What are the Causes and Symptoms of Meniscus Tear?

Meniscus Tear Causes

The part that rests in the middle of the shin bone or tibia and thigh bone or femur is known as the meniscus. There are two menisci located in the knee. These are made up of tough substances known as the cartilage, and develop to conform against the shape and surface of the bone.

It maintains a C-shape that helps restore the overall stability of the joint. It can help prevent the femur surface from sliding off. The meniscus that can be found on the side of the knee is known as the lateral meniscus, while the one located inside of the knee is known as the medial meniscus. The function of this part is to provide resistance for the overall body weight. The meniscus works by helping the bones in the lower legs bear the upper body weight by distributing it evenly. A malfunction of the meniscus could lead to conditions such as arthritis, even at a young age. Since the meniscus is largely avascular, any form of damage will not lead to its repair. Blood vessels are essential in healing because the blood contains cells and substances which can help promote repair. Once a meniscal tear occurs, the damage may be permanent.

Meniscus Tear Symptoms

Because the knee is essential in any activity that requires standing and walking, symptoms of a meniscus tear usually limit these activities. The meniscus allows the gliding of the adjoined bones without much friction. Tearing may be due to either degenerative process or a traumatic injury. A degenerative process occurs throughout aging, while a traumatic injury is usually experienced by athletes involved in field sports such as football. People who experience meniscus tear usually complain of intense pain or swelling. Joint locking or complete inability to stretch the joint is also commonly reported. The most commonly reported symptoms of a meniscus tear include:

• Popping or clicking sound upon movement. The knee may feel week and eventually lock.
• Swelling of the knee. This can develop hours after the injury.
• Knee pain
• Tenderness upon palpation.
• Limited motion of the knee joint. The knee is reported to be stuck, and the patient reports inability to straighten the legs.

Meniscus Tear Treatment

Not all treatments for tears of this extent require surgery. Some may require simple intervention such as first aid treatment. This includes rice therapy. Rest, Ice, Compression, and Elevation may help in the reduction of swelling.
