Recently, a member of a male singing group and former Hong Kong Youth Football player, Chan Kin On, sprained his left knee in a "sanitary" soccer match, and his anterior cruciate tricuspid was reimbursed.
After discussing with the physiotherapist, one of the external factors that were not taken into consideration was the venue and the boot. They had heard that many people with knee injuries had their whole family on simulated grass, depending on the generation of the simulated grass field, which I don't know much about, but I had my whole family on a simulated grass soccer field in Hin Tin and I had my first time to play on this field, with a short rubber nailed to the boot, and at that moment of the whole family, I felt that my foot was stuck to the ground, and then I had a knee injury when I swung my head. Then my knee swung and I got hurt. Has anyone else suffered this kind of injury?
After listening to the therapist, I feel a little bit better, but at the same time, I feel helpless and doubtful. Is there any department responsible for collecting the data of injuries in the stadium and then study and improve the situation to minimize the chances of further injuries?
I have long thought of the LCSD's official answer: There are no relevant data. In general, for injuries sustained at LCSD venues, unless the field staff have to call the emergency ambulance to take the injuries to the hospital and the staff have to record the incidents, the field staff certainly do not have any record of ankle sprains, tibia injuries commonly known as "fried Chinese kale", and injuries to the anterior tricuspid altenori (ACL), the medial tricuspid altenori (MCL), and the cartilage meniscus, the "nightmare of football players". Without data, how can we study whether these artificial turf will increase the risk of injury or not?
A quick glance at the data that can now be publicly scrutinized is

There are just numbers for American soccer. According to Gosnell's account, the first generation of simulation of the surface of the nylon surface layer of the grass because the ankles will be soaked, indeed, will be easy to lead to lower limb injuries, the material is also easy in the player fell on the abrasions. In the second generation, the nylon surface layer became polypropylene, the bottom layer also added a layer of rubber, and then underneath the original soil infill became silicone particles, which improved the smoothness of the entire surface. This second generation of artificial turf has still been exposed to a significant increase in injury rates, and the chances of skin abrasions are even more disastrous.
In the third generation, in order to improve the problem of skin abrasion, the surface of polypropylene becomes polyethylene, and the fibers become longer; and the artificial mudni inside is not only silica gel, but also added rubber, other polymers and others, such as coir, cork and walnut shells and so on. To the next four, five, six generations of surface, are filled with material changes, different simulation turf companies are different materials as a business recruitment, did not bring too much of a breakthrough for the sense of foot.
One of the more accepted theories among players is that artificial turf has more friction on the boots (especially the outer ones), which makes it easy to sprain the ankle or knee when suddenly slowing down or turning around. The density of the infill and whether the shear force affects the swaying of the artificial grass when it hits the ground will determine whether the landing point is stable or whether there is room for the foot to float and cushion after landing.
A) Spikes have no position in the state. B) Slight displacement of the cleat, the padding is picked and piled up together with the cleat causing cushioning C) The density of the padding is so high that the cleat is blocked from being filled in, the cleat is stuck in the padding, and the shear force is transmitted to the ankle and knee.

Major League Soccer has for years commissioned the consultancy firm IQVIA to conduct a relevant study to examine the lower extremity injury rates of natural turf and artificial turf, excluding other risk factors. As a result, data from recent years show that there is no longer a significant difference between the two types of turf.
I couldn't find a chart for 2022, but according to ESPN's Kevin Seifert, the injury rate for 2022 is 0.048 per 100 hours for synthetic turf and 0.035 per 100 hours for natural turf.The numbers are still higher for synthetic turf, and Gould's systematic review has similar data, and points to the fact that a few of the studies that show higher injury rates on natural turf fields than synthetic turf are funded by synthetic turf companies. Gould's systematic review had similar data and pointed out that a few of the studies that showed higher injury rates on natural turf pitches than on artificial turf were funded by artificial turf companies.
Both the Gosnell article and the AP article point out that the switch from natural to artificial turf was due to cost and weather issues. It is not true that Hong Kong has never used real grass, but the more experienced fans are familiar with the lawsuit between the Hong Kong Stadium and the British Wembley Company back then and the

The image of the visiting tournament asking the players to "ghost eat mud" should be still fresh in our minds.
