Knee arthropathy is one of the most common diseases in people, especially in middle-aged and elderly people, and it tends to be more frequent with age. Patients with knee arthropathies have difficulty moving even an inch, which is not only annoying and painful for patients, but also a problem for clinicians. According to the anatomical characteristics of the knee joint, the knee is the most complex joint in the human body, and it is the pivot of the lower extremity with the greatest load and movement. The femur (thigh bone) above the knee and the tibia (calf bone) below it are the two longest bones in the human body, and because of their long lever arm, the knee joint is subject to high forces and has the highest chance of strain and trauma. The patella of the knee joint is also the largest seed bone in the human body, and the thickness of its articular cartilage is 2-3 times that of other cartilage, and the pressure and shear forces it is subjected to are large, so the incidence of softening of the patella is also up to an unusual degree, and aging with age is almost inevitable, coupled with the complex structure of the knee joint, which makes knee joint disease not only high in incidence and It is difficult to diagnose and treat, and it is necessary to take nerve blocks, acupoint injections, soft tissue closure, knee massage, joint cavity injections and other methods to provide the right treatment according to the different parts of the disease and the different types of diseases. Therefore, once the disease is diagnosed, it is important to go to a regular hospital. In addition, in order to prevent the occurrence of knee arthrosis, the correct preventive measures should be taken. Generally speaking, the twisting movement in the semi-squatting position is more wear and tear on the patella; in addition, the loose quadriceps ligaments and obese people can also make the knee unstable or heavy burden and become a cause of knee arthropathy; or due to the position fixed in the sedentary flexion position, can cause knee arthropathy. In the prevention of knee arthropathy, there are exercises that can be done to enhance the strength of the quadriceps, such as straight leg raises to enhance the strength of the quadriceps, and kneading the muscles around the knee such as the gastrocnemius, which are also beneficial to the knee. You can also do some necessary non-weight-bearing or less weight-bearing knee exercises, such as cycling, sitting or lying legs, swimming, etc. Weight loss is also an important measure, because the heavier the body, the heavier the activities of the knee joint, the heavier the symptoms, clinical observation confirmed that fat people knee pain than maltreating people, and the treatment is also more difficult, many patients reported that the weight loss of 2-3 kg, knee pain also reduced. In addition, avoid wearing high heels, at least continuously, because wearing high heels can cause the body to lean back and the knee joint to flex accordingly, increasing the pressure on the knee joint and inducing pain. In the sitting position should also avoid bending the knee too long, should often move the knee joint, and sitting bending knee angle should not exceed filter 90 degrees, preferably between 0-60 degrees, often play poker, mahjong people should pay attention to. People who play poker or mahjong frequently should pay attention to this. In terms of diet, they should eat foods with high calcium content, such as shrimp and bone broth, and if necessary, take calcium supplements. In conclusion, knee arthropathy is a common disease, multi-morbidity, seriously affect the quality of life of patients, it is caused by a variety of factors, but also should be prevented from a number of aspects, especially the middle-aged and older people should pay more attention to the prevention and treatment of the disease, in order to make their work and life free from the disease. So. Be sure to care for your knee joint.
