A concave meniscus occurs when the attraction between the particles of the liquid and the container is more than half the attraction of the particles of the liquid to each other , causing the liquid to climb the walls of the container (see Surface tension § Causes). This occurs between water and glass.
Knee effusion, informally known as water on the knee, occurs when excess synovial fluid accumulates in or around the knee joint. It has many common causes, including arthritis , injury to the ligaments or meniscus , or fluid collecting in the bursa , a condition known as prepatellar bursitis .
Capillary condensation bridges two surfaces together, with the formation of a meniscus, as is stated above. In the case of atomic-force microscopy (AFM) a capillary bridge of water can form between the tip and the surface, especially in cases of a hydrophilic surface in a humid environment when the AFM is operated in contact mode.
Cohesion, along with adhesion (attraction between unlike molecules), helps explain phenomena such as meniscus, surface tension and capillary action. Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces.
Meniscus may refer to: Meniscus (anatomy) , crescent-shaped fibrocartilaginous structure that partly divides a joint cavity Meniscus (liquid) , a curve in the upper surface of liquid contained in an object
Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space without the assistance of external forces like gravity.

If the tear causes continued pain, swelling, or knee dysfunction, then the tear can be removed or repaired surgically. The unhappy triad is a set of commonly co-occurring knee injuries which includes injury to the medial meniscus.
