The main function of the knee collateral ligaments is to control side-to-side motion of the knee and brace it against unusual movement.
Understanding Knee Collateral Ligaments
Knee collateral ligaments are essential for knee stability. They are located on either side of the knee joint and prevent excessive sideways movement. The reference material highlights two key collateral ligaments:
- Medial Collateral Ligament (MCL): Located on the inside of the knee, connecting the femur (thigh bone) to the tibia (shin bone).
- Lateral Collateral Ligament (LCL): Located on the outside of the knee.
Function of Collateral Ligaments: A Breakdown
To further explain the function, here's a table summarizing the roles of each ligament:
| Ligament | Location | Primary Function |
|---|---|---|
| Medial Collateral Ligament (MCL) | Inside of Knee | Resists forces that push the knee inward (valgus stress) |
| Lateral Collateral Ligament (LCL) | Outside of Knee | Resists forces that push the knee outward (varus stress) |
Importance of Collateral Ligaments
Without healthy collateral ligaments, the knee would be unstable and prone to injury during activities like walking, running, and pivoting. They ensure the knee joint remains aligned and functions correctly under stress.
