As people get older, they are more likely to develop osteophytes in their joints. This is also known as “osteoarthritis”. It is most common in the knee joint. Specific manifestations: 1. Knee pain, which increases after walking. Some people have pain when they start, which is relieved after a few steps. 2. Difficulty squatting. Or can not get up after squatting. 3, joint effusion. 4, X-ray film can be seen bone spurs, joint space narrowing. After getting osteoarthritis, what should I do? 1, first of all, reduce the amount of activity to avoid further wear and tear of the joint. 2, do not do strenuous activities, do not climb mountains, climb stairs as little as possible. 3, pay attention to keep warm. 4, early to mid-term, or mild to moderate: oral glucosamine capsules, observe half a month, if effective, can be long-term or intermittent. Why do you advocate taking this medicine? In the early to middle stage, the articular cartilage still exists, but the thickness is reduced and the quality is deteriorated: glucosamine is the main component of articular cartilage, and supplementing it at this time is the “cure”, and there are few side effects. In addition to glucosamine, sodium vitreous acid can also be injected into the joint cavity, with a similar mechanism. Injections once a week, 3-5 times for a course of treatment, the effect can be maintained for six months to a year. 5, in the middle and late stage: further degeneration of articular cartilage, the above drugs are not effective, you can perform arthroscopic clean-up, which is a minimally invasive approach, the incision is very small. Soon after the operation, the patient can move to the ground, and some patients can maintain the effect for several years. In the late stage, the above methods are not effective, walking and squatting are difficult, and the pain is unbearable. At this time, to improve the quality of life, artificial joint replacement can be done.
