Tibial spine fractures (TSFs) are avulsion fractures at the site where the anterior cruciate ligament inserts onto the tibial eminence. TSFs typically affect children and adolescents aged 8-14 years. The incidence of these fractures has been reported to be approximately 3 per 100,000 per year, but the rising involvement of paediatric patients in sporting activities is increasing the number of these injuries. TSFs are historically classified on plain radiographs according to the Meyers and Mckeever classification system, which was introduced in 1959, but the renewed interest in these fractures and the increasing use of magnetic resonance imaging led to the recent development of a new classification system. A reliable grading protocol for these lesions is paramount to guide orthopedic surgeons in determining the correct treatment for young patients and athletes. TSFs can be addressed conservatively in the case of nondisplaced or reduced fractures or surgically in the case of displaced fractures. Different surgical approaches and, specifically, arthroscopic techniques have been described in recent years to ensure stable fixation while limiting the risk of complications. The most common complications associated with TSF are arthrofibrosis, residual laxity, fracture nonunion or malunion, and tibial physis growth arrest. We speculate that advances in diagnostic imaging and classifications, combined with greater knowledge of treatment options, outcomes, and surgical techniques, will likely reduce the occurrence of these complications in paediatric and adolescent patients and athletes, allowing them a timely return to sports and everyday activities.
