. The authors suggest that the dorsal defect is an anomaly of ossification and of little clinical significance.
