The knee joint is stabilized by four main ligaments. These ligaments are strong, flexible bands of tissue that connect the bones around the knee.
Knee Ligaments Explained
Here is a breakdown of the four primary ligaments found in the knee:
- Medial Collateral Ligament (MCL): Located on the inner side of the knee, the MCL helps stabilize the knee against forces that push it inwards.
- Lateral Collateral Ligament (LCL): Situated on the outer side of the knee, the LCL provides stability against forces that push the knee outwards.
- Anterior Cruciate Ligament (ACL): Located inside the knee joint, the ACL prevents the shin bone (tibia) from sliding forward on the thigh bone (femur).
- Posterior Cruciate Ligament (PCL): Also located inside the knee joint, the PCL prevents the shin bone (tibia) from sliding backward on the thigh bone (femur).
These ligaments are critical for maintaining knee stability, enabling proper movement, and preventing injuries.
Summary Table of Knee Ligaments
| Ligament | Location | Function |
|---|---|---|
| Medial Collateral Ligament (MCL) | Inner side of knee | Stabilizes against inward forces |
| Lateral Collateral Ligament (LCL) | Outer side of knee | Stabilizes against outward forces |
| Anterior Cruciate Ligament (ACL) | Inside the knee | Prevents forward movement of the shin bone on the thigh bone |
| Posterior Cruciate Ligament (PCL) | Inside the knee | Prevents backward movement of the shin bone on the thigh bone |
