Doctors call joint sound crepitus, which is said to be very common in many people, especially when they are elderly. In the following, we are going to get acquainted with the causes of cryptitis or the sound of cracking in the knee, and also tell you which of the causes of knee crepitus are the worrying factors and you should take action to eliminate them.


The sound of a knee fracture or Crepitus of the knee joint

Crepitus is a knocking sound in the knee. Sometimes people describe this sound as a crushing of the knee joint. We have to say that these sounds are normal in most cases and we should not worry about them, meaning that most of the time the sound of a broken knee joint is not worrying, but you may hear different sounds from all joints of the body, including your knee, during the day. For example, many people liken sounds to the sound of two objects rubbing against each other. In the following, we want to talk more about the sound of the knee joint breaking.


Why is the Crepitus sound of the knee or the sound of the knee drying?

It is said that there are gas bubbles around the knee joint, and in fact the gas around the knee joint causes tiny bubbles to form in the joint fluid or synovial fluid of the knee when a person changes position and moves his knee, for example when the knee Bends and straightens Many of these bubbles that are inside the knee joint fluid burst and the sound of these bursts can be heard in the form of knocking.

So when a person has this knocking sound or a sound similar to crushing in their knee joint when moving and bending their knee, if there is no other sign with the sound, such as swelling and sagging of the knee, locking of the knee and severe pain, do not worry. In cases where this sound is not accompanied by other symptoms, there is no need for medical follow-up

However, if the Crepitus knocking and breaking of the knee are accompanied by the above symptoms, you must see a doctor for examination.

In this part, we want to say what is the reason that we hear the sound of knocking or the sound of crushing and abrasion when moving the knee.


  • Movement of ligaments and tendons relative to each other at the knee joint

To move two bones together, the tendons and ligaments that hold the two bones together must change direction and lengthen and shorten, but by changing the position of these important components of the knee joint, the bones that make up the joint can easily Move together. So every time we open and close our knee, these tendons and ligaments may move back and forth and around. This means that the ligaments and tendons may move in such a way that they create noise in the joint by causing wear on the joint and bone surfaces.

If the cause of the knee-related sounds is the sound of knocking and knee joint corrosion, we should consider the sound to be natural and not disturbing, and be sure that these sounds will not cause a problem for the affected person. It also happens a lot that a person Whoever hears the sounds when the knee moves is worried. We must say that if these sounds are not accompanied by pain, swelling, locking, emptying of the legs and knees, you should not worry.


  • Exit of bubbles and gases from the joint

One of the important causes that we briefly mentioned in the previous section is the outflow of gas bubbles and the bursting of gas bubbles in the knee joint. To make it easier for the joint surface to move together, a slippery fluid called joint fluid or synovial fluid is placed in the joints of our body.


In fact, it is this fluid that makes the joint surfaces slippery and facilitates the movement of the joint and the joint surfaces relative to each other.

All joint fluid in all joints of our body contains dissolved gases. When the joint is moved, the space inside the joint increases. The volume inside the joint increases so that the two joint surfaces can be separated from each other by reducing the pressure inside the joint due to Increasing the volume inside the joint space, The gases dissolved in the joint fluid may change from a dissolved state to a gas and bubble state when these bubbles form and we bend and straighten the joint ,The bursting of the bubbles in the form of the sound of a broken knee may be heard.


In what cases is the sound of the knee joint worrying and serious?

In the previous section, we said that there are two benign and non-serious reasons to justify the sound of knee joint fracture. But in the folowing we want to say which cause of knee joint noise should be taken seriously and when we encounter it, we must see a doctor.

  • Osteoarthritis of the knee

Knee osteoarthritis commonly referred to as knee Abrasion, is one of the most common diseases of the human musculoskeletal system, affecting millions of people each year following aging, increased pressure on the knee joint, and cartilage destruction, The knee occurs between two articular surfaces. With age, the health of the knee cartilage joint will disappear. This reduces the distance between the two joint surfaces and increases the likelihood that the bone surfaces adjacent to the knee joint will rub against each other.


Doctors believe that osteoarthritis and Abrasion and tear of the knee joint is a progressive disorder and is caused by the wear and tear of cartilage and its destruction over time. Cartilage is a slippery tissue that forms the ends of bones and due to its slippery nature causes bone movements Facilitate adjacent joints

As the cartilage degenerates, the surrounding bones gradually become involved. Inflammation of the surrounding soft tissues also occurs. The cartilage of the human body is tissue without blood vessels and nerves. Because there is not enough blood supply to the cartilage, it is said that the cartilage will not heal on its own.

On the other hand, since cartilage is a tissue without nerve fibers, if it is damaged, it does not cause pain, so in the early stages, when the process of cartilage destruction has begun and the person is completely asymptomatic, unfortunately Injuries to surrounding tissues and bone involvement around the joint surface cause the patient to notice pain

Osteoarthritis is a very common disorder and is seen in most people over the age of 65. We must say that not all people with osteoarthritis become symptomatic and among symptomatic people the type and severity of symptoms will not be the same in all people.

We must say that the most common and also the most debilitating arthritis in humans is knee arthritis.

