RADIOLOGIC STUDY OF PATELLAR HEIGHT IN OSGOOD-SCHLATTER DISEASE

There are contradictory reports regarding patellar position in the Osg ood-Schlatter disease. We present a prospective statistical study of 1 7 patients with Osgood-Schlatter disease and 12 adolescents without an terior knee pain. The Caton-Deschamps index was assessed on strictly t he lateral radiograph of the knee. The findings indicate a strong asso ciation between Osgood-Schlatter disease and patella alta. This increa se in patellar height would require an increase in the force needed fr om the quadriceps to achieve full extension. This mechanism could be r esponsible for the apophyseal lesion.
