Case contributed by Dr Kamil Bekalarek

Presentation

Knee injury.

Patient Data

Age: 40 years
Gender: Male

A horizontal tear of the medial meniscal body with an extension to the tibial articular surface well seen on coronal and axial planes. Blunting of the free edge of the meniscal body with flat displaced into inferior (tibial) recess best seen on the coronal plane.

Small subchondral edema of the medial tibial condyle directly under meniscal injury.

Case Discussion

Horizontal medial meniscus tear with flap formation into the inferior recess of the meniscal body.

In meniscal flap formation, it is often difficult to assess tear plane. In the existence of inferior or superior meniscal flap, the horizontal plane is dominant. A displaced meniscal fragment always means unstable tear. Identification of inferior recess flap is particularly important to guide surgeons at arthroscopy.
