Posterior Horn Medial Meniscus Tear

The Meniscus is important for transmitting load across the Knee.

The Menisci increases the surface area of contact and fills the gaps between differently shaped articulating surfaces.

The Medial Meniscus is more C-shaped, while the Lateral Meniscus is more O-shaped.

Function of Meniscus:

It lies within the Knee Joint and is about 4 cm long, binding the Tibia to the Femur. The ACL prevents forward slipping of the Tibia on the Femur and stops hyperextension of the Knee.

The ACL runs through a special notch in the Femur called the Intercondylar notch and attaches to a special area of the Tibia called the Tibial Spine.
