Surely there is not a person in the world who would not have ever experienced a phenomenon like a crunch in the knee area. During squatting, fast walking or just bending limbs. Someone does not pay any attention to this, and someone immediately panics. Both reactions are inadequate. Before seriously worried, you need to understand why the knee crackles. Well, in order to understand this, we must at least pay attention to this symptom. However, it can mean nothing at all.

The physiological crunch and the circumstances of its appearance

Specialists distinguish two types of crunch in the knee joints - physiological and pathological.

If the knees crunch when squats or loads of a different kind occur and this happens rarely, then most likely we are talking about the physiological nature of the phenomenon. Such a crunch is not accompanied by painful sensations, the knee joint looks as usual - a tumor is not observed. A person does not experience any other discomfort, except for a purely psychological one.

For your own comfort, you can, of course, be examined, but if the knee crunches once a year, you should not worry.

Pathological crunch

The pathological crunch of the joint is quite different. It does not occur during active, but during passive movement. When the knee crunches when bent, which is done by the limb, not independently, but with outside help: for example, a person flexes the leg with the help of hands or this is done by the doctor during the examination. Also a symptom can arise when stretching the leg or maximizing the bending of the fingers.

Often a crunch in such cases is accompanied by unpleasant clicks or even creaking. The joint of the knee can be sore, swollen and lose mobility. Sometimes around him blushing skin and increases the overall body temperature. The phenomenon is of a regular nature and requires mandatory medical intervention.

There are many reasons for the pathological and physiological crunch. The most common will be discussed below.

Safe causes of crunching

The most common answer to the question, why the knee crackles, many may seem unexpected. And it sounds like this: "The bubbles just burst!"

The thing is that the knee joint is washed with a certain liquid (synovial). It has a certain composition (molecular, water and gas). The movement of the joint, of course, changes the state of this fluid, namely its temperature and pressure. Dissolved gases begin to bubble and burst. Usually, this happens unnoticed for the owner of the knee joint. But sometimes (with sudden movements, for example) it can be cliched.

It's completely safe and does not talk about any illness. But it is important to remember: the key word here is "sometimes." If the crunch bothers often, it's better to be safe.

Another safe cause of the crunch in the knees is a bone engagement with a ligament or tendon. This occurs in those cases where the bone protrudes slightly, which is an innate phenomenon, and sometimes it is an age-related phenomenon. It is often observed in children and adolescents, the body of which grows and develops rapidly but unevenly.

A crunch in the joints is accompanied by the aging process, when the composition of tissues changes. This is considered the norm.

Some people have a congenital defect, in which the knee joint is equipped with weak ligaments. This provides the person with a magnificent stretch and gives him the chance to become an outstanding acrobat or gymnast. But periodically provokes a crunch.

Inflammatory processes

If the knee crunches when bent (especially passive), it can be a symptom of such formidable inflammatory diseases as arthritis, arthrosis, bursitis, tendenitis, deforming osteoarthritis and others. They can almost completely immobilize a person and permanently make them disabled.

Especially should be alerted to those who have swollen knee, crunches often and thus it hurts. With a visit to the doctor, you can not wait a single day.

Sedentary lifestyle

This reason alone is not terrible. But the consequences of it can be quite serious.

People, leading a sedentary lifestyle, whose work, for example, is connected with sitting at the computer, can often notice that knee crackles when walking.

You can say that nature sends a warning signal: the body grows old, muscles and ligaments atrophy, urgent physical rehabilitation is needed, otherwise there is a risk of turning into a real ruin. And then serious diseases will be piled up.

Strong physical activity

Another explanation why crunches the knee,  excessive physical activity. The situation is well known to athletes who have overdone with exercises, and people who carry weights. Can pass without consequences, and can cause, for example, arthrosis.

Injuries and injuries

With a crunch in the knees, people who have suffered joint injuries in the past often encounter. The latter weaken and crunch from the slightest tension.

