Both support and stabilize the knee. ACL is the anterior cruciate ligament that keeps your shinbone from sliding forward. MCL is the medial collateral ligament that prevents your femur from sliding from side to side. A knee injury can damage either of these ligaments.

What does LCL injury stand for?

An LCL injury is a sprain or tear to the lateral collateral ligament (LCL). The LCL is a band of tissue on the outside of your knee.

What does MCL stand for?

The medial collateral ligament (MCL) is one of the ligaments in the knee joint.

What is an MCL and PCL?

What is an MCL or PCL Injury? The MCL (medial collateral ligament) and PCL (posterior cruciate ligament) are two of the four ligaments (ACL, MCL, PCL, and LCL) that provide stability to the knee as well as prevent the knee from moving too far in a specific direction. The MCL is a ligament on the inside of the knee.

Whats worse ACL or MCL?

While not always the case, an ACL tear is in most cases going to be the more severe injury. It is considered worse than tearing the MCL because ACL tears are in general more complex to treat and require a longer recovery time after surgery.

Does the LCL heal on its own?

No specific exercise can help a LCL heal. The ligament will heal on its own, and the main thing to do is to prevent re-injury to the ligament during its healing.

What is the outside of your knee called?

The outside half (farthest away from the other knee) is called the lateral tibial plateau, and the inside half (closest to the other knee) is called the medial tibial plateau. The patella glides through a special groove formed by the two femoral condyles called the patellofemoral groove. ​

Why is it called the ACL?

Abbreviated ACL. … The anterior cruciate ligaments, one on either side of the knee, are so called because they cross each other in front of the knee. “Cruciate” taken from the Latin “crux” for “cross” means “in the form of a cross.” See: Anterior cruciate injury.

How do you know if LCL is torn?

Symptoms of LCL Injury Your knee may feel like it could give out when you’re walking or standing. Your knee may lock in place or catch when you walk, instead of moving smoothly. You may not have your normal range of motion. Your foot may feel numb or weak, along with your knee pain, if it’s a severe tear.

What are ligaments?

A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.

Article first time published on

Where is ACL and LCL?

Lateral collateral ligament (LCL) runs along the outside of the knee. It prevents the knee from bending out. Anterior cruciate ligament (ACL) is in the middle of the knee. It prevents the shin bone from sliding out in front of the thigh bone.

What is the difference between MCL and LCL?

The MCL tear may be an isolated injury or it may be part of a complex injury to the knee. The final ligament is the LCL or lateral collateral ligament. It connects the femur to the fibula, the smaller bone of the lower leg on the outer side of the knee.

Where is ACL located?

Anterior cruciate ligament (ACL). The ligament, located in the center of the knee, that controls rotation and forward movement of the tibia (shin bone).

What does MCL stand for in laboratory?

4.8. 1.1. 1 Inorganic Arsenic. The maximum contaminant level (MCL) is the highest level of a contaminant that is allowed in drinking water based on cost benefit analysis and is enforceable.

What is the most painful ligament to tear?

Quadruple Knee-Ligament Injury For this reason, the quadruple ligament injury must be one of the most painful football injuries imaginable.

Where does ACL tear hurt?

You will likely feel pain in the center of your knee during an ACL tear. Because the MCL is located on the side of your knee, the pain and swelling will be located on the inside of the knee structure rather than the middle.

Can you walk with a torn ACL or MCL?

Full tears of the ACL and MCL are serious and can affect future movement. If the MCL or ACL tears, the result is usually pain, swelling, stiffness, and instability. In most cases, the injured person can still walk with the torn knee ligament. But the movement will be severely limited, not to mention painful.

What are the 3 knee ligaments?

Posterior cruciate ligament (PCL) – The ligament, located in the center of the knee, that controls backward movement of the tibia (shin bone). Medial collateral ligament (MCL) – The ligament that gives stability to the inner knee. Lateral collateral ligament (LCL) – The ligament that gives stability to the outer knee.

What are knee ligaments called?

Cruciate ligaments: The two cruciate ligaments are inside your knee joint and connect your femur to your tibia. They cross each other to create an X. The anterior cruciate ligament (ACL) is located toward the front of the knee. The posterior cruciate ligament (PCL) is behind the ACL.

How do you treat a collateral ligament injury?

1. Rest and protecting your knee.
2. Ice or a cold pack.
3. Wrapping your knee with an elastic bandage (compression).
4. Propping up (elevating) your knee.
5. Anti-inflammatory medicine.

Do you need surgery for LCL tear?

When the LCL is completely torn or not healing with nonsurgical therapy, you may need surgery to reconstruct the ligament. While some LCL injuries can be treated with anti-inflammatory medications as well as conservative treatments such as rest, ice, compression, and elevation, most people will need surgery.

What happens if you don't get surgery on a torn LCL?

If an LCL tear is left untreated, the knee may become unstable and prone to further injury over time. That’s why it’s so important to visit the doctor as soon as possible, rather than later, before the injury can take a toll on the surrounding tissue systems.

Can you walk with LCL tear?

For a while, you’ll have to use crutches or a knee brace. Your healthcare provider will tell you how long you need to wait before putting weight on your knee. You’ll be back to walking normally after your LCL tear heals.

What is the function of the LCL?

Function. The LCL stabilizes the lateral side of the knee joint, mainly in varus stress and posterolateral rotation of the tibia relative to the femur. The LCL acts as a secondary stabilizer to anterior and posterior tibial translation when the cruciate ligaments are torn.

What is the role of the LCL?

The LCL is a strong connection between the lateral epicondyle of the femur and the head of the fibula, with the function to resist varus stress on the knee and tibial external rotation and thus a stabilizer of the knee. When the knee is flexed to more than 30°, the LCL is loose.

Why is the ACL important?

The purpose of the ACL is to keep the lower leg from sliding in a forward direction (the PCL keeps it from sliding backwards). Most importantly, the ACL aids in the stability of the knee joint, preventing it from shifting during quick side-to-side motion such as shuffling, sidestepping, or cutting.

How does a ligament work?

Ligaments are tough fibrous cords composed of connective tissue that contains both collagen and elastic fibers. The elastic fibers allow the ligaments to stretch to some extent. Ligaments surround joints and bind them together. They help strengthen and stabilize joints, permitting movement only in certain directions.

What is the meaning of ligament injury?

When ligaments are damaged, the knee joint may become unstable. Ligament damage often happens from a sports injury. A torn ligament severely limits knee movement. This results in the inability to pivot, turn, or twist the leg. Surgery is a choice to repair a torn ligament if other medical treatment is not effective.

Where are ligament located?

Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. You have ligaments around your knees, ankles, elbows, shoulders, and other joints.

Where is your ACL MCL and LCL?

Medial collateral ligament or MCL – connects the thigh bone to the shin bone on the inside of the knee—MCL stabilizes the inner knee. Lateral collateral ligament or LCL – connects the thigh bone to the fibula, the smaller bone of the lower leg on the outer side of the knee—LCL stabilizes the outer knee.

What's the difference between an ACL and LCL?

The ACL prevents the tibia from sliding forward along the femur, while the PCL prevents the tibia and femur from sliding towards each other. The other two ligaments of the knee, the medial collateral ligament (MCL) and lateral collateral ligament (LCL).
