A. Can people with osteoarthritis of the knee exercise? For most people with osteoarthritis of the knee, moderate exercise can be helpful. Most patients with early osteoarthritis of the knee can improve their joint symptoms or even disappear through lifestyle modification, as well as proper exercise and rehabilitation. Patients with osteoarthritis of the knee should avoid high-impact sports such as mountain climbing, horse stance, three major ball games, jumping rope, and going up and down stairs. Prolonged standing and squatting should also be avoided. In terms of exercise, we should follow the “middle way” and master the principle of “no or less weight-bearing exercise” to “enhance muscle strength and increase joint mobility” as the goal. In order to achieve the purpose of “increasing tolerance, reducing fatigue and enhancing resistance to disease”, the progress of osteoarthrosis can be prevented. Second, what ingredients can help osteoarthritis? There are many foods that can help people with arthritis fight inflammation. Studies have concluded that some fruits, vegetables, fish, nuts and legumes have anti-inflammatory and anti-aging effects, known as the principles of the Mediterranean diet, and are effective in treating arthritis. Fish such as salmon, tuna, sardines, herring, anchovies, scallops and other cold-water fish are rich in omega-3 fatty acids, which are known to fight inflammation and reduce blood levels of C-reactive protein (CRP) and IL-6, two inflammatory proteins. Nuts such as walnuts, pine nuts, pistachios and almonds, which are rich in protein, fiber and unsaturated fats, are ideal for suppressing inflammation. Fruits and vegetables are rich in antioxidants, which are very beneficial in eliminating free radicals from the body and have anti-aging and inflammation suppressing effects. The best choices are: colorful fruits and vegetables such as blueberries, blackberries, cherries, strawberries, spinach, tomatoes, broccoli, eggplant and green peppers. Is it useful to take collagen for knee osteoarthritis patients? There is a wide variety of adjuvant medications for osteoarthritis on the market, commonly known as collagen, which are mostly adjuvant medications containing glucosamine or chondroitin sulfate; although the treatment guidelines published by the American Academy of Orthopedic Surgeons do not recommend the use of this type of medication as a treatment for symptomatic knee osteoarthritis, this type of medication has some efficacy in terms of clinical efficacy, and the principle of this type of medication is that it has an effect on the cartilage matrix and synovial fluid of the knee joint. The principle of this class of drugs is to play a complementary role to the cartilage matrix and synovial fluid of the knee joint, and to promote the metabolism, repair and regeneration of cartilage by improving the matrix microenvironment, thus delaying the progression of the knee joint, and therefore can be taken as a preventive drug. Fourth, osteoarthritis of the knee without symptoms can not be treated Most patients with osteoarthritis of the knee after active treatment, or self-regulation, knee symptoms can be alleviated, or even disappear, the joint function is good, which does not mean that the knee joint from then on, the joint into a plateau – that is, the wear and tear of the joint and At this point, the joint enters a plateau phase – a new balance between the wear and tear of the joint and the joint’s self-repair mechanism; this balance is a fragile one and requires patient care. Therefore, patients with osteoarthritis of the knee can go untreated when they are asymptomatic, but they need to follow the aforementioned health care precautions.
