What is the cruciate ligerment?

The cruciate ligaments are two key ligaments in the knee joint, known as the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL). They cross each other in the center of the knee, forming an "X" shape, which helps stabilize the joint during movement. The ACL primarily prevents the tibia from sliding forward relative to the femur, while the PCL prevents the tibia from sliding backward. Together, they play a crucial role in maintaining knee stability and facilitating proper joint function.
