meniscus
- n (anatomy) a disk of cartilage that serves as a cushion between the ends of bones that meet at a joint
- n (optics) a lens that is concave on one side and convex on the other
- n (physics) the curved upper surface of a nonturbulent liquid in a vertical tube
- The cyst came out with the meniscus.
- But I have torn the meniscus in my knee in two places, which requires surgery.
- With Liston facing surgery for a torn meniscus, or cartilage, and out of action for at least six months, the title fight was postponed indefinitely.
