Recently, a video of a "dodge step" slice went viral on the Internet, triggering a large number of imitations and creations by netizens and celebrities. It is understood that the video clip comes from an Anhui Huagudeng dance instruction video, and the "dodge step" is one of the basic skills.

Internet celebrities take turns becoming popular with their actions
Potential risk of injury cannot be ignored
With the popularity of the "Flip Step", the Affiliated Hospital of Yangzhou University issued a document stating that the orthopedics and sports medicine departments of many hospitals have received many young patients one after another. They all followed the trend and practiced the "Flip Step" and suffered knee injuries. After examination at the hospital, it was found that the cruciate ligament was strained or even partially torn.
Not only "stepping aside", blindly following the trend and imitating these "influencer moves" also carries potential risks of injury.
Card Chair Challenge
That is, inserting the legs into the armrests of the chair, or inserting the head and arms into the plastic stool. Most challengers get their legs or heads stuck during the process and are unable to break free.
Cross-legged holding pillar
He chose trees, telephone poles, etc. on the roadside, and wrapped his legs around the pillar like twisting twists. He challenged whether he could untie himself, but in the end his legs were locked and he could not move.
"Lying Fish Challenge"
"Louyu" is originally an opera move, in which an opera actor kneels sideways, crosses his legs, and slowly sinks his body. After the popularity of the TV series "Protagonist", many netizens began to challenge it. However, many people did not master the method during the challenge, causing their knees to "crack" and make abnormal noises.

It’s fun to follow the trend
Blind imitation can easily cause damage to knee joints
"Dodge step", "cross-legged hugging pillar", "lying fish"... These "Internet celebrity moves" are fun to challenge, but they also need to be vigilant about the possible damage to the knee joints.
"Dodge step" originated from Anhui Huagu Deng and is one of the basic skills of professional dancers. Professional dancers rely on their core and lower limb muscles to stabilize their center of gravity, but most ordinary people only imitate surface postures: their feet are nailed to the ground, their upper body turns sharply, and the sudden shift in their center of gravity causes the knees to be forced to rotate at an excessive angle. The shear force generated is a typical cause of non-contact tearing of the anterior cruciate ligament.
The cruciate ligament is like a "safety belt" that stabilizes the knee joint. It is tough but basically unable to heal itself. Ordinary people have weak muscle strength and poor joint stability. Without warm-up, they perform explosive twisting movements. The instantaneous force may loosen or tear the ligaments.
The "cross-legged holding column" movement presses down the body's own weight and tightens the legs to form a "self-locking". The knees, hips, and ankle joints are in a twisted and compressed state, which can easily damage ligaments and menisci.
When ordinary people imitate "lying fish", the knee is deeply flexed, loaded and twisted, and the meniscus and ligaments will bear huge shear force. Although the knee joint can rotate slightly, multiple forces are superimposed. Once imbalanced, it may cause meniscus tear, ligament damage or even patellar dislocation.

Avoid high-risk internet celebrity actions
Here are some other things you can do to take care of your knee joints:
As an important "bearing" and "load-bearing" joint of the human body, once the knee is injured or excessively worn, it will cause irreversible losses. Since the consequences of injury cannot be ignored, we should pay more attention to the protection of the knee joint. In addition to avoiding high-risk internet celebrity actions, daily knee pads can also do these four things.
control weight
The knee joint is the main load-bearing joint of the human body. For every 10 kilograms of weight increase, the weight-bearing burden of the knee joint will increase by an additional 30 kilograms. Long-term overload can easily accelerate cartilage wear and induce joint degeneration. Losing weight can help reduce the burden on weight-bearing joints and reduce wear and tear on the knee joints.
Eat a balanced daily diet and supplement nutrients in time
Daily diet should be balanced and nutritious. For healthy adults, sufficient calcium and vitamin D can be obtained from foods such as milk, fish, eggs, and soy products.
Menopausal women, osteoporosis patients and the elderly with poor absorption capacity are recommended to take calcium tablets under the guidance of a doctor; for those with vitamin D deficiency or insufficiency, it is recommended to take vitamin D supplements under the guidance of a doctor and spend more time in the sun.
Keep warm
When the weather is cold in autumn and winter, you can keep your knees warm by wearing long johns and knee pads. In summer, although the weather is hot, air conditioners and fans are used more frequently, which may make your knees cold. You can put a blanket on your knees to keep them warm.
Avoid long-term fixed postures
In daily life, you should avoid standing, walking, and squatting for a long time, such as squatting on the floor to wipe the floor, or sitting on a low bench for a long time, so as not to increase the burden on the joints and accelerate joint degeneration.
Special reminder: Proper training can also effectively protect knee joints.
Elastic band resistance training can effectively activate these muscle groups, and seated exercises are highly safe and can be practiced at home. Experts recommend two targeted training movements: knee extension while sitting with an elastic band, and leg bending while seated with an elastic band.
