ACL injury
The anterior cruciate ligament (ACL) provides stability to the knee joint. It controls the front to back as well as the rotational movement in the knee.
LCL injury
The collateral ligaments are on the sides of your knee. The lateral collateral ligament is found on the outside of the knee, and the medial collateral ligament is on the inside of the knee.
MCL injury
The collateral ligaments are located on the sides of your knee. The lateral collateral ligament is found on the outside of the knee, and the medial collateral ligament is on the inside of the knee.
Multiligament injury
A multiligament knee injury is when two or more of the ligaments of the knee have been injured. These types of injuries are uncommon and require a significant force to occur. Patients are often involved in a high-velocity sporting event or a motor vehicle accident
PCL injury
The posterior cruciate ligament connects the back of the femur bone to the back of the tibia bone. It is the strongest ligament in the knee and the least likely to be injured. It prevents the tibia from slipping backwards on the femur.
Posterolateral corner injury
A posterolateral corner (PLC) injury involves damage to the joint lining, ligaments, and tendons outside of the knee.
