called meniscus cartilage layer in the knee joint, responsible for shock absorption and stabilization of the patella during walking and running.In addition, they significantly reduce the friction discs of cartilage.Breaks and damage to the menisci - the most common knee injury.

Types meniscus

Total in humans are two types of menisci: the medial meniscus (inside) and lateral (outside), which are connected in front of the transverse ligament of the joint.The most moving lateral meniscus is considered, his injuries rarely occur.The medial meniscus is associated with the lateral ligament of the knee joint and within less mobile.For this reason, fractures of the medial meniscus is often caused by damage of the ligament.


injury According to statistics, among the athlete

s who received the knee injury, over 60% of people have a damaged meniscus.Of these, 4% - from both meniscus injury, 20% - diseases lateral meniscus 75% - with the medial meniscus damage.Most often, these important parts of the knee are injured not only professional athletes, but also in individuals of 18-20 years actively engaged in physical labor.Children up to 14 years because of the physiological characteristics of the gap and meniscus damage occurs very rarely.The representatives of the stronger sex like illnesses are more common than in women.It is believed that the medial meniscus is less susceptible to damage.

reasons meniscus tear

main cause of meniscus tear is considered to be combined or indirect injury that is accompanied by a rotation of the lower leg inward or outward.Break and meniscus damage happens when a strong and sudden extension of the bent knee position, bringing the abduction and the tibia, much less - by direct injury (striking the ball, hitting the edge of the step or floor).

Repeated direct injuries can lead to meniskopatii and tear.Degenerative changes in the menisci may be the result of chronic microtrauma, rheumatism, chronic intoxication, gout.When combined injury along with rupture of the meniscus commonly observed symptoms such as damage to the ligaments, capsule, body fat and the other internal components of the joint.

Types of ruptures and meniscal damage

Doctors identify several types of meniscal injuries:

  • tears of the meniscus, anterior and posterior horns in transkhondralnoy area;
  • gap parakapsulyarnoy meniscus in the region;
  • cystic degeneration of the menisci;
  • excessive mobility of the menisci at break mezhmeniskovyh ligaments or degeneration;
  • chronic meniscus trauma;
  • all possible combinations of these injuries.

Depending on the nature of the injury meniscus tears are partial and incomplete, transverse and longitudinal, fragmented, and a basket handle, displaced and without bias.Most damaged body itself meniscus injury unit back or anterior horn are less frequent.

meniscus rupture Symptoms

damaged meniscus symptoms:

  • occurrence of difficulties in going up and down stairs;
  • the presence of excess fluid in the joint;
  • impossibility of exercising;
  • atrophy or partial reduction in muscle tissue damaged limb;
  • presence "click" in his knee;
  • increased sensitivity to temperature changes in the knee, which tells about the damage of the internal meniscus.

If the meniscus symptoms indicate the presence of trauma, orthopedic for an accurate diagnosis is to conduct special investigations, including MRI and arthroscopy.The characteristic symptoms are disorders of the meniscus of the joint motion, tissue swelling and increasing pain in extension.

Treatment of meniscus of the knee injury

Treatment depends on its nature and severity of symptoms.The meniscus, characterized by degenerative changes are treated by conservative means.With small breaks the treatment of knee joint meniscus and performed using classical regimens.If there is a large gap painful held arthroscopic surgery on the meniscus.It is worth noting that most of the injuries usually start to treat drugs.And only if necessary after a period of time for the healing of the patient's condition does not improve, carried out an operation.

goal of treatment of the meniscus of the knee joint by surgery is to maximize the preservation of the body of the meniscus.Some lesions can be used during surgery on the meniscus surgical suture, whereby the meniscus can be restored.However, discontinuities with displacement, bundles and complex lesions appoint meniscectomy - surgery on the meniscus removing torn pieces.In modern hospitals such operations are carried out not more than 2 hours, after which the patient needs temporary rest and rehabilitation.
