Outdoor hiking, many people feel puzzled and questioned the role of knee protection, even holding "knee useless theory." This is not because the kneepad itself is useless, but it is likely that it has not found a kneepad that suits its needs.
Is knee protection useful?
The kneepad is useful, which is undoubtedly, especially for high-loaded hiking activities for a long time, wearing no kneepad is very different. According to research published by the North American Journal of Ergonomics, when walking uphill and downhill, knee pads can effectively brake the joints, reducing their displacement and stress.
In the case of bare legs, sleeved knee pads, and supporting knee pads, the treadmills were tested on the downhill and on the slope for 30 minutes. It is obvious that the sleeve knee pads and the supporting knee pads have reduced the knee joint displacement.

Although there are many real cases and studies that prove the efficacy of knee protection, some mountain friends still puzzled and questioned the usefulness of knee protection. This is because it is unclear how the knee pad works. On the other hand, because there is no suitable knee pad, there is no Under the symptomatic "medicine."
Finding a "pharmaceutical" that suits oneself needs to understand what role knee pads play. In fact, although the difference in the function of various knee pads is very large, the principle is summed up as nothing more than two points: warmth and fastening. For most mountain friends, knee pads are also very useful even if the knees are kept warm.
One of the functions of the knee protector: Keeping warm A lot of time the pain in the knee joint is due to the cold in the knee. The “thin meat†of the knee joint is the most likely to catch cold, especially when it is warm and cold in the mountains for a long time. It is easy to neglect the warmth of the knee joint and cause joint pain. At this time, it is necessary to add a layer of warmth to the knee. The purpose of many knee pads is to use it. here.
Why keep warm - When the knees get cold, the blood vessels in the knee joints contract, the blood circulation slows down, and the internal soft tissues have different degrees of damage due to lack of oxygen, and gradually affect the normal operation.
In addition, it should be noted that although the leg muscles are abundant, there is almost no muscle at the knees. In the marching mountains, when the legs sweat and feel hot, the knees may be at normal temperature, and when the legs feel cool and comfortable, the knees have already begun to catch cold.
The vasoconstriction at the knee joint.
The old cold leg - a form of rheumatoid arthritis. When it rains, the knee is very painful and hard to cure. The cause of the culprit is the abnormal immune response of the knee due to prolonged coldness of the knee: the immune cells misjudged their own cells as foreign invaders, attacked them, and damaged the knee cartilage and other parts.
Immune abnormal arthritis.
If you only need to keep your knees warm in cold regions and seasons, then you only need thick, warm knee pads.
Daily warm knee pads.
Warm knee pads can be simple and do not require excessive design, but there are a variety of knee pads on the market. These designs are designed to provide tightness to different parts of the knee. This is another great use for knee protection.
The role of knee protection: The knee joint pain is tight. In addition to catching cold, there is a major reason that the components are damaged. The role of the knee protector is to tighten the components to reduce the pain of the components and prevent further injuries. This kind of fastening, on the one hand, is to share the supporting force of the components, and on the other hand it prevents the knee joint from making large movements to further damage itself.

Why do I need to support? The meniscus, the sacrum, and the femur (the sacrum) bear most of the pressure on the leg. Once it is damaged, it will greatly affect leg function.
The supporting kneepads take a part of their pressure on their side, and transfer the load of the injured part through the hard part to other strong parts of the leg, such as the muscles of the thigh and lower leg.
Why is it necessary to brake? Once the leg has been subjected to large-scale powerful movements, it will cause displacement of the sacrum or ligament strain. These parts need to be rested after injury and the knees tightly wrap around the knee joint to brake these parts. To prevent them from making "extraordinary" moves again and further damage themselves.
Different knee joint injuries have different requirements for support and braking performance. Correspondingly, the kneepad design is also different. Understand where your injury is, and use the right medicine to play the role of kneepad.
Prevention of injury: The cylindrical soft knee-pad soft kneepad does not provide much support, but because of its tightly wrapped knee, it can also play a role in warming and braking. If your pain is light or you just want to prevent injuries, the simplest cylindrical knee pads are a good fit.
Meniscal injury: Supportive knee pads If you like to walk heavily, you go every month, and you don't have any bruises. However, the inside or outside of the knee begins to have pain, tightness, and snapping. When you go uphill, you suddenly have legs. To play softly, it is very likely that there is a problem with your meniscus.
The meniscus is responsible for the joint bearing, and its damage is the most common injury to the outdoor sports knee. Replacement of the meniscus with a supportive knee pad can provide effective relief of pain and injury.
Injury to the medial meniscus - when loaded, about 70% of the weight-bearing area is on the meniscus, and walking for a long time, the meniscus, which is cartilage, is prone to wear.
When the knee joint is bent, if the thigh abruptly rotates externally, causing the knee joint to twist, such as a sudden turn, and the body tries to correct this distortion, it may cause the meniscus tear. This situation is relatively rare wear.
Lateral meniscus injury – The principle of injury is similar to that of the medial meniscus, but it is less likely to be damaged than the medial meniscus because the medial meniscus is tightly connected to the joint capsule and the lateral meniscus is a free zone. The degree of displacement and deformation it can achieve is higher than the inside.

