Reconstruction of the ACL (anterior cruciate ligament) and repair of a torn meniscus are among the most commonly performed arthroscopic surgeries. Within the knee, these structures perform distinct functions. The ACL helps stabilize and support the joint. There are two menisci in the knee.
â¢ LIQUID (noun) The noun LIQUID has 4 senses: 1. a substance that is liquid at room temperature and pressure. 2. the state in which a substance exhibits a characteristic readiness to flow with little or no tendency to disperse and relatively high incompressibility. 3. a substance in the fluid state of matter having no fixed shape but a fixed volume.
A liquid is a fluid. Unlike a solid, the molecules in a liquid have a much greater freedom to move. The forces that bind the molecules together in a solid are only temporary in a liquid, allowing a liquid to flow while a solid remains rigid. A liquid, like a gas, displays the properties of a fluid. A liquid can flow, assume the shape of a container, and, if placed in a sealed container, will distribute applied pressure evenly to every surface in the container. If you place the liquid in a bag, you can squeeze it into any shape you want.
