The cruciate ligament of the knee is located within the knee joint and has an anterior cruciate ligament and a posterior cruciate ligament, which are important ligamentous tissues for maintaining the stability and movement of the knee joint.
The upper end of the ACL begins at the medial aspect of the lateral femoral condyle and ends at the anterior aspect of the intercondylar augmentation of the tibia, the anterior horn of the medial and lateral meniscus. The anterior cruciate ligament connects and stabilizes the femur and tibia, prevents excessive anterior displacement of the tibia, and stabilizes the knee joint, participating in knee extension and flexion.
The superior end of the posterior cruciate ligament begins at the lateral surface of the medial femoral condyle, and the distal end ends at the posterior aspect of the intercondylar elevation of the tibia and the posterior horn of the lateral meniscus. It prevents excessive posterior displacement of the tibia and stabilizes the knee.
Cruciate knee ligament injury is a common ligament injury in sports trauma of the knee, so daily exercise should pay attention to protection, and when discomfort occurs, it is necessary to actively diagnose and treat.
