The meniscus is a C-shaped piece of cartilage that is located in the knee joint. It functions as a shock absorber, protecting the bones in the knee from rubbing against each other during movement. The meniscus also helps to distribute weight and promote stability in the knee joint.

There are two menisci in each knee, one on the inside (medial) and one on the outside (lateral). They are made up of fibrocartilage, which is a type of cartilage that is dense and strong. The menisci are attached to the tibia (shin bone) and move with the knee joint during flexion and extension.

Meniscus tears are a common injury that can occur during activities that involve twisting or pivoting of the knee, such as sports or physical labor. Symptoms of a meniscus tear may include pain, swelling, stiffness, and locking or clicking of the knee joint. Treatment for a meniscus tear may include rest, ice, compression, elevation (RICE), physical therapy, and in some cases, surgery.

Surgery for a meniscus tear may involve either repairing the torn meniscus or removing the damaged portion of the cartilage. Repairing the meniscus is preferred when possible, as it preserves the function of the meniscus and reduces the risk of future knee problems. However, not all tears are able to be repaired, and in these cases, partial or complete removal of the meniscus may be necessary.

Meniscus injuries can also increase the risk of developing osteoarthritis in the knee joint. Osteoarthritis is a degenerative joint disease that can cause pain, stiffness, and limited mobility. While there is no cure for osteoarthritis, there are treatments that can help manage symptoms and improve overall knee function. These may include physical therapy, pain medication, weight management, and in some cases, joint replacement surgery.

Preventing meniscus injuries is important for maintaining long-term knee health. This can be achieved through proper warm-up and cool-down exercises, wearing appropriate footwear, using proper form during physical activity, and avoiding activities that place excessive stress on the knee joint. It is also important to maintain a healthy weight and avoid smoking, as both of these factors can increase the risk of knee problems.

In conclusion, the meniscus is an important structure in the knee joint that helps to provide stability and protect the bones from wear and tear during movement. Meniscus tears are a common injury that can be treated with rest and rehabilitation, or in some cases, surgery. Preventing meniscus injuries is important for maintaining long-term knee health and can be achieved through proper exercise, form, and weight management. If you suspect that you may have a meniscus injury or are experiencing knee pain or stiffness, it is important to consult with a healthcare provider for appropriate diagnosis and treatment.
