title: Bifocal osseous avulsion of the patellar tendon from the distal patella and tibial tuberosity in a child.
abstract: This case report describes a 12-year-old boy, who suffered an injury to the right knee in a skateboard accident. Radiographs and surgery confirmed the extremely rare bifocal avulsion fracture including the distal patellar pole and tibial tuberosity. Open reduction and internal fixation was accomplished, and 4-month follow-up demonstrated a good outcome.
