Medial meniscus injury: images of tear to the posterior horn

You have to see a normal image of a meniscus in arthroscopy, to understand how you can see the meniscal tear.

The arthroscopic photograph #1 shows a medial meniscus (MI) and his posterior horn : the cartilage of the femur (F) and tibia (T) are also normal.

Image #2 and 3: this arthroscopic photograph (#2) shows a medial meniscus injury (posterior horn) with a posterior “flap” . In the third image you can see a medial meniscus tear (complex rupture of the posterior horn) .
