Abstract： With the popularity of sports,the number of anterior cruciate ligament(ACL)injuries in children is increasing year by year.Most ACL injuries in children are tibial avulsion fractures or ACL body tears,seriously affecting the health and sports level of the patients.Due to the special anatomical structure of the patients,unclosed epiphysis makes the diagnosis and treatment of ACL injuries more complex.It is necessary to choose the optimal treatment regimen according to the bone maturity and the type and degree of ACL injuries to reduce the damage to the epiphysis and avoid the impact on the growth and development of the patients.It was treated with non-surgical treatment and then ACL reconstruction when the bones were mature in the past,which could cause secondary meniscus and cartilage damage.In recent years,non-surgical treatment has mainly been indicated for children with low-degree ACL injuries and small demand for exercise.With the increased ratio of early surgical treatment,the patients'levels of recovery and return to sports after injury have been improved.However,improper surgery may still lead to complications such as growth and development disorders and postoperative re-injuries.Different from traditional ACL reconstruction,personalized diagnosis and treatment regimen of ACL injuries are very important for the patients at different stages of growth and development.For a better understanding of the diagnosis and treatment of ACL injuries in children,the authors reviewed the research progress on the diagnosis and treatment of ACL injuries in children from the aspects of the characteristics,diagnosis and evaluation,treatment methods,etc.,hoping to provide a reference for the personalized diagnosis and treatment.
