Square dance is a characteristic recreational activity that has emerged in the land of China. It has cultivated sentiment, enriched spare time life, can be active bones, can entertain the mood! In a certain sense, it helps to improve everyone’s interest in life. The advantages are certain, but the disadvantages are also there. As a shallow orthopedic surgeon, briefly say a little bit of their own views. There may be a lot of friends will spray me, will spit, but not spit not happy. Friends suffering from bone and joint diseases, such as knee cartilage damage, articular cartilage is similar to a non-renewable resource, the repair ability is very weak, after the injury in the continued stimulation of wear and tear will aggravate this damage, just like building a house, while building demolition, the speed of the building itself is not as fast as the demolition, the house will never be built. Square dance is a lot of upbeat rhythm, the movement is bound to some of the movements of the fast pace of change, for patients with unstable joints is a great injury, will aggravate the injury; meniscus injury, meniscus repair ability is also poor, after the injury is not the correct treatment, the injury will persist, improper activities will also aggravate the injury, resulting in disease symptoms more and more serious, increasing the difficulty of treatment and prolong the recovery This makes it more difficult to treat and prolongs the recovery time. Rehabilitation treatment should be carried out under the guidance of a medical professional. Each person’s disease is different, so don’t follow the clouds and blindly follow the example of others when you see what they are doing. Some patients often mention the word “they”, which has a wide scope, but usually they are fellow patients with similar medical knowledge, and they have very little experience to draw on. For those who do not have obvious organic lesions, it is still good to move the fine bones.
