Osteoarthritis is a common bone disease. With lower temperatures and rainy days, osteoarthritis can easily recur and it is important to keep warm. Many people still have many misconceptions about osteoarthritis. 1, osteoarthritis is not the patent of the elderly osteoarthritis onset and age is closely related. In general, 70% of people over the age of 60 have osteoarthritis, and 80% of people over the age of 70 have osteoarthritis. In addition to age, osteoarthritis is also “female-preferred,” with the elderly, women and the obese being the ones who have a relationship with osteoarthritis. However, osteoarthritis is not the exclusive preserve of the elderly, some long-term over-exercise, such as gymnastics, wrestling, weightlifting athletes, etc., will also appear early degeneration of the joint, resulting in cartilage damage. 2 , osteophytes are not equal to osteoarthritis The osteophytes found through X-rays are not all osteoarthritis, simple osteophytes do not have the symptoms of pain and limited joint movement, only with clinical manifestations such as pain, leg straightening, squatting, etc., is osteoarthritis. 3, inflexible joints, to be careful forging In fact, like climbing, squatting up and down and other excessive forging of joints, will aggravate joint damage, not conducive to symptom relief. Swimming, walking, tai chi and other outdoor exercises are more suitable for osteoarthritis patients, can enhance endurance and mobility. 4, do not think that knee pain is trivial, rest on it There are patients who have knee pain, but do not take it seriously, do not have to go to the hospital for treatment in a timely manner, and therefore delayed the condition. Treatment of osteoarthritis requires different measures depending on the condition and age. For early patients, physical therapy is mainly used to improve joint function. If the pain is obvious, drugs such as Fotarine can be added. If necessary, surgical treatment is used, including osteotomy, arthroscopic cleanup surgery, and artificial joint replacement.
