One of the most complex joints of a person is the knee. Knee joints are constantly exposed to significant loads, so this is one of the most vulnerable places in the human body. The appearance of pain in the knee, especially when bending, may be due to excessive stress, injuries, various diseases. But despite the fact that many diseases of the knee joint have similar symptoms, the causes of pain in the knees can be completely different .
The most common cause of knee pain is injury. It can be an unsuccessful fall on the knee, a strong blow to the joint. A long stay of the knee in an unnatural position can also cause pain. Such damage is accompanied by the following symptoms: swelling, hematoma, pain in the joint with and without movement. Sometimes pain is accompanied by numbness, tingling, or a feeling of cold.
Possible causes of pain in the knees are damage to the ligaments, tendons, knee cartilage, the inflammatory process of the periarticular bags, as well as the pathological conditions of other parts of the knee joint.
Pain, which is accompanied by stiffness of the joint, impaired mobility, sometimes joint deformation, soft tissue swelling and increased sensitivity in the affected area of the knee, is more likely to indicate arthritis or arthrosis. These are quite serious diseases that can be asymptomatic for a long time. With these degenerative diseases, the joint is not able, as before, to cope with the load imposed on it, which leads to wear of the cartilaginous layer of the joint. The causes of pathology are most often hormonal disorders, excessive weight, heredity. The previous injuries and injuries of the knee, ligaments, menisci exacerbate the degenerative process.
When the first signs of these diseases appear, a professional assessment of the condition of the knees is necessary. Untimely seeking medical help contributes to the progression of the disease, leading to a limitation of the functionality of the knee joint.
Often patients complain of pain and a crunch in the knee. A common symptom like a crunch in the knee joint, accompanies a considerable number of diseases of the musculoskeletal disease. However, it is worth noting that the appearance of a crunch or clicks can be a normal occurrence in a number of conditions, for example, cavitation. A large amount of dissolved gas is collected in the synovial fluid washing the joint, at some point gas bubbles increase the volume of the joint cavity, resulting in a characteristic click when moving. In children, such clicks can be caused by underdevelopment of the ligamentous apparatus, mismatch of the articular surfaces of the bone. Pathology is those cases when the crunch manifests itself for a long time and the other signs of joint inflammation mentioned above join in, including pain. The causes of knee pain in these cases can be caused by tendonitis, arthritis, arthrosis, bursitis, gout, and other diseases.
Timely appropriate treatment and at least minimal physical activity will help to solve the problem. Inaction can lead to muscle atrophy, weakening of the ligaments of the articular apparatus. Such alarming signals of the body should not be ignored; you need to choose some kind of sports hobby, do fitness or dancing, and gradually increase physical activity. This will prevent the occurrence of internal injuries that cause tissue irritation, strengthen muscles, improve blood circulation. And knee pain during exercise will occur less and less. If sports are contraindicated for health reasons, short but daily outdoor walks are needed.
Whatever the causes of pain in the knees, only a qualified specialist can correctly recognize them. He will establish the correct diagnosis, determine the cause of the pain, its location, the nature of the damaging effect and prescribe the necessary treatment.
