What causes knee cracking?

Some people play with their fingers to look cool or because they are bored, making crackling sounds, but sometimes we make crackling sounds inadvertently when we are doing activities. Some people feel that they are sick or that there is something wrong with their bones because their fists make noises or their knees make noises when they go down the stairs. So, what causes cracking knee joints? Let’s take a look at the detailed introduction now.

In medicine, joint clicking is divided into physiological and pathological. Most joint clicking is physiological. When the joints move, friction and sound will always occur between the articular surfaces, between the cartilage pads and the articular surfaces, between the tendons and the joint capsules, etc. The sound will not cause discomfort to other parts of the body and is not harmful to the body, so there is no need to worry about it. Especially for young people, joint noises other than those caused by trauma are physiological.

There is also joint disease; some people experience discomfort such as soreness, swelling, etc. when their joints pop, which may indicate that there is a problem with the joints. Common clinical diseases include meniscus injury and patellofemoral osteoarthritis. This pathological clicking is common in the knee, ankle, hip, and shoulder joints, and is more common in the elderly.

Therefore, when pathological joint noises occur, some joint maintenance should be performed as soon as possible, such as supplementing with calcium. Here the editor recommends supplementing with biological calcium, and emerald casein calcium is very good. Otherwise, if the condition continues to develop, the joint cartilage will be worn out further and may lead to degenerative arthritis.

In life, we often hear people report that their knee joints make abnormal noises, with or without other discomfort. What is going on? Will it have an impact on my health? It turns out that knee popping is a phenomenon that cannot be ignored. Many diseases of the knee joint are related to it. If it is left unchecked for a long time, it may lead to serious consequences! Joint popping is actually a common manifestation of internal knee derangement. When the movement trajectory of the knee joint is hindered by certain factors, the flexion and extension of the joint will make sounds and vibrations, which is called popping knee.

First of all, don't panic. Observe for a few days to see what the characteristics of this popping sound are. Is there a sound or popping sensation in the knee when you move? Are there any other discomfort symptoms? Is it getting worse or coming back again? When you are confused, it is best to find an expert in this field and go to the hospital for a check-up. If necessary, take anteroposterior and lateral X-rays of the knee joint. If you suspect patellofemoral joint disease, take bilateral patellar axial films, or directly perform a knee joint MRI.

The occurrence of clicking in the knee joint is mostly due to mechanical disorder symptoms caused by congenital, developmental, traumatic, degenerative, or tumorous lesions in certain tissue structures within the joint. The presence of snapping has important clinical significance.

Clinically, it is relatively simple to identify the source of the clicking sound and diagnose meniscus injury, discoid meniscus, and osteoarthritis. However, synovial plica syndrome and intra-knee ligament injury are difficult to fully identify through physical examination and are easily confused with meniscus injury. In addition, the study found that a portion of patients with snapping hip have iliotibial band abnormalities, which can also lead to knee movement disorders. Because the snapping symptoms of various diseases have their own characteristics, a comprehensive and accurate diagnosis can only be made based on the medical history, physical signs, imaging examinations, and dynamic observation examinations under arthroscopy. Although simple joint popping does not cause any pain and has little impact on the human body, no special treatment is required. However, if the clicking occurs as a symptom of a certain knee joint disease, the focus should be on treating the primary disease and performing necessary surgical intervention. At this time, minimally invasive arthroscopic technology, which has both diagnostic and therapeutic functions, becomes an important means of diagnosing and treating knee clicking syndrome. It can not only make an accurate judgment on the source of the clicking and the disease condition, but also provide treatment measures at the same time. In addition, the clicking symptoms can completely disappear in more than 90% of patients.

Through the above introduction, I believe everyone should understand that knee joint cracking may not be caused by calcium deficiency. Everyone should take it seriously and don’t think that taking calcium tablets can solve the problem. It is best to go to the hospital for a check-up to see if it is a pathological or physiological problem. Don't just crack your knuckles for fun; it's not good for your fingers.
