What it is
Almost circular (O-shaped) fibrocartilage ring on the lateral tibial plateau.
Function
Distributes load across the lateral compartment and aids knee stability.
Size
≈ 3.5 cm across, 10 mm wide
Clinical note
It is more mobile than the medial meniscus, which partly protects it from tearing.
