The number of anterior cruciate ligament (ACL) injuries in adolescents is rising. However, there is very little high-quality evidence to guide decision-making in management of pediatric ACL injuries. In October 2017, the International Olympic Committee hosted an international expert group, and the consensus statement on prevention, diagnosis and management of pediatric ACL injuries was posted. The consensus statement topics about 1) injury prevention and 2) high-quality rehabilitation were reported in this article. In addition, mechanism, risk factors, and effective preventive measures for ACL injuries in adolescent athletes were also reviewed. Stiff landings were associated with increased ACL injury risk for young female athletes, and the ACL injury risk could be reduced by neuromuscular control training program that targeted younger participants with high-compliance. Furthermore, we challenged to elucidate the movements requiring greater trunk accelerations and its frequencies during junior badminton games. ACL injuries in badminton have commonly occurred during single-leg landing after an overhead stroke in the backhand-side court. From our researches, the mediolateral physical demand and high-risk posture in the backhand-side court may be associated with a higher incidence of knee injuries during badminton games.
