What is the anterior cruciate ligament?
The anterior cruciate ligament (ACL), also known as the anterior cruciate ligament, connects the femur and tibia in the knee joint. The main function is to limit the excessive displacement of the tibia. It works with other structures in the knee joint to maintain The stability of the knee joint enables the human body to perform various complex and difficult lower limb movements. 
What happens after the anterior cruciate ligament breaks?
Anterior cruciate ligament rupture often occurs in various sports, such as basketball, football, volleyball, skiing, and taekwondo. It is a project that is easy to cause damage, and it also occurs in traffic accidents. At the moment of the break, some people can hear a bang and then cannot move. After the injury, the joints tend to be swollen and heavy, and the time is long. However, after rest or cold application, the pain will gradually decrease, but after that, the joints often have a sense of movement and instability, and it is easy to be sprained again. Repeated sprains will greatly increase the secondary damage of the meniscus and articular cartilage, prone to joint interlocking and limited mobility, and the symptoms of joint instability become more and more obvious, which can cause degenerative changes in the joints and eventually lead to osteoarthritis. happened.
During the examination, the anterior stability of the tibia is lost and the mobility is increased. It is easy to make a diagnosis through some characteristic examinations such as the front drawer test, the lachman test and the axial shift test. Some patients may experience meniscus injury and lower limb muscle atrophy due to prolonged exercise or repeated sprains. MRI can clearly reveal the anterior cruciate ligament with no damage and the accuracy of diagnosis is very high.
What if the anterior cruciate ligament is broken?
Because most of the anterior cruciate ligament rupture occurs in young and middle-aged groups such as athletes and sports enthusiasts, it is important to restore joint stability and reduce or delay joint damage. Conservative treatment or simple suture of anterior cruciate ligament rupture has not been proven. With the development of minimally invasive surgery, the early reconstruction of the anterior cruciate ligament technique under arthroscopy is very mature and has become the best means of treating this disease.
