View left in 3D View right in 3D

What it is

C-shaped wedge of fibrocartilage on the medial tibial plateau, firmly attached to the joint capsule and medial collateral ligament.

Function

Deepens the tibial socket, spreads load and stabilises the knee.

Size

≈ 4.5 cm long, 9–10 mm wide

Clinical note

Tears more often than the lateral meniscus because it is less mobile (part of the "unhappy triad").
