title: Tuberculosis of the patella.
abstract: The case of an 8-year-old boy with tuberculous arthritis of the right knee in whom patellar disease was the only radiological abnormality is presented. The patellar findings were a large lytic area with sclerotic borders containing a dense image corresponding to a sequestrum. Open biopsy was necessary for diagnosis, since the radiological abnormalities are consistent with other chronic infectious diseases.
