Arthritis itself does not directly cause a meniscus tear, but it can contribute to conditions that increase the risk of such injuries. For example, osteoarthritis can lead to joint degeneration and weakening of the cartilage, making the meniscus more susceptible to tears during normal activities. Additionally, inflammation and pain from arthritis may alter movement patterns, potentially putting extra stress on the meniscus. Therefore, while arthritis may not be the direct cause, it can create an environment that fosters meniscus tears.
The medial meniscus is more likely to be injured than the lateral meniscus due to its attachment to the medial collateral ligament (MCL), which restricts its mobility and makes it more susceptible to injury during twisting motions of the knee. Additionally, the medial meniscus has a C-shape that makes it more prone to tears, especially during activities that involve rapid changes in direction or weight-bearing. The lateral meniscus, being more mobile and less tethered to surrounding structures, often sustains fewer injuries.
Meniscus tears can vary in size, and as such, the symptoms will change with this. Smaller tears will lead to little pain at the time of the injury, while much larger tears would cause much more pain, and lead to a swelling, which can either be immediate or develop over 2 to 3 days.
A torn meniscus is unlikely to heal on its own because the blood supply to this cartilage is limited. In some cases, small tears may improve with rest and physical therapy, but more severe tears often require surgery to repair or remove the damaged tissue. It’s always best to consult with a healthcare professional for an accurate diagnosis and appropriate treatment plan.
As the diameter of the container decreases, the meniscus becomes more pronounced. The meniscus may be convex (curving upward) or concave (curving downward). Most of the time you will find that the meniscus is concave. The most notable exception is the meniscus that forms from mercury. When taking measurement readings it is important that the reading is done properly. The following rules must be adhered to: I. Read the meniscus at eye level. Do not read the meniscus from above or below eye level. Significant measurement errors may occur II. Read the bottom of a concave meniscus and the top of a convex meniscus.

A graduated cylinder or a buret must be read at the meniscus, which is the curved surface of a liquid in a container. Reading at the bottom of the meniscus helps to minimize parallax error and ensures a more accurate measurement.
The meniscus will be more obvious in a cylinder filled with oil. This is because oil has a higher viscosity and surface tension compared to alcohol, leading to a larger curvature at the liquid-air interface of the meniscus.
