title: Pseudoarthrosis between a patellar tendon ossicle and the tibial tuberosity in Osgood-Schlatter's disease.
abstract: We report a case of pseudoarthrosis between a patellar tendon ossicle and the tibial tuberosity. A man, 18 years of age, had persistent symptoms of Osgood-Schlatter's disease from the left knee for 3 years. Conservative treatment was without effect. Excision of the ossicle resulted in complete relief of symptoms. Histologic examination showed a pseudoarthrosis covered with cartilage and no sign of inflammation. Persistent symptoms of Osgood-Schlatter's disease for more than 2 years indicate exploration.
