The most important thing in treating osteoarthritis (OA) is to educate patients to properly understand their disease and use appropriate methods of treatment. Some people believe that OA is a normal physiological process of the elderly, do not need treatment, or that there is no drug treatment. Obviously this view is incorrect, although the onset of OA is related to ageing, but not the determining factor, but also with genetics, obesity, microtrauma, mechanical stress, endocrine, immune and many other factors. Treatment methods also work and are still in the process of innovation. Some people believe that ultra-intense exercise can treat or prevent OA, so some people walk dozens of kilometers a day, or repeatedly climb mountains, ultra-intense dance, etc.. In fact, it is not, over 60 years of age, super-intensity exercise may aggravate or induce OA. exercise should be gradual, the key is to persevere. For frail, sick people should not exercise too much. Heart rate and pulse rate is the easiest way to reflect the size of the exercise, the appropriate heart rate after exercise = 170 – age (years). Some people only emphasize drug therapy, which is also incomplete, appropriate sports therapy, reasonable, flat micro diet, good habits for the prevention and treatment of OA are very important.
