The four major ligaments in the knee are:
- Anterior cruciate ligament (ACL): Located in the center of the knee, the ACL controls rotation and forward movement of the shinbone (tibia) relative to the thighbone (femur).
- Posterior cruciate ligament (PCL): Found at the back of the knee, the PCL prevents the shinbone from sliding backward.
- Medial collateral ligament (MCL): This ligament provides stability to the inner side of the knee, preventing it from moving too far inward.
- Lateral collateral ligament (LCL): On the outer side of the knee, the LCL helps to prevent the knee from moving too far outward.
These ligaments work together to provide stability and control the movement of the knee joint. Injuries to these ligaments are common, especially in athletes, and can range from mild sprains to complete tears.
