What does the tibial collateral ligament?

The tibial collateral ligament is also known as the medial collateral ligament (Video) or MCL. It is a ligament located along the inside of your knee that connects the femur (thighbone) to your tibia (shinbone). The knee relies on ligaments, which connect bone to bone, and surrounding muscles for stability.

Where is the tibial collateral ligament located?

The medial collateral ligament (MCL), or tibial collateral ligament (TCL), is one of the four major ligaments of the knee. It is on the medial (inner) side of the knee joint in humans and other primates. Its primary function is to resist outward turning forces on the knee.

What ligament prevents valgus forces at the knee?

Medial collateral ligament (MCL) – prevents lateral movement of the tibia on the femur when valgus (away from the midline) stress is placed on the knee.

How do you diagnose a medial collateral ligament injury?

The test is performed by flexing the knee into 90 degrees and externally rotating the tibia. This position of the knee causes relaxation of the cruciates while the collateral ligaments are tightened . When pain is felt on the medial side of the knee, an injury to the MCL complex is probable .

What does LCL pain feel like?

Symptoms of LCL Injury If you hurt your LCL, it’s common to have pain and swelling. These symptoms are also common: Your knee may feel stiff, sore, or tender along the outer edge. Your knee may feel like it could give out when you’re walking or standing.

Where does an LCL injury hurt?

Where does a MCL tear hurt?

MCL injuries hurt. Most people feel pain along the inside edge of the knee, and they also have swelling. You might hear a pop when the damage to the knee takes place, and your knee may lurch to the side. You may find it hard to walk, or feel like you can’t put pressure on the leg with the hurt knee.

Which ligament prevents varus force?

the lateral collateral ligament
The main function of the lateral collateral ligament, the LCL, is to resist varus displacement.

Can you bend your knee with a torn MCL?

When your MCL is damaged, your knee can over-extend itself, or bend too far in a direction that it’s not supposed to bend. You may heal on your own with basic care, rest, and rehab. But if your injury is severe, you may need to have surgery.

How long does it take for a medial collateral ligament to heal?

Recovery time for an MCL injury depends on the severity of the damage. On average, these injuries take six weeks to heal. No matter the grade of the tear, initial treatment focuses on immobilizing the knee and reducing pain and inflammation.

Where is the tibial collateral ligament ( MCL ) located?

Tibial Collateral Ligament. The tibial collateral ligament (TCL), also known as the medial collateral ligament (Video) or MCL, is a ligament located along the inside of your knee that connects the femur (thighbone) to your tibia (shinbone).

What is the function of the medial collateral ligament?

The medial collateral ligament (MCL) is a wide, thick band of tissue that runs down the inner part of the knee from the thighbone (femur) to a point on the shinbone (tibia) about 4 to 6 inches from the knee. The MCL’s main function is to prevent the leg from extending too far inward, but it also helps keep the knee stable and allows it to rotate.

How big is the tibial collateral ligament in the femur?

Tibial collateral ligament. The tibial collateral ligament is also called the superficial medial collateral ligament. It is about eight to ten centimeters long and stretches from femur’s medial epicondyle (a bony protrusion at the bottom, inner-side of the bone) to the two attachments on the tibia bone.

When does the medial meniscus and tibial collateral ligament tear?

This has clinical relevance because if the knee suffers an excessive abduction, which is a clipping-type injury, both the medial meniscus and the tibial collateral ligament will tear. As one of the four major ligaments in the knee, such an injury can take numerous months to heal.
