Knee osteoarthritis is a common disease of the knee joint. The main features of osteoarthritis include degenerative cartilage lesions and the formation of bone superfluities at the joint edges. 1. Symptoms When sitting up and standing on the line feel sore and uncomfortable knee, walking for a while the symptoms disappear, this is the early performance. After a long time, the development of the disease will appear activities can not relieve the pain, and up and down the stairs or squatting, standing up are some difficulties, need to hand on the knee to support to help. After walking more, the knee joint is somewhat swollen, or swollen so much that some yellowish fluid can be drawn out. If there is free body formation in the joint, it can affect the joint movement, and there is “joint locking” phenomenon from time to time, and finally the knee joint deformity appears. 2. Classification (1) Osteoarthritis is the most common form of arthritis and is generally considered to be a chronic progressive degenerative disease. It is characterized by chronic wear and tear of the cartilage. It often develops in middle-aged and elderly people, and in the early stages of the disease, there are no obvious symptoms or symptoms are mild. Early on, the disease often manifests as stiffness and discomfort in the joints, which improves with activity. Acute inflammation can occur with strenuous activity and is relieved by rest and symptomatic treatment. (2) Post-injury arthritis is an arthritis that gradually appears after trauma to the knee joint. The clinical manifestations are similar to those of osteoarthritis, but there is a clear history of trauma, such as fracture of the transarticular joint, ligament injury or meniscal injury. (3) Rheumatoid arthritis is an inflammatory type of arthritis in which the synovial inflammation of the joint is the main cause in the early stage, followed by erosion of the articular cartilage, resulting in severe loss of joint function and residual severe deformity in the late osteoarthritis clinical symptoms. Rheumatoid arthritis can occur at any age, mostly in young people, usually involving both knees. 3, formal and effective treatment method Selecting a formal and effective treatment method without side effects is the key, Chinese medicine believes that knee arthritis is caused by wind, cold and dampness, Xiaoduo Treatment of knee arthritis is to dispel wind and cold, blood circulation and siltation for the purpose of following the principle of Chinese medicine through is not pain, so the effect is very thorough. Pay attention to prevent cold and keep warm. Knee arthritis treatment (1) conservative treatment: including drugs, massage, heat therapy, etc.. Most of the drugs are mainly painkillers, which can be very effective in relieving pain, but they have a lot of side effects on the gastrointestinal tract. (2) Surgical treatment: recurrent arthritis, and the joints have been deformed this is necessary to take surgical treatment. But if it has not reached that point, do not choose surgical treatment. Because surgery is traumatic and has many complications, it is not the best choice for patients; minimally invasive therapy: it can quickly reduce and relieve pain symptoms, delay joint destruction and restore joint mobility, stop cartilage and bone destruction, and prevent deformity and disability. Compared with the first two methods, the effect is better. It can gently relieve the pain and suffering of the disease.
