Autumn and winter are the high incidence of arthritis. According to statistics, there are 236 million osteoarthritis patients in China, among which, knee arthritis has a higher incidence in osteoarthritis. It is worth noting that knee arthritis is getting younger and younger, and the poor living habits of young people, sedentary, standing, sports injuries, and women wearing high heels can all cause damage to the knee joint. Bad knee joint may be related to the lumbar spine Knee osteoarthritis refers to the degeneration of joint cartilage and structural disorders, causing gradual destruction and deformation of the joint, which eventually leads to serious knee dysfunction. Knee arthrosis in young people is mainly chondromalacia patellae, also known as early arthritis. If not treated with early intervention, the development of arthritis can seriously affect joint activities and can even lead to disability. In early arthritis, the knee joint is painful, swollen, and limited in movement, especially when standing up and going downstairs after an hour or two of sitting, and the leg can barely flex or extend. The pressure on the knee is greatest when a person is sitting, followed by standing, and least when lying down. Many people with knee discomfort just treat the knee, but do not know that the source of the disease may be in the lumbar spine. After the age of 20, the lumbar spine begins to age Like the shelf life of food, the human body’s joints also have a service life, to a certain age, the cartilage at the joints will become thin, soften, lose elasticity, and even shatter, causing osteoarthritis. In the past, knee osteoarthritis patients were generally over 60 years old, but now it is common to see knee patients in their 20s and 30s. The intervertebral disc, located between two vertebrae in the human spine, is a flexible, gelatinous material made up of multiple layers of fibrocartilage. As the disc thins and loses elasticity due to aging, the size of the intervertebral foramen and the structure of the lumbar vertebrae change, which can compress the spinal nerve and subsequently affect the thigh muscles and knee function. The human lumbar spine begins to slowly age after the age of 20, and the body no longer supplies blood to the intervertebral discs after the age of 20. Sedentary lifestyle, excessive exercise and high heels can put more pressure on the joints and accelerate the aging of the discs. Early knee osteoarthritis can be cured Early knee osteoarthritis can be cured through specialized pain management. It is important to note that once the knee joint becomes painful, swollen, and restricted in activity, it should be treated at the hospital as soon as possible, rather than mistakenly believing that it is a weak leg that will be cured by calcium supplementation. In addition, in daily life, you should get up and move around for a while, don’t lean on the bed and watch TV, and don’t participate in hiking and cycling if you already have knee discomfort. Exercise to prevent knee disease should pay attention to four points Warm-up exercises can help raise body temperature, increase blood circulation in the deep muscles, enhance joint flexibility, which can largely reduce the chance of knee injuries. It is recommended that 15 to 20 minutes of warm-up exercises be performed before exercise, including jogging, ligament stretching, muscle stretching, etc. In the case of low outside temperatures, warm-up exercises are best performed up to 30 minutes. Sports environment to be safe a safe environment is very important to prevent injuries. When playing soccer, basketball and other sports, do not go to a wet field after the rain, slippery feet when turning force is very dangerous for the knee. Do not forget to tidy up and relaxation activities after exercise can allow the body temperature, heart rate and other recovery to normal levels, effectively reducing muscle and joint fatigue and soreness after exercise, can also play a role in preventing injuries. Key parts of the focus on the prevention of sports to protect the body into two kinds: their own protection and external protection. Self-protection refers to the need to train some key parts to be stronger to protect the body, for the knee joint, strengthen the quadriceps exercise, improve the strength of the muscles around the knee joint, is beneficial to prevent knee injuries. External protection is mainly through sports braces to protect the knee from damage.
