Football is one of the most popular sports in the world, and given its intensity and demands, lower extremity injuries, particularly knee injuries, are common among young athletes. The knee, as one of the most complex and burdened joints in the body, is at high risk of injury due to dynamic movements, changes in direction, and contact with other players. Knee injuries present a significant problem in sports, especially among young athletes such as adolescent football players, whose physical maturation is still ongoing. Studies have shown that knee injuries account for a significant portion of total sports injuries among football players, particularly in adolescents. The prevalence of knee injuries in young football players varies depending on age, gender, level of play, and frequency of training and matches. Research suggests that adolescent football players have an increased risk of injury due to biomechanical changes in the body during growth and development, including increased height, changes in muscle strength, and coordination. Furthermore, statistics still indicate a slight increase in the number of injuries. The cause can be attributed to the ever-growing range and intensity of training, as well as the increasingly demanding competition schedules. The capacity for training poses certain challenges for adolescents who face high workloads, which can also lead to negative consequences. Maturation status, growth rate, and lower limb growth rate represent risk factors for knee injuries in adolescents. The quantity and severity of injuries could be reduced by raising awareness about injury causes and prevention. However, this has not yet found its place in the education of lower-league athletes, leading to injuries that may result in prolonged absences from the field and the need for surgical intervention.
