General ligament injury will cause swelling, pain and muscle spasm, sounds like a muscle strain, but in fact there is a difference between the two, first of all, the muscle is elastic tissue, ordinary strain is only a break in the muscle fibers, if not particularly serious is very easy to recover. A ligament strain, on the other hand, is a problem with the connection between bone and bone, and subjectively there is a feeling of instability, like building blocks, completely separated into two different parts. ACL (anterior cruciate ligament) injuries are a very common type of injury during regular training and sports. It is highly prevalent in professional sports, especially in soccer, basketball, and martial arts wrestling. The role of the ACL is to prevent the tibia from moving forward, so if the ACL is injured, it can easily cause subsequent injuries to the articular cartilage, meniscus, or other related areas. Cartilage injuries (meniscus, patella) There are two types of cartilage injuries that are most commonly encountered in the knee, one is patellar tenderness and the other is meniscal tears. Let’s talk about the meniscus first. The knee joint contains a curved cushion-like disk of cartilage, generally called the “meniscus”, which has a “C” shape and is composed of tough fibrocartilage – this may seem too abstract to you. You think it’s too abstract, but you’ll know when you’re chewing on a chicken leg, there’s a small piece of flexible and crispy bone near the bone. The cartilage disc of the human knee is actually similar to that of a chicken leg, wrapped around the bone like a small cap, and that’s where the “C” comes from. Of course, no one will unload human cartilage discs in batches and sell them together. …… Chinese editorial spicy chicken knee bones are very fragrant Oh! In fact, it is the “spicy meniscus” …… The knee joint has a meniscus on the inside and outside, the meniscus has the role of stabilizing the knee joint, helps lock the joint when standing, and plays the role of a cushion between the bone and the bone. I don’t know if you ever took a craft class as a kid where you piled a house out of a popsicle stick, but back then things like all-purpose glue weren’t available everywhere, so we all used chewed bubble gum to connect two sticks and make all sorts of shapes. The cartilage discs were similar to the gum at that time, and played a role in cushioning and shaping the bone. The normal meniscus calf is twisted and so on, the meniscus will be torn and when the knee is twisted rapidly, the meniscus will be damaged by the strong pressure …… finally, lightly leading to meniscus breakage and inflammation, or directly leading to meniscus tear. The patella is similar, the patella is commonly known as the kneecap, you reach down and feel it, it is the piece of the knee that is protruding. The patella initially serves to protect the knee joint from excessive friction of the thigh bone and to maintain the stability of the knee joint during bending. However, during sports, too much wear and tear and abnormal joint twisting can damage the patella cartilage. This can lead to chondromalacia of the patella. What can I do to prevent this? How do I choose a knee brace? As we mentioned above, many knee ligament, meniscus and patella injuries are caused by abnormal twisting or unstable movement of the lower leg tibia. It has been found that with strengthening and training of the leg muscles, joint injuries can be very effectively prevented. Of course, many students have said. nba, professional soccer players are the strongest group of people in the world in terms of leg strength. Why they are still partly speaking, they are involved in a sport that would have been very easy to cause them injuries (imagine you jump up and are trying to land, an O’Neill press on you ……). The other part, most professional athletes formally due to the movement of the active muscle strength is too strong, the antagonist muscle strength is not enough, resulting in the force after the trajectory of the movement is not stable and impact on the joints, it is easy to get injured. So in the training must ensure that the training parts of the balance. As well as the training of some small muscle groups, stabilizing muscle groups. Of course, the prevention of what is from the moment. Especially for those who have a history of injury, or those who are heavier, you can choose to wear some knee pads for sports. The general principle of knee pads is to give a certain amount of pressure to the joints to ensure that the movement of the joints is stable. At the same time, some knee pads can protect the joints when they have to twist or hyperextend abnormally. In general, beginners in sports can use this kind of ordinary knee pads, adjustable knee pads. But be aware that if the knee pads are not strong in elasticity and restraint, and just hang on, then they are not useful at all except for warmth ~ they still need some restraint to ensure the safety of the sport. For those who have more maximal strength training, you can choose this long knee strap. It has the strongest effect on joint stability and compression. For example, fitness shaping, bodybuilding, powerlifting friends can choose this kind of. Good for heavy weight training. It can protect the knee from abnormal movements at extreme weights. The disadvantage is that the protection of the trajectory of a single, binding feeling strong. Lovers of explosive and combined events, such as basketball and soccer, can choose this elastic fabric overall type of knee pads. It will not hinder explosive power. And the overall design generally takes into account a variety of sports situations. It seems to be Balfour for Dewar. If you care about weightlifting or Crossfit, you’ll also find that many weightlifters also use these more flexible overall knee pads. After all, weightlifting is an explosive sport. If you have a history of knee injuries, especially if you are rehabbing after an acute injury, you can use these knee braces. This is generally prescribed by the hospital doctor up brace, mostly carbon fiber plus high-tech alloy built. Maximum to ensure that the knee is not injured. There are also many special braces for post-surgery, such as meniscectomy and ligament reconstruction.
