The meniscus cartilage or 'semi-lunar' cartilage is nowadays called the 'meniscus', although the term is sometimes still used when wanting to differentiate meniscus cartilage from articular cartilage.
The meniscus is the mobile shock absorber between the thighbone and shinbone of the knee, while the articular cartilage is the white shiny 'gristle' at the ends of the bones.
The term 'knee cartilage(s)' (implying meniscus cartilage/s) is in common use amongst sportsmen but in fact doctors never use the term amongst themselves and always talk of 'the meniscus'.
