Doctors call Knock on the knee and tapping the knee another term for cryptography. Many people describe this crepitation as the sound of a knock or a broken knee during their lifetime when they get up from a sitting position or when they bend down to pick up a box from the ground. We need to know that this condition does not only occur in the knee joint, but all of our joints can produce such a sound.

The knee joint is one of the main and large joints of our body, which is widely used in our daily lives. So it may sound louder than other joints, but the fact is that other joints can also cause this cracking sound.


What is cryptography or the sound of kneeling and banging?

The interesting thing is that when we talk about carbureting in medicine, we mean that if you put your hand on your knee and bend your leg straight from the knee, we can really hear the sound of something exploding and we feel something explode and something crumble under our hands.


Should we be concerned about hearing the sound of the knee?

In general, we should say that the sound of the knee should not always be a cause for concern, and the joints of many healthy people produce sound, and these sounds are completely normal and uncomplicated. In general, if the sound of the knee is a constant cracking sound of the knee and is accompanied by pain or swelling, limited movement of the knee, you should be worried and see a specialist to check it, but if the sound of a broken knee is occasional and Occurs when changing position or when bending and straightening the knee and is not associated with any of the above symptoms should not be a cause for concern.



The knee is considered a large and efficient joint in daily human life. This joint connects from the top to the end of the femur and from below to the large tibia. The tibia is also located in the tibia and participates in this joint.

The patella is a small, convex bone located in front of the knee. The cartilage of the knee is a thick cushion that reduces the friction of the participating joint bones relative to each other.

In the space between the upper and lower bones of the knee joint, there is a membrane called the joint capsule, and a fluid called synovial fluid is placed inside the capsule.

The menisci of the knee are two thick cartilaginous tissues that balance the pressure on the knee, and the knee ligaments will protect the knee in motion.


Why does knee ringing occur?

In this section, we want to classify the causes of crepitus of the knee or the sound of the knee breaking.

The following are two reasons why it can occur in a healthy person without joint damage and cause the crepitus of the knee to sound without symptoms.


  1. The first cause :the bursting of gas bubbles inside the joint

Inside all the joints of our body there is a joint sac and synovial fluid. This fluid contains substances such as nitrogen, carbon dioxide, and other gases that are soluble in the joint fluid. As the bones of the two sides of the joint separate, the space inside the joint increases and the pressure decreases, and thus these soluble materials become gas bubbles.

When we bring the bone surfaces around the joint closer together, for example when we flatten the knee, the space inside the knee decreases, the pressure inside the joint increases, and the gas bubbles get stuck in the wear between the joint bones, making the sound crackle. It is felt by most healthy young people with healthy joints when bending and straightening or when getting up from a sitting position.


  1. The second cause: ligaments, tendons, movement of ligaments and tendons relative to each other or wear on bones or cartilage

There are many ligaments and tendons in the knee that will protect and stabilize your knee joint. When bending and straightening the knee joint, these ligaments and tendons, which are connective tissues, may wear against each other or the ligament may Pull and make a sound when they are released.


This can also be one of the reasons why people experience knee tingling and a tingling sensation when bending the knee without swelling pain and limited movement.

Reasons for Knee Sounding Knocking sound of the knee joint along with other symptoms such as pain, swelling, locking, sagging of the knee is a reduction in range of motion.


  1. Runner Knee Syndrome or Patellofemoral Pain Syndrome

This syndrome is more common in young people and adolescents and in women than men; in which there is pain in the knee below the patella or on the knee with the sound of the patella. In this syndrome, the pain is more than the sound of a broken knee. Athletes who play basketball, volleyball, and soccer are more common in runners and professional jumpers.


It involves resting and applying a cold compress to the area where there is pain and under or on the patella. To relieve pain and discomfort, do not do activities that cause pain until the end of the discomfort period.

This is because the area where the patella is located is a groove in the lower front of the femur that has problems. In other words, the patella is not naturally located in its groove. Sometimes surgery is used to create a suitable position  for the patella.


  • Degenerative disorders of the knee ‌

Osteoarthritis of the knee, wear and tear of the knee joint is one of the most common causes of knee pain, knocking and crushing of the knee in addition to symptoms such as  pain, swelling, reduced range of motion, locking, emptying of the knee and instability of the knee in middle-aged and elderly people are knee osteoarthritis. In osteoarthritis, the natural structure of the knee is lost, its cartilage becomes fibrous, and it is no longer able to function. In this way, the bones adjacent to the damaged articular cartilage change to compensate for the insufficiency of the damaged cartilage. For example, bone growths cause misalignment called osteophytes. These misplaced protrusions may get stuck in the joint space as the knee bends and straightens. Sound may also be caused by wear and tear on the bones.


  • Rupture of the knee ligaments

One of the hallmarks of a ruptured knee ligament is that the injured person hears a very loud noise from the knee, followed by terrible pain in the knee.

Injuries to the internal collateral ligament in the human knee are much more common than injuries to the external collateral ligaments of the knee, but because the anatomy of the outside of the knee is much more complex, in these people it causes the external collateral ligament injury to be accompanied by damage to other joint components.


  • Rupture of the menisci

The menisci are actually thick disc-like cartilaginous structures that are two at the knee. If these menisci are torn, they may break a piece of bone, which means that there is a rupture of the meniscus in the sound of the knee, as well as locking of the knee and emptying of the knee in particular.

