I often hear people report that their knee joints make abnormal noises, with or without other discomfort. Could this have an impact on your health? It turns out that knee rattling is a phenomenon that cannot be ignored, and many diseases of the knee joint are related to it, which, if prolonged, can lead to a serious disaster! It is a common disorder in the knee joint. When the knee joint is obstructed by certain factors, the joint flexion and extension activities will emit sounds and vibrations, which is called a popping knee. What should I do if I have a popping knee? First of all, do not panic. Observe the knee for a few days to see what the characteristics of the popping sound are. Is there any other discomfort associated with it? Is there any aggravation or recurrence? If you are not sure, it is best to find a specialist in this area and go to the hospital for a checkup, and if necessary, to take frontal and lateral x-rays of the knee joint, and if you suspect patellofemoral arthropathy, to take bilateral axial patellar films, or to directly perform MRI of the knee joint. The following is the relationship between some related diseases and the popping sound. At first glance, it may seem complicated, but in fact, most of the popping in the knee joint is a mechanical disorder due to congenital, developmental, injurious, degenerative, or tumorigenic lesions in the joint. The presence of popping has important clinical significance. In clinical practice, it is relatively easy to identify the source of the popping sound and diagnose meniscal injury, disc meniscus, and osteoarthritis, while synovial crepitus syndrome and intra-articular ligament injury of the knee are difficult to be clearly identified by physical examination and can be easily confused with meniscal injury. It has also been found that some of the patients with snapping hips have abnormalities of the iliotibial bundle, which can also lead to disorders of knee motion. Since each disease has its own characteristics, a comprehensive and accurate diagnosis can only be made by combining history, physical signs and imaging examinations with arthroscopic dynamic observation. Although simple joint popping is not painful and does not have a significant impact on the body, it does not require special treatment. However, if the popping occurs as a symptom of some knee disease, the primary cause should be treated and the necessary surgical intervention should be performed. This is where minimally invasive arthroscopic techniques, which are both diagnostic and therapeutic, become an important tool in the management of knee popping. It is possible to make an accurate diagnosis of the source of the rattling and the disease, and also to provide treatment measures, and the symptoms of the rattling can disappear completely in more than 90% of cases. If you see this, I believe that you will make a wise decision if you have joint popping!
