Acute tibial tubercle avulsion fractures in the sporting adolescent

摘要

The authors report 7 cases of acute tibial tubercle avulsion fractures. The fracture occurred in 6 out of the 7, after an abrupt tension of the patellar tendon in male sporting adolescents (age 13–17 years). Two patients presented symptoms of homolateral Osgood-Schlatter’s disease before the lesion.
