knee pain

Pain in both lower limbs, knee joint pain is the most common. Knee joint is composed of femur, tibia and patella, which is the largest joint, with the most complicated structure and more chances of injury.

Knee joint capsule, thin and loose, attached to the periphery of articular cartilage. Ligaments around the joint capsule are strengthened. The anterior patellar ligament is called patellar ligament. On both sides of the patellar ligament, there are medial and lateral patellar retinaculum. Posterior popliteal oblique ligament was strengthened; The medial side has tibial collateral ligament; The lateral side is the fibular collateral ligament. The synovium of the joint capsule is very wide, and all the structures in the joint are covered with a layer of synovium except articular cartilage and meniscus. There are also suprapatellar bursa and wing structure. The former can reduce the friction between tendon and bone surface, while the latter can increase joint stability and cushion vibration.

Pain in the front of knee joint is more common in patella injury, such as chondromalacia patellae and infrapatellar fat pad injury. Chondromalacia patellae, that is, chondromalacia patellae, refers to patellofemoral osteoarthropathy caused by swelling, degeneration, loss of luster, and finally cracking and falling off of patellar cartilage after chronic cumulative injury, and the same pathological changes also occur in femoral condyle cartilage. Its main symptoms are deep patella pain at the beginning, obvious at the beginning of exercise, relieved after a little exercise, aggravated after too long exercise, and relieved after rest; With the extension of the course of the disease, it is particularly difficult to squat, go up and down stairs, climb mountains and climb slopes, and even suddenly fall.

The infrapatellar fat pad injury refers to the edema and exudation of infrapatellar fat pad caused by acute injury or chronic strain, which leads to aseptic inflammation, adhesion of patellar ligament and fat pad, and restricts knee extension of knee joint. More common in people over 30 years old, they often climb mountains, squat or walk. The main symptoms are soreness, pain and fatigue of knees, especially patellar ligament and knees. When the knee joint is completely straight, the pain is aggravated, and sometimes the pain of the knee joint can radiate backward to the popliteal fossa.

Knee pain is related to overwork of lower limbs. Try to avoid squatting or weight-bearing activities. During the treatment, it is necessary to appropriately reduce activities and pay attention to keeping your knees warm.

As you get older, do you often have bouts of pain in your knees when you walk or climb stairs, or do you find that your knees will make a noise with severe pain when you squat down and get up? All these signs indicate that your knee joint may be in a state of degeneration. Its harm is roughly as follows:

1. Knee arthritis

First of all, the most common and common is knee arthritis. The most obvious performance is that you will feel slight pain when walking everyday, because the pain is not serious and will be relieved after rest, so most people will not take it to heart at first. However, if we don't pay attention to it, the situation will deteriorate step by step, and it may be difficult to stand. The most serious thing may be to replace the artificial joint.

2. Knee fossa cyst

Speaking of the cyst of the knee fossa, you may not be familiar with it, but its symptoms are familiar to everyone, that is, a big bag will swell behind the knee fossa. People often mistakenly think that they have a tumor. Actually, it is not. It is because of the serious degeneration of the knee joint that the knee joint capsule has been ruptured, and the joint fluid in it flows back into the joint capsule, which causes the knee joint to swell into a big bag, which will become bigger and bigger and have obvious pain.

3. Synovitis of knee joint

This situation is more serious. Synovitis of knee joint can lead to hydrops of knee joint, obvious swelling and fever of knee joint, difficulty in walking and obvious pain. In the worst case, it is impossible to walk, resulting in stagnant water and disability.

Seeing this, have you already felt the serious consequences of knee joint degeneration? How to solve this? In fact, for anyone, knee joint degeneration is a normal phenomenon. As long as we take precautions at a certain point, we can effectively slow down the speed of knee joint degeneration. Then how should we judge whether our knee joint has degenerated in our daily life?

First of all, everyone should pay attention to whether the knee hurts when it is pressed. Generally, after the knee joint is compressed, the superficial cartilage on the surface will play a buffering role, so it will not feel pain. However, after the knee joint degenerates, the cartilage surface will also degenerate, which will not play a buffering role, so you will feel pain when you press it.

Secondly, pay attention to unexplained joint pain when going upstairs and downstairs. Under normal circumstances, when we go up and down the stairs, the joint surface is protected by smooth cartilage, and some joint fluid is also playing a role in lubrication. However, after the knee joint degenerates, with the decrease of cartilage protection and joint fluid lubrication, when we go up and down the stairs, the knee will have unexplained pain. Also, when doing some lower limb exercises similar to squats, pay attention to whether the knee joint hurts. Because the knee joint is used as much as possible in lower limb sports, you can also feel whether there is any problem with your knee joint most obviously.

Of course, if your parents have backache and difficulty walking, they will be very tired when they do some housework, and their body resistance will be poor when they sleep.
