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 nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds.