Knee Crepitus is one of the most common and main signs and symptoms in osteoarthritis of the knee.

The most common symptoms of osteoarthritis are knee pain, which usually occurs when the knee is moved. Knee pain in these people increases at night and is generally relieved by resting and decreases in severity.


  • The next symptom is knee dryness

Usually knee dryness occurs after the knee has rested for a while and will improve with moving the knee.

Swelling of the knee is caused by fluid buildup

Enlargement of the knee joint following the formation of bony appendages as well as Crepitus of the knee.

Other less common symptoms include weakness of the muscles around the knee, as well as limited range of motion of the knee and sagging of the knee.

Crepitus is most commonly heard in people with arthritis of the joints, but because the knee joint is more commonly used, this is why it is more common to hear the sound of a crushing knee.

The next cause of ringing in the knee and the sound of breaking from the knee is followed by trauma to the knee, which may be followed by injuries and trauma to the knee and damage to the organs and tissues around the knee, such as meniscus tears. Athletes are more likely to suffer from this series of injuries.


One of the reasons Crepitus occurs when the knee joint moves is a meniscus tear.


  • The third factor is patellar chondromalacia or softness of the patellar cartilage of the knee

Excessive use and overuse of the knee joint or damage to the knee can cause damage, and if the patellar cartilage of the knee is damaged, it can cause conditions similar to softening and erosion of the knee cartilage.

The damage is done to the cartilage that covers the underside of the patella. If you have this disorder, it is normal to have a ghost-like sound from your knee and the so-called Crepitus of the knee.

Rheumatoid arthritis is another cause that can cause Crepitus or a sound similar to a knee fracture. Rheumatoid arthritis is a chronic autoimmune disorder that means that an infected person's immune system mistakenly attacks its own cells, causing inflammation and damage.

In rheumatoid arthritis, the immune system attacks many components of connective tissue, including the joints, and in these people, the sound of the knee, the sound of knocking and the sound of the knee breaking may be heard, so following the destruction of the knee joint in this autoimmune disease, It can cause knee pain.

Another important point is that joint damage is also seen in many other autoimmune disorders


How can knee pain be treated?

We must say that if the sound of the knee or the so-called Crepitus of the knee is not accompanied by other symptoms such as pain, swelling of the tissue, emptying, weakness, muscles around the knee and such symptoms should not be a concern. In these cases, the sound is probably due to the movement of tendons and ligaments on the joint surfaces when the joint moves or due to the bursting of gas bubbles in the joint fluid when bending and straightening the knee.

In these cases, you will not need to be examined and no diagnostic treatment will be needed if you hear a cracking sound from your knee and in addition to Crepitus, you will see pain and symptoms such as swelling and inflammation, redness, sagging and locking of the knee or amplitude of joint movement. Your knee has shrunk. In these cases, you should see a doctor for diagnostic procedures and necessary examinations.

In cases where there are other symptoms associated with the sound of a knee fracture, or if the Crepitus sound is caused by the knee following a trauma injury, an accident, or a sports injury, a doctor should be evaluated and the doctor prescribed treatment according to the underlying cause of the Crepitus.

Treatment options vary depending on the underlying cause of the Crepitus and the sound of the knee breaking. For example, sometimes there are ruptures of the meniscus of the knee and knee surgery may be suggested by a doctor Also, sometimes, at the doctor's discretion, a standard knee brace can also be used as well as knee rest to balance the knee injury and reduce knee noise.

The sound treatment of the joints of the body generally depends entirely on their underlying cause. If cryptocurrency of the knee is caused by a major and serious problem, a specialist doctor must perform a specific examination. Perform specific imaging to be able to identify the underlying cause and determine treatment based on it. Among the methods that are generally used in the treatment and reduction of noise in the joints of the body, we mention the following:


  • rest

If there is joint noise and the cause is joint damage, you should try to balance the injury and reduce joint noise by resting and limiting activities during which the sound intensifies. The important point is that doctors do not recommend absolute rest at all, because after a long rest of immobility, the surrounding muscles that actually support the joint become weak and the joint problem intensifies.


  • Exercise

Exercise can strengthen the muscles adjacent to the injured joint. When the muscles that support the joint are strengthened and the joint is more stable; Therefore, the occurrence of abnormal sound is reduced. We should note that in athletes, the sound of the knee may have occurred due to serious injuries and rupture of the knee tendons, rupture of the meniscus or softness of the patella of the knee.


Exercises include leg relaxation exercises, squats that strengthen the muscles in the inner thigh, and the release of hip flexor muscles, which should be performed under the supervision of a specialist to reduce the sound of the affected knee joint.


  • Massage therapy

With the effect that professional and specialized massage has on stimulating blood flow, it can make you feel relaxed and relieved after the massage. Massage can also relax the muscles and more blood reaches the joint and the nerve pressure on the knee is reduced so the joint sound is reduced.


  • Surgery

Most cases of ringing in the joints of the body, including ringing in the knee joint, can be relieved with simple, minimally invasive treatments, but if the cause of the knee joint pain and ringing is disorders such as patellar chondromalacia and knee dislocation, In these cases, the only treatment for knee ringing is surgery.
