For a long time, there has been a saying that "running is only good for the knees". Whether regular running can easily lead to arthritis has also been controversial. American Journal of Orthopaedics and Sports Physiotherapy, an internationally renowned authoritative medical journal, has published an article, giving a conclusion on this controversial topic. According to the Journal of Orthopaedics and Sports Physiotherapy, the incidence of arthritis is 13.3% for competitive runners, 10.2% for sedentary runners and only 3.5% for fitness runners. Excessive high-intensity running may cause joint problems, but for ordinary fitness runners, running is good for joint health. Does "healthy" running hurt your knee? Stop arguing, the conclusion of the authoritative American medical journal is coming! The conclusion of Journal of Orthopedics and Sports Physiotherapy that fitness running is beneficial to knee joint health comes from a meta-study in this issue, which is a systematic review and meta-analysis: the relationship between fitness running, competitive running and osteoarthritis of hip and knee. Meta-analysis refers to the systematic, scientific and comprehensive evaluation of many research papers on the same issue by scientists, eliminating those low-quality or unqualified studies, and then integrating and evaluating those high-quality studies with certain statistical methods, and finally drawing scientific conclusions and suggestions.

The research was conducted by a research team composed of researchers from the United States, Canada, Spain and Switzerland. From the 25 studies with a total of 125 and 8 10, seven studies with a total of 1 14829 people were selected for meta-analysis. The study found that only 3.5% of fitness runners suffer from knee or hip arthritis, which is the same for both men and women. Among people who like sedentary or not running, 10.2% suffer from knee arthritis or hip arthritis. The incidence of knee or hip arthritis among people who participate in competitive running (including athletes who often participate in competitive competitions and professional level) is slightly higher than that of ordinary people, but it is not particularly high, accounting for 13.3%. Researchers point out that long-term fitness running-10 years, 15 years or even longer-is a healthy exercise, which is good for the health of knees and hips.

So how to maintain its stability? You need to do three things: joint alignment, strength balance and flexible hip joint. Human knees are straight. If there is internal buckle during running, the pressure on ligament, soft tissue and meniscus can be imagined. It can be said that most lower limb injuries are related to joint dislocation or force line dislocation. Because the joints are not aligned, they cannot be well buffered, or the force that should be buffered by the thighs or buttocks is transferred to other places, which will lead to injuries over time.
