ABSTRACT
Introduction: Tibial tubercle avulsion fractures are a rare lesion in adolescence that occurs during sports such as basketball, soccer, and volleyball. They result from a forceful extension of the knee against a fixed leg. Case Report: Case 1: A 14-year-old adolescent who reportedly experienced severe knee pain when he jumped to head a ball during a soccer game. Case 2: A 17-year-old teenager who reportedly experienced severe knee pain on takeoff during a high jump event. Case 3: A 16-year-old who reportedly felt pain during takeoff to catch a basketball. Case 4: A 14-year-old adolescent who reportedly felt pain in his left knee on takeoff from a high jump during a basketball game. All of these patients presented with a defective leg extension on clinical examination. Radiographs showed an avulsion fracture of the anterior tibial tuberosity and treatment was surgical. Discussion: Avulsion fractures of the tibial tuberosity are rare lesions. They occur in adolescents during sports and are usually accompanied by fracture fragment displacement, indicating reduction, and internal fixation surgery by screwing. In the short term, the result is satisfactory. Conclusion: Tibial tuberosity avulsion fractures when managed in their entirety, give better results with a precocious return to sport.
