ACL refers to "anterior cruciate ligament", also known as anterior cruciate ligament. It is one of the most important ligaments in human body, and plays a vital role in sports to prevent knee ligament injury. When anterior cruciate ligament is injured, surgery is often needed to repair it. ACL injury not only affects daily life and sports activities, but also may lead to early degeneration of knee joint if it is not treated in time.

Physical actions such as external force impact, violent rotation, sharp turn and sudden stop can all cause ACL damage, especially collision and torsion on the sports field. In addition, extreme sports such as skydiving and skateboarding are also common causes of ACL injury. In addition to sudden physical impact, ACL may suffer from chronic injury during long-term exercise, such as walking, running or climbing mountains for a long time, which may increase the risk of ACL injury to some extent.

The best way to prevent ACL injury is to arrange physical exercise reasonably and enhance the strength and stability of related ligaments and muscles. This can be achieved through proper training and regular rest. In addition, we must pay attention to safety when exercising, and avoid frequent lateral activities and violent rotation. Once ACL injury occurs, it needs timely diagnosis and treatment. Correct understanding and active treatment of ACL injury is an important measure to curb the influence of this kind of injury, and some simple physical therapy methods such as physical therapy and aerobic exercise can promote its elimination. In some cases, it is necessary to use surgical treatment to repair.