The knee joint meniscus is the most affected  it is damaged or torn due to the sharp load, which coincided with the process of its rotation and extension. This often happens with athletes. Trauma to the meniscus is accompanied by pain in the joint, swelling, fever, and also with characteristic clicks.

Damaged joints should be protected, because they are in a weakened state and risk injury again.

Diagnosis of diseases of the knee joint

To know exactly why knee crackles, you should visit a doctor. It can be either an arthrologist or an orthopedist.

The doctor will appoint the necessary examinations, after which the patient will receive an answer to his question.

As a rule, the diagnosis begins with the most simple methods. The doctor conducts a conversation about the presence or absence of knee injuries in the past, examines the joint, examines the nature of clicks. Further, routine blood tests, as well as ultrasound, computed tomography or MRI, are prescribed.

These available means, as a rule, give exhaustive information. And only in extreme cases, when there are grounds for serious suspicion, a doctor can send his patient to a biochemical blood test or an analysis to identify a rheumatoid factor. They are done in order to exclude arthritis, to look at the general condition of the internal organs and to pinpoint the cause of the crunch in the knees.

Because of pathologies, knees crackle. Than to treat?

The treatment of a crunch in the knee entirely depends entirely on what is caused by this phenomenon. If a person has led a practically immobile lifestyle for many years and suddenly decided to go in for sports, he noticed that knees crack with knee bends, his main task is not to stop at what has been achieved. Moderate physical activity, regular exercise will reduce the problem: joints get stronger, and this symptom will pass. Therefore, if knees crunch when squats, then you do not need to give up the sport.

Athletes, "overloaded" knees, will help rest. People suffering from obesity or some kind of illness that indirectly provoke problems with knee joints should fight the root cause of ills: get on a diet, eliminate illnesses ...

If it is a question of such serious diseases as arthritis, arthrosis, etc., then the course of treatment is assumed to be complex and lengthy. It includes the administration of antihistamines, hormonal, anti-inflammatory drugs, magnetotherapy, physiotherapy, as well as external application of ointments with warming components. In some particularly difficult cases, it may be necessary to install an endoprosthesis.

Injuries, in particular a damaged knee joint meniscus, often require surgical intervention. And only if the gap is insignificant, can we do with conservative methods: drugs that remove puffiness and pain, anti-inflammatory drugs, cooling bandages and bandages that fix the joint, and also therapeutic gymnastics.

Traditional medicine also knows a lot of ways to combat problems with knee joints. For example, she suggests swelling and pain with the help of mints, eucalyptus and fir baths. Another remedy is made from the leaves of white cabbage, plantain and chestnut. They need to be taken in equal amounts and turned into a homogeneous gruel, which is applied to the diseased knee in the form of a compress for four to six hours. They say that it helps a lot.

There are many recipes, but any of them must be agreed with the attending physician.

Prevention of crunching in the knees

As you know, any problem is easier to prevent than to solve. This applies to diseases of knee joints, accompanied by a crunch. Treatment can come out expensive, debilitating and, incidentally, non-invasive (after all, one cure - another cripple). But prevention and resources do not take much, and will not do any harm exactly.

What preventive measures are the doctors advised to take?

  • Women are not recommended to wear high-heeled shoes for more than six hours a day.
  • People whose professional activities are associated with a constant sitting in the armchair, it is recommended that they often get up and walk around the office, and in their free time to visit the pool, ride a bicycle or just run around the house.
  • If, on the contrary, work is associated with heavy loads on the knee joints, you should at any opportunity allow them to rest.
  • If there is a risk of joint injury, knee pads should be worn.
  • Good for knee joints such exercises as "scissors" and "bicycle". They develop them and make them more enduring.
  • You can not tolerate hypothermia of the joints - it can trigger inflammation.
  • Any viral infections must be urgently treated - they are capable of provoking arthritis, arthrosis and other insidious ailments.