Supporting kneepads - Meniscal wear is due to prolonged high-load walking. Using a kneepad with lateral support, it is possible to share some of the load on the meniscus to protect the meniscus.
Ligament Injury: The bones and bones are fastened with a fast-supporting knee ligament to maintain the stability of the bone system (ie, the joint) during exercise, limiting its activity beyond the physiological range. Sudden strain on the leg, such as strong impact, stretching, and twisting, will cause strain or tearing of the ligament. At this time, it will be necessary for the knee brace to temporarily assist the ligament in maintaining joint stability.
Lateral Ligament Injury—A sudden stretch or twist in the course of a mountain climb, such as a side-to-side fall, climbs up and if you feel pain in the lateral side of the knee, it can be a pull or tear in the lateral ligament.
Injury to the medial ligament - When the lateral side of the knee joint suddenly erupts violently, it will tear the medial ligament; when the knee joint is in a bent state, sudden rotation of the lower leg can also cause rupture of the medial ligament. This kind of injury is more common in skiing.
Supporting the fastened knee brace - Ligament injury, affecting the normal movement of the knee joint, using the knee joint's tightness to limit the range of motion of the knee joint, coupled with the side of the support bar, can effectively relieve the ligament pressure and prevent re-injury.
Below-knee tendon pain: If you like jumping sports, if you feel pain and swelling on the lower edge of the patella, feel stiff or sore below the knee during or after exercise, your patella tendon may have a problem.
The sacral tendon is responsible for connecting the sacrum and thigh muscles. It has problems and it has to be protected with sacrum to prevent further compression of the sacrum.
Jumping knees - If the body has repeatedly performed knee flexion and jumping, it will soon exceed the maximum load that can be sustained by the tibial tendons, resulting in tendon damage. Accumulation of long-term subtle damage will result in "jumping knees". "Medicine is called "tibial tendonitis."
Tibia belt - knee pads for jumping knees is the tibia belt, it is a small ring, tied to the sacrum below the top of the sacrum, effectively prevent it from excessive pressure, damage to the tendon.
Note, however, that the tibial belt has little effect on ligament strains and meniscal wear. If you choose to wear just because of its small size and light weight, it is very likely that you will be disappointed.
Running Knee: Fixing the knee with the open-cell patella The running knee is a knee injury and pain caused by excessive friction between the patella and femur in the joint during marathon and cross-country races. The medical term is called "patellofemoral joint pain syndrome." In this case, you can use the open-cell patella to fix the knee pad and lock the patella in place without allowing it to run around.
Friction and displacement between bones - During running, the patella and the femur constantly rub against each other, making the cartilage between the bones under excessive pressure; or the imbalance between the inner and outer muscles of the thighs, making the patella unable to operate properly in the orbit, and moving the patella and moving the body. Uncoordinated, these will cause pain in the front of the knee.
Open hole patella fixed kneepad - often running and feel pain in the front of the knee, it is recommended to use an open patella fixed kneepad. As the name suggests, the kneepad exposes the shinbone to the outside and is reinforced with a ring of foam to stabilize the humerus and prevent the anomalous shift of the humerus. Such an open hole design also reduces the direct pressure on the sacrum to some extent.
Skeletal injury: When using a hard kneepad, when the skeleton of the knee is subjected to powerful external forces (such as vertical landing from high places, heavy objects, etc.), it is seriously worn, and even if it is fractured or dislocated, it requires a hard kneepad. Made of metal or hard plastic, with hinges, forming an artificial knee joint. For specific types of hard kneepads, consult a professional doctor.
Written in the final "frozen three feet a day cold", most of the injuries are the accumulation of multiple minor damage formed. You may not feel the effect of knee protection once or twice, but after a long time, you will find that you have a healthier knee joint than people who don't wear knee pads.
If you are a heavy-duty hiking enthusiast and the knee is not yet injured, wearing a pair of tubular knee pads will definitely benefit you. And if the knee has been injured, then finding the correct kneepad and prescribing the right medicine can also greatly extend your outdoor life.
