Anterior cruciate ligament
The knee ligaments provide stability. They become frequently injured in sports due to rotation, hyperextension, sudden deceleration, or direct trauma. The anterior cruciate ligament (ACL) is one of several types of ligaments. Despite its small size, the ACL plays a crucial role in preventing tibial dislocation.
What is the anterior cruciate ligament (ACL)?
The anterior cruciate ligament of the knee provides over 90% of the stability for the femorotibial joint. It prevents the tibia from moving anteriorly relative to the femur and limiting extreme rotation. Various mechanisms, with sports accidents being a major cause, can lead to the rupture of this ligament.


ACL Characteristics of the anterior cruciate ligament
The lack of braking causes excessive translational movement of the femur and tibia. This instability not only results in pain and a feeling of lack of control for the patient but also hinders their ability to perform many daily activities, work, and sports.
Although it is sometimes possible to treat a rupture by preserving part of the ligament, a partial rupture often progresses to a complete rupture. To restore function, the ligament must be replaced with a new one. There are several options available, which generally yield similar results, though some differences exist depending on the type of patient.
