Known as patellar tendinitis, the pain is located below the patella. Straighten your knees and press the lower edge of the patella with your fingers, which will make you feel sore, so patients often squat down and can't stand up. Many people often have to stand for a long time because of work, or because of overwork, or because they are athletes. Therefore, patellar tendinitis is also called "knee jumping". Treatment methods include rest, rehabilitation exercise, shock wave therapy, radio frequency or surgical treatment, and there are different choices according to the treatment effect and severity and the duration of the disease. If hyaluronic acid is injected as degenerative arthritis, the effect is not obvious.
2 Another common:
It's goose foot tendinitis. Often coexist with degenerative arthritis, but also exist alone, and the pain site is different from patellar tendinitis. The painful part of goose foot tendinitis is inside the knee joint and above the tibia. It will be very painful to press it with your fingers. Many patients with degenerative arthritis feel their stiffness and pain relieved after receiving hyaluronic acid injection, but they still feel pain above the medial tibia, which is caused by tendinitis of goose foot. At this time, you only need to inject a small dose of steroids into the pain area to improve the symptoms. Moreover, the dose of local injection of steroids is very low and there are few side effects, so people do not need to be afraid of steroids.
Another kind of pain also appears on the inside of the knee joint: but at the distal femur, when the knee joint moves, you can still feel a "click". Occasionally, the knee joint will ache or even accumulate water, which is knee joint wrinkle syndrome. Knee fracture is the residue of joint capsule during embryonic development, which can cause pain and hydrops when it is inflamed. It can be treated by anti-inflammatory painkillers, rehabilitation, steroid injection and even arthroscopic surgery. Another kind of pain in the distal femur of medial knee (especially when sleeping at night) may be knee joint necrosis, which is simply a "stroke" of knee joint bone. Young patients can receive cartilage transplantation, while elderly patients can receive partial artificial joint replacement. In other words, you can replace half of the joints and necrotic parts, not all of them.
Some patients with knee pain will find patella valgus after X-ray examination. In severe cases, articular cartilage of patella will also cause wear and degenerative arthritis. Early disease belongs to chondromalacia patellae. If the course of disease drags on for a long time, it may progress to patellofemoral degenerative arthritis. 80% of patellar valgus and chondromalacia can be treated by rehabilitation exercises (such as strengthening quadriceps femoris and relaxing posterior femoris), and a few cases must be corrected by lateral patellar relaxation surgery or even tibial tuberosity osteotomy.
People with high uric acid concentration in the blood tend to have gout. The big toe and ankle are the most common positions. In fact, gouty arthritis may also occur in the knee joint. Patients often wake up to find that their knees are red, swollen, watery and painful, which is probably a gout attack.
Knee joint is the largest complex joint in human body. Once the disease breaks out, it will often bring great pain and inconvenience. However, there are many reasons for knee pain, and it is definitely not the word "degeneration" that can explain everything. There are still many diseases that are not introduced in detail in this paper, such as rheumatoid arthritis, meniscus cartilage rupture, cruciate ligament rupture, lateral ligament rupture and so on. The author only describes some common diseases, hoping to improve everyone's understanding and have a preliminary judgment on the pain of his knee joint. But the most important thing is to find a good doctor with rich clinical experience to make a detailed differential diagnosis for you. After all, correct diagnosis is the first step to successful treatment. We often think that only professional athletes will have torn knee ligaments, but a research report from the University of Michigan in the United States says that the proportion of women's knee injuries in sports is four times that of men, and even some simple actions such as jumping, turning and twisting may lead to torn knee ligaments in women. In the United States, every year,10 million women seek medical treatment for knee pain, and the reasons for their injuries are often: moving things, climbing stairs and squatting for a long time ... Compared with this figure, 5.5 million women in the United States seek medical treatment for headaches every year. It can be seen that knee pain has become a more common female health problem than headache. Although women's tolerance for knee injuries is 6-8 times that of men, why should they end their career because of knee injuries like professional athletes? Knee injury is not only due to calcium deficiency, what makes women's knees so fragile? Researchers at the University of Michigan believe that the root cause of female knee injuries is not only calcium deficiency, but also the structure of female legs. The femur connects the hip to the knee. When the thigh is compressed, it will spread the pressure to the hips and knees. Once the leg muscles can't reach the balance of strength, it will cause injury. During exercise, women use quadriceps femoris muscle in the front of thigh more frequently than hamstring muscle in the back of leg, which easily leads to the imbalance of muscle strength between the two groups. Of course, we can't change the structure of the legs, but there are some simple and easy methods that can not only make the knees less painful, but also relieve the symptoms of knee pain that have already appeared. Beauty for your knee: I don't need a "steamed bun" knee injury. Phase 1: Analysis of the causes of kneecap pain: Among all female patients with knee joint injuries, the number of kneecap injuries is the largest. Edward, a professor of plastic surgery at the University of Michigan in the United States, explained: As the leg stretches, the kneecap slides up and down. However, in the process of exercise, women's kneecaps are easy to slip out of the normal trajectory and rub against the surrounding bones, causing kneecaps pain, even extending to the sides and back of kneecaps, and sometimes the "snapping" sound from kneecaps can be heard. Danger crowd: This kind of pain, regardless of age, may cause kneecap pain as long as you do activities that need to jump and go up and down repeatedly, such as cycling and climbing mountains. How to deal with it: If you have suffered from kneecap pain, don't panic. Professor Hannah