avulsion fracture of the tibial tuberosity in adolescents: a rare case and surgical fixation technique

Background: only 3% of all proximal tibial fractures result in an avulsion fracture of the tibial tuberosity. it is often seen in youngsters between the ages of 3 and 6 and is less frequent after puberty.case report: a 15-year-old boy was presented with severe left knee pain following a high jump. x-ray and computed tomography (ct) scan showed a tibial tuberosity fracture with joint surface involvement. the damaged part was fixed with a 4.5mm cannulated screw and washer, reinforced with 2 swivelock anchors. in the sixth week, full weight bearing and full range of motion (rom) were obtained.conclusion: the primary objective in managing tibial tubercle fractures is the restoration of both the extensor mechanism and the integrity of the joint surface in cases where they have been compromised.
