Summary
Menisci
Menisci are crescent-shaped fibrocartilaginous structures that are triangular in cross-section. The lateral meniscus is more circular and covers 70% of the lateral tibial plateau, and the medial meniscus is C-shaped and covers 50% of the medial tibial plateau.
The menisci are composed primarily of type I collagen. The fibres are arranged radially and longitudinally (circumferential). Longitudinal fibres help to dissipate hoop stresses in the meniscus. The hoop tension is lost when a single radial cut or tear extends to the capsular margin. The extracellular matrix consists of proteoglycans, glycoproteins and elastin.