There are an estimated 27 million people in the United States with osteoarthritis, and middle-aged and older people are more likely to develop osteoarthritis with obvious clinical symptoms. Osteoarthritis affects the joints that humans use most in their daily lives. The knee and pelvis are among the joints that also support the weight of the body.


When should we see a doctor with the sound of a broken knee?

We have to say that calling the knee or crypt is not a concern in people who do not have a joint problem, it is painless, it has no other symptoms, and if the sound of your knee was accompanied by pain and other symptoms, it may be a sign of an important underlying problem.

Knee ringing is a common symptom and manifestation of people with osteoarthritis of the knee with pain.

Another point is that one of the symptoms of diseases called rheumatoid arthritis and their main one is rheumatoid arthritis and also infectious arthritis can be the sound of the knee and in all the above cases it is a serious issue and in addition to ringing in the knee there are other symptoms. There may also be involvement of several other joints at the same time, especially in rheumatoid arthritis.

Therefore, if the sound of the knee is accompanied by any of the following, you must see a doctor:

  • the pain
  • Swelling and redness of the knee reduce the range of motion of the knee
  • Sensitivity to touch
  • Joint instability
  • Joint locking
  • Emptying the knee



In diagnosing when a person presents to the doctor with a sound of the knee along with other symptoms, what the patient presents to the physician about his or her symptoms, as well as the mechanism that triggered the pain, plays a key role in reaching the physician due to the underlying cause of the knee ringing. Also, sometimes, after obtaining an accurate history, the doctor will perform standard physical examinations for the knee to find out the possible damage to your knee, and also, depending on the symptoms and conditions you have, the paraclinical may be used accordingly.

  • blood test
  • Blood culture
  • Articular fluid pulse
  • Joint fluid analysis
  • Articular fluid culture
  • Perform simple knee x-rays in a variety of positions
  • Arthroscopic MRI CT scan

It can be diagnostic and therapeutic in ligament ruptures, and in general in knee locks we may find and remove the involved part with our arthroscope.

For example, in a meniscus tear, which also involves the emptying of the knee, the knee is inflamed and noisy in the early stages. Diagnostic and therapeutic procedures can be performed through an arthroscope.



If you have a sound in your knee and the sound is not accompanied by other symptoms, do not worry, ringing in the knee should not be annoying. If a person has pain and discomfort with the sound of the knee while bending and straightening the knee joint, it is better to consult a doctor as soon as possible.

Knee ringing alone is harmless if it does not follow a serious underlying problem of trauma and injury and does not cause discomfort and annoyance, it does not need treatment. If knee pain is accompanied by pain and other symptoms, treatment of knee noise is actually treating the underlying cause. For example, a person with osteoarthritis of the knee experiences pain and other knee problems with ringing in the knee , in the standard protocol, the following should be done:

  • The first step is to change your lifestyle, for example, reduce your weight and balance it. Avoid going up and down stairs and moving sloping surfaces. Wear appropriate shoes. Avoid kneeling and jumping and walking on uneven surfaces.
  • Rest
  • Use cold compresses
  • Holding the injured leg high
  • Use of acids
  • tying the knee (temporarily)

In cases of pain, he can use painkillers, non-steroidal anti-inflammatory drugs, naproxen.

Avoid tying the knee for a long time; Because it weakens the ligaments and supporting muscles and makes the knee weaker, more vulnerable and unstable.

In the acute period, use standard braces only for a short period, only in acute periods, raise the leg, use a cold compress.

Sometimes cold and heat therapy will improve the result.

In the next step, if these measures are not effective, intra-articular injections are recommended before corticosteroid injections, ozone injections and lubricating gels.

Joint physiotherapy and strengthening the stabilizing muscles that support the knee are very important. We emphasize that after the acute phase, you should stop using the brace and start the movements little by little so that the knee returns to its normal range of motion. Standard physiotherapy to strengthen the muscles that support the knee plays an essential role in stabilizing and preventing pain attacks.


In case of ligament or meniscus injuries or other joint components, fractures in dislocations, etc, treatment is performed according to the condition. It is better to talk a little about the supplements that are available in pharmacy for cryptocurrency sound.


Glucosamine in combination with chondroitin sulfate

It is a common complementary treatment prescribed for many joint injuries. Fish oil, which can be high in omega-3s and has proven anti-inflammatory properties, and other ingredients that can be recommended as supplements, is usually available in tablets and capsules.

Herbal extracts are drugs that are claimed to be able to relieve joint pain and warm compresses and cold compresses have good pain relief, but we must say that the use of traditional therapies can not eliminate the underlying cause of pain.


Prevention of knee joint injuries

Exercise regularly Regular exercise strengthens the knee joint guard muscles. Resistance exercises Perform certain movements, such as a standard launch or squat, at least twice a week. Slowly increase the intensity of the exercises and the duration of them.


Before exercising, you should do stretching movements for the muscles in a completely dynamic way. Move the muscles in their range of motion. After exercising, stretch the muscles statically, that is, stretch your muscles (for 30 seconds in the same position).

Staying in this sequence prevents muscle and joint damage, so regularly strengthen the muscles in the front and back of the thigh, quadriceps and hamstrings in accordance with the exercise instructions given to you by your doctor.

Wear appropriate shoes and wear shoes that fit your anatomical condition. Use more minerals in your diet Fish oil is good for fighting inflammation. The root cause of many knee joint problems is inflammation. It is best to take a good supplement of natural antioxidants under a doctor's supervision to function properly in general health Obtain body and connective tissues.
