Meniscal tear: description
The menisci (gr. Mēnískos = moon-shaped body) are two ring-shaped cartilages that lie at the side of the knee between the bones of the upper and lower leg. They act as shock absorbers, that is, they increase the contact surface and reduce the friction between the bones. The menisci thus allow a sliding, painless movement in the knee joint. At least, as long as there are no cracks in the tissue, the so-called meniscal tear.
In particular, the inner and outer meniscus are distinguished in the knee joint. The medial meniscus is crescent-shaped and relatively immobile, because it is firmly attached to the inner ligament (collateral ligament). The result: He can not avoid acting forces so well and therefore tears easier. In contrast, the lateral meniscus has an approximately circular shape and is less fixed to the surrounding tissue. He therefore has a greater range of motion in force, a meniscal tear occurs less often in him.
Typically, a meniscus injury happens especially in rotary-fall injuries (Traumatic)For example, in sports such as skiing or football. But a meniscal tear also occurs at Age-related wear or one chronic overload the knee joint, for example, in some occupational groups with predominantly squatting activity, such as tilers.
A meniscal tear can pull through the tissue in all directions. In addition to the shape of the tear, it is crucial for the choice of therapy at which point the tear in the meniscus is located. A suture is often possible in the well-perfused outer zone, while in the poorly perfused inner zone, the injured meniscal component often has to be removed.
A meniscal tear is relatively common, affecting about 160 out of every 10,000 people. Not every meniscal damage causes acute discomfort or pain. Depending on the size and extent of the tear, various symptoms may occur that impede the affected person differently. The treatment of the meniscal tear depends on this: In cases with no or limited restrictions, a meniscal tear is treated conservatively (without surgery). In severe cases, surgical therapy or an artificial meniscus may be necessary.Knee pain - it's behind itBy injury, different parts of the knee joint can be affected. But other causes can cause pain.
