Older people hiking do not forget to wear knee pads Older outdoor sports enthusiasts often complain of knee pain, especially after hiking and climbing, often knee pain, the elderly knee degeneration, especially prone to injury, this time to pay attention to, your knee joint may have received damage. 1, knee meniscus injury Meniscus is cartilaginous tissue, almost no blood supply, once the injury is difficult to heal, is the formation of post-injury joint pain. Surgical removal of the meniscus and removal of small tears and striated tears through endoscopic techniques is an easily accepted and effective method. Meniscus injuries do not always require immediate surgery, and the joint can still be moved by walking carefully to keep the knee stable. However, sometimes a small lobe can move due to uneven walking or uncoordinated posture and get stuck somewhere in the joint space and immediately become painful and unable to walk. The symptoms disappear immediately with a pop, so you should be aware of this particular phenomenon. 2, knee joint free body joint interlock is not only caused by meniscal soft injury, there is another reason is the joint free body, its volume is very small, the essence is a small piece of cartilage due to trauma or degeneration and other reasons from the joint surface off, shaped like a pea size, not ossified X-ray does not come out, can occasionally feel, and then do not know where to go, scurrying to move quickly, so also known as “joint It can also be stuck in the joint space, forming interlocking, repeatedly causing fluid in the joint cavity, which is often ignored because it is not painful. 3, chondromalacia patella Another common cause of knee pain is chondromalacia patella. Repeated sprains of the knee joint or unreasonable sports posture can cause wear and tear of the patellar joint surface, the cartilage loses its luster and elasticity, and some of the cartilage softens and falls off, causing pain when the patella is moved. Daily activities are still tolerable, but easily fatigued. A little more activity can cause knee pain. Too much walking or uneven roads can cause knee joint effusion and joint swelling, which is unpredictable during the journey. With timely rest, recovery is quick. In mountaineering once the knee joint pain, swelling, should immediately take rest, ice, braking and other measures, do not continue strenuous exercise or forced to continue mountaineering, which may make the development of injury to irreversible, for some patients who already have knee disease or injury, mountaineering knee weight, long exercise time, damage to the knee joint, do not forget to protect the knee joint, if If you have severe pain and restricted movement that cannot be relieved, you should go to the hospital in time. What should we do to prevent injury? In outdoor hiking, people often overlook a simple but effective protection measure, which is to wear a suitable knee brace. The knee joint is the center where the upper and lower leg bones meet, with the meniscus at both ends and the patella at the back. The patella is stretched by two muscles and is suspended before the intersection of the leg bones, sliding very casually, and in ordinary life, the patella is able to move in a small range of ordinary activities in the knee area because it is not affected by external forces or violent activities. Because of the excessive pressure exerted on the knee by mountaineering activities, coupled with the violent activities in mountaineering, it is easy to make the patella be moved apart from its original part, thus causing diseases in the knee joint area. The meniscus, which is the “soft cushion” of the joint, is easily sprained and damaged by external forces, sliding, and sudden turning, especially when the center of gravity is unstable. Wearing a knee brace can fix the patella in a relatively stable position and strengthen the role of the medial and lateral support bands, limiting the sudden turning movement of the knee joint to ensure that it is not easily damaged.
