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.
