Let's start with the meniscus. 1. Early diagnosis and treatment are timely, and there is no big hematoma, and the symptoms are not serious, such as no "locking" or "locking" of the knee joint and no atrophy of the quadriceps femoris. If middle-aged and elderly patients or doctors judge that patients do not need surgery according to MRI, they may not need surgery. Some of these people can take part in sports like normal people, but that's a year and a half to two years later. 2. Athletes or sports enthusiasts who want to continue to engage in sports generally suggest surgery, but surgery is not a simple matter. In addition to the high cost, the recovery process also requires personal scientific rehabilitation exercise. In addition, we should know that the operation itself is a routine big trauma, and the knee joint function of a few people will be limited to a certain extent after operation. 3. Whether the injured meniscus can heal depends on the blood circulation state of the injured site, and there are enough blood vessels in the peripheral part of the meniscus (1/3). So generally speaking, compared with degenerative arthritis with worn and degenerated articular cartilage, it takes longer to help meniscus cartilage regeneration by ingesting our sawtooth cartilage powder, which depends on the individual's absorption ability and cartilage regeneration ability. 4. In addition to paying attention to the posture and intensity of exercise, we should also pay attention to sports protection, such as wearing sports protective gear to prevent accidental injuries during exercise. 5. In daily life, we should foresee the possibility of any accident and make full use of the tools around us to help reduce the risk of meniscus injury caused by accident. For example, when getting on or off the bus or going upstairs and downstairs, don't be too anxious. You can stabilize your body with the help of handrails before walking. People with professional habits should change their working posture and have a rest every once in a while. Joint Maintenance: The sooner you complete the "Joint Maintenance", the better. Experts believe that almost everyone will have joint diseases after middle age, but the onset time is different. Joint diseases have a lot to do with whether "joint maintenance" is appropriate when you are young. With the increase of age, various organs of the human body begin to age slowly, and articular cartilage will degenerate more or less due to abnormal metabolism, wear and aging. At this time, if the intervention measures of "maintaining joints" are kept up in time, it will get twice the result with half the effort. As we all know, joint diseases are caused by joint aging or overuse. In order to protect joints, strenuous exercise must be avoided. In fact, among the factors that cause joint diseases, sports mechanical injury is only one aspect, and there are many other details of life, such as overweight, standing posture, activity style, eating disorder and so on. , may promote joint diseases. Scientific diet is very important. For thousands of years, diet has been playing an important role in our health care, because only good eating habits can lead to a long and healthy life. Similarly, our "joint maintenance" is also closely related to our daily life. Exercise: Avoid strenuous joint activity and overload, prevent joints from bearing inappropriate gravity and violence, and reduce repeated joint injuries. If hip or knee joints are involved, people should avoid standing, running, playing ball or walking long distances. Sitting: Try not to sit for a long time, keep the same posture for a long time, and get up and move more in the middle. If your knees are stiff after sitting for a long time, you can do a "warm-up exercise" before standing up-gently swing your legs a few times. Sleep: Patients with cervical osteoarthritis should avoid sitting at the desk for a long time, raising their heads or turning their necks, and use pillows with appropriate height that conform to the curvature of the cervical spine when sleeping. People with lumbar involvement can sleep on a hard bed. Wear: Wear more elastic shoes, proper insoles, knee pads or elastic bandages, which are very beneficial to protect joints such as knees and buttocks. Usually pay attention to keep warm and damp-proof, so as to avoid joint inflammation caused by cold and wet stimulation. Diet: Overweight people should control their diet and lose weight to reduce joint load. Losing 5 kilograms can reduce the risk of arthritis by 50%. In addition, eat more foods rich in calcium and collagen. Here, supplementing collagen in vitro is particularly important for "joint maintenance". Because normal joints are composed of cartilage, joint capsule, synovial fluid and ligament, cartilage can protect joints and avoid bone wear. Collagen is the main component of cartilage tissue in joints, which is responsible for building the framework of cartilage tissue and shaping it. Whole bone nutrition makes your joints younger. The foods rich in collagen in daily diet mainly include pigskin, trotters, hooves and chicken wings. There are many inconveniences in cooking food such as pig's trotters and pigskin. Eating them every day is not only greasy, but also easy to gain weight, which is easy to induce coronary heart disease, hypertension and other diseases, and its effective supplement is also rare.
