Anterior Cruciate Ligament Injuries: Etiology and Prevention

Background: Anterior cruciate ligament (ACL) injuries are prevalent among athletes, particularly those participating in high-impact sports such as soccer and basketball. These injuries often result from both contact and non-contact mechanisms, with non-contact injuries being especially common during activities that require rapid changes in direction, jumping, or landing. The incidence of ACL injuries is notably higher among female athletes compared to their male counterparts, attributed to various factors including anatomical differences, hormonal influences, and neuromuscular control. Understanding the causes of ACL injuries is crucial for developing effective prevention strategies aimed at reducing their occurrence and associated long-term complications. Methods: This study reviews the existing literature on ACL injuries from ۲۰۱۱ to ۲۰۲۴, focusing on the risk factors associated with their occurrence and the effectiveness of various prevention programs. It synthesizes findings from multiple studies that expose anatomical, hormonal, and biomechanical factors contributing to the risk of ACL injury. Furthermore, this study examines the role of environmental factors such as footwear and playing surfaces in influencing injury rates and emphasizes the necessity of comprehensive prevention strategies that include biomechanical training and education for athletes. Results: The analysis reveals that approximately ۷۰% of ACL injuries occur through non-contact mechanisms, often during landing maneuvers. It shows that female athletes are at a significantly higher risk—up to four times more than males—in specific sports. Identified primary risk factors include anatomical changes such as femoral notch width and pelvic alignment, as well as neuromuscular control deficiencies that affect how athletes absorb forces during dynamic movements. Additionally, prevention programs focusing on improving strength, flexibility, and specificity have demonstrated effectiveness in reducing injury rates. However, despite these advancements, many questions remain regarding the optimal implementation of these programs across different athletic populations. Conclusion: The increasing prevalence of ACL injuries among athletes underscores the urgent need for targeted prevention strategies. While current research highlights significant anatomical and hormonal risk factors, further investigation is essential to fully understand the complex interplay of variables influencing these injuries. Effective prevention programs emphasizing neuromuscular training can significantly reduce the incidence of ACL injuries. Nonetheless, ongoing research is necessary to refine these interventions and enhance their application across various sports contexts. Moreover, by addressing both intrinsic and extrinsic risk factors, stakeholders in sports medicine can work towards minimizing the burden of ACL injuries on athletes.
