However, I have found that many patients have a lot of unscientific knowledge about degenerative knee disease, some of them even believe in folk medicine and are misled by bad TV commercials, which delays the best time for treatment. The author now lists some of the relevant knowledge of degenerative knee joint lesions as follows. 1, what is degenerative knee joint degeneration knee joint degenerative changes also known as knee osteoarthritis, is the knee joint joint surface cartilage destruction leads to joint surface is not smooth, negative gravity line changes, so that the knee joint and the knee joint surrounding tissue degenerative changes after a lesion. The most common form is knee osteophytes on X-rays, so many patients always say they have “osteophytes” instead of arthritis, and always associate arthritis with sepsis or infection, but in fact knee osteophytes are only an X-rays of degenerative changes in the knee. In fact, in the work and living environment, the chances of rheumatoid arthritis of the knee joint are rare. Many elderly patients tend to believe in the folk medicine prescriptions, oral glucocorticoid drugs (such as dexamethasone) or Chinese medicine containing hormones, although it can play an immediate effect, but such drugs are through the suppression of the body’s normal immune regulation to achieve the analgesic effect, time will appear weight gain, pain aggravation needs to increase the dose of drugs to relieve pain, not knowing that At this time, the knee joint lesion is already very serious, and when you come to the clinic, you want to be treated by surgery but lose the time to operate because of long-term use of hormonal drugs. 2. How to treat degenerative knee joint degeneration According to the pathophysiological changes in different periods of degenerative knee joint degeneration, the author synthesizes the clinical manifestations and x-rays of patients, and the treatment focus is different in each period. In the early stage of degeneration, because of the early onset of the disease, the treatment is mainly based on preventive treatment, through appropriate rest, reduction of exercise, change of exercise, weight control and scientific exercise, simple medication, combined with physical therapy can achieve good results. In the middle stage of the disease, the frequency of knee pain increases, the joint swells, the X-ray shows mild osteophytes, and the joint deformation is not obvious. At this time, it is often necessary to do joint puncture to extract the fluid and then inject sodium vitreous acid into the joint cavity to lubricate the joint, and locally fumigate the joint with our self-developed Chinese herbal formula, together with physical therapy and oral medication to relieve the pain. For some patients, repeated conservative treatment for pain relief is not obvious, and surgical treatment is also available. In advanced disease, the patient’s joints begin to deform, flexion and extension are unfavorable, limping, X-rays show a change in the negative gravity line of the lower extremity, peri-articular osteophytes are evident, and the joint cavity becomes smaller or even disappears, so there is little point in any conservative treatment at this time. Of course, there are some patients who have severe degeneration of the joint cavity, and the upper and lower joint surfaces have begun to fuse, so the pain is not as severe, but the function of the joint is getting worse and worse. We Chinese people are often willing to endure a long time of pain and prefer not to have a good quality of life rather than surgery, or only come to the doctor to see if there is a good treatment when the disease has become very serious, so the films I showed to my instructors during my two visits to Germany surprised them that there are still such serious knee osteoarthritis. In fact, prolonged severe joint pain not only affects walking, but also has a negative impact on the patient’s nervous system and heart function. In fact, knee arthroplasty is now an effective treatment for osteoarthritis of the knee recognized by the medical community at home and abroad, and is also a very mature surgery and the ultimate treatment for osteoarthritis of the knee. It is equivalent to a “braces” type of knee joint surface replacement. Many patients are always worried about whether they will be unable to get out of bed after surgery or whether they will have to lie in bed for the rest of their lives or something like that, but this is actually a misunderstanding of the surgery. Our department has achieved very good results in treating advanced osteoarthritis of the knee with this surgery, which can significantly relieve pain, correct joint deformity and restore joint function, and the surgery can be completed within 70-90 minutes with minimal bleeding. After 2-3 months of recovery period training, you can resume normal life.