Fen from new york Women's Sports Medicine Center suggested that kneecap pain can be cured as long as the exercise and adjustment are strictly carried out according to the exercise plan for kneecap tissue. To strengthen the endurance of knee joint, the length of exercise time and the increase of exercise intensity should not exceed10% within one week; Strengthen the exercise of leg adductor muscles, which exist around the kneecap to help it recover to a good position; To exercise leg adductor, you can learn from jane fonda, a famous Hollywood movie star: lie on your side on the flat ground, bend your thighs, put your feet flat in front of your calves, gently lift your calves, and then gently put them down, and so on 15 times. Knee Injury No.2: Analysis of the causes of knee swelling: When the knee is severely damaged, a meniscus cartilage at the knee will instinctively respond to protection, which is called meniscus in medicine. It can absorb the impact force well and distribute the force evenly to all parts of the knee. When this kind of cartilage is damaged, it will form swelling at the knee, which will aggravate the pain in severe cases, and the swelling at the knee is obvious, even forming arthritis. Risk group: women around 30 years old, even under 30 years old, often suffer trauma in outdoor sports, resulting in knee swelling; 40-50-year-old women, knee cartilage aging, resulting in weakened knee resistance, causing knee swelling; In addition, overweight will bring strong pressure to knee cartilage and accelerate its aging. Coping methods: Professor Hannafen suggested that applying ice cubes directly to swollen parts can reduce swelling; Then you need to do exercises to strengthen your knee strength and flexibility. If you feel pain in your knee for several weeks, but there seems to be no obvious injury, it is recommended that you seek medical attention immediately, because sometimes meniscus injury does not have obvious swelling, but it needs surgery to cure it. If you feel pain in your knee after strenuous exercise, don't wait 2-3 days to check it. To make the meniscus strong, you need to do strength and stretching exercises from hamstring, quadriceps, hip joint and knee to tibia. Please consult a professional fitness doctor for detailed methods. Knee injury 3: Analysis of the causes of pain above and below the knee: excessive exercise time or intensity leads to fracture, muscle strain or patellar tendinitis. At first, you may only feel slight or severe pain during exercise, but later, you will feel pain during ordinary daily activities and even during rest. Risk group: women aged 40-50, whose estrogen secretion and bone density decrease during this period, are vulnerable to this kind of injury. How to deal with the injury caused by this kind of excessive exercise requires rest until the pain disappears completely. To avoid this kind of injury in the first place, you should gradually increase your exercise. If you choose to run, please don't speed up and lengthen the distance at the same time. Professor Hannah Finn suggested that you should exercise according to your ability. Knee injury No.4: analysis of the causes of knee sprain: during exercise, when the body suddenly turns in a certain direction, the knee bends and swells, and it hurts when you exert a little force. This is because your anterior cruciate ligament is torn. Anterior cruciate ligament (ACL) is one of the four ligaments connecting femur and tibia of knee joint, which plays a fixed role in the rotation of knee joint. Risk group: anterior cruciate ligament tear, most common in high school and college athletes. However, all women who like sports should be vigilant to avoid this kind of injury, especially when they take part in some activities that require sudden turns, such as basketball and skating. Sometimes, falls, car accidents and even playing with pets can cause such injuries. How to deal with it: If you have torn ACL, please go to the hospital as soon as possible. Professor Hannafen suggested: to protect the anterior cruciate ligament from injury, please don't continue to exercise when you are tired; Avoid moving on uneven ground; Strengthen the strength training of hamstring and medial quadriceps; When landing after jumping, or jumping again, or going up stairs, try to keep your legs naturally bent. Tips: Knee pad exercise The following three exercises can effectively protect the knee joint and relieve knee pain. Choose two of them, exercise 2-3 times a week, and repeat these exercise steps 15 times each time to achieve the best exercise effect. 1. Leg muscle bending practice Take an elastic rubber band and tie it to the leg of a column or heavy furniture, with one end extending at the ankle of one foot. Stand facing the pillar, let the rubber band be in a tight state, slowly lift the leg backwards until the muscles at the back of the thigh feel slightly hot, then slowly put it down, and so on. Note: When lifting your legs, you should move your legs, not your hips. 2. Straight legs up This method exercises quadriceps femoris and hip flexors. Straighten your legs, lie flat face up, slowly lift one leg to straighten, silently count 15-20 seconds, and then slowly lower it. If you need to increase the amount of exercise, you can first add an object with a weight of 1 kg at the ankle, and then increase it in turn until it reaches 3.5 kg. 3. The back of the wall squats against the wall, and the heel is away from the wall 1 foot. Place a ball (basketball or football) between your knees, hold the ball, and slowly squat down along the wall until your knees and calves form a 90-degree right angle. Because the back is attached to the wall, supporting a part of the weight, and the knee is relatively less stressed, the human body feels comfortable with the intensity of exercise, silently counting for three seconds, and then slowly straightening out. Tip: Women's knee cartilage degenerates faster than men's. A study on "Arthritis and Rheumatism" conducted by Mu Chen University in Munich pointed out that even without any arthritis, women's knee cartilage is thinner than men's. The researchers compared the thickness of knee cartilage between 30 men and women aged 50-78 and 95 men and women aged 20-30, especially after the obvious pressure was applied to the knee joint. They found that the knee cartilage of older women was significantly thinner than that of younger women. Although the same is true for men, the degree of knee cartilage thinning in women is more serious than that in men. Every year, there are10 million female knee injuries in the United States. The reasons for the injuries are often: moving things, climbing stairs, squatting for a long time ... How to protect your knees in daily activities, and listen to experts' opinions.
