What are the symptoms of knee degeneration? How to prevent knee degeneration?

Knee degeneration is a relatively common chronic progressive arthropathy, also known as knee osteoarthritis, mainly due to the aging of cartilage on the articular surface of the knee joint, which causes the joint surface to be unsmooth, resulting in changes in the negative gravity line, and then causing degenerative changes in the joint and cartilage tissue.

According to incomplete data, about 55 years of age in the middle-aged and elderly population.

Sixty percent of people have this disease, because during the desperate period, the body's hormone secretion decreases, resulting in the atrophy and degeneration of the hyaline cartilage of the knee joint, and with the mild damage of the upper joint, it will form "rust spots", resulting in local necrosis of the cartilage. How can I prevent knee degeneration after 45?

1. Avoid long-term strenuous exercise: long-term, excessive, strenuous exercise and exercise are the main factors causing knee joint degeneration, excessive exercise increases the pressure on the joint surface, makes it more fatigued, and avoids long-term strenuous exercise. At the same time, attention should be paid to reducing the burden on the knee (eg:

Less squatting, stair climbing, stair climbing, local warmth, and gentle exercises).

2. Proper physical exercise: Do not engage in long-term intense exercise. Moderate exercise, especially joint movement, can increase the pressure in the joint cavity, promote the flow of joint fluid into the cartilage, and alleviate joint degeneration.

Men in their 40s can do some low-level exercises, such as running, and women should strengthen some strength exercises, which can alleviate osteoporosis and obesity. Men can do aerobic exercises such as brisk walking, swimming, cycling, etc., while women can swim and walk slowly.

3. Timely ** joint lesions: joint lesions have a good relationship with arthritis and intra-articular fractures.

4. Knee joint injury should be avoided: long-term cold and temperature changes will cause knee joint damage. Pay attention to keeping warm in summer, do a good job of keeping your knees warm in summer, and don't let the air conditioner and fan wind blow directly on your knees.

5. Weight loss: Obesity is the main factor leading to spinal and joint degenerative diseases. Obese women have 4 more cases of degenerative arthritis of the knee than the general population. Excess weight is a great load, which leads to wear and tear of the cartilage of the joints and uneven stress.

Therefore, it is necessary to carry out moderate ** for obese people. In daily life, you should pay attention to keeping warm, do not catch a cold, do not carry out any weight-bearing exercises, do not do any climbing exercises, and carry out appropriate exercises in time to avoid knee discomfort.

Knee joint degeneration will be manifested as pain in going up and down stairs, and the impact of not being able to do some heavy physical work; In daily life, you should pay attention to protect your knees, do not always go to the mountains for a long time, climb stairs or do heavy physical labor, and eat more calcium-containing foods.

These symptoms are immobility, painful sensations, and deformities. May lose the ability to walk. It is necessary to strengthen exercise, but also exercise, and to supplement more calcium, so as to prevent the occurrence of such diseases.

The knee joint is composed of cartilage and medial meniscus of the femur and tibia, the meniscus is commonly known as the cartilage pad, and every time the knee joint flexes and extends, the meniscus and all the cartilage surfaces involved have to be rubbed again, and over time, the cartilage pad wears out and degenerates.

Who is susceptible to knee osteoarthritis?

The knee joint is a very special joint, and people of different ages may have different problems, for example, young people may have knee strain, cruciate ligament tear, and meniscus injury due to excessive exercise or improper exercise mode; Middle-aged people may be overloaded with cartilage or overweight due to cartilage wear; Common problems in the elderly include degeneration, bone spurs, bone deformation, joint displacement, etc. Especially when the temperature drops, people with poor knee joints are even more miserable.

Make lifestyle changes to avoid wear and tear on your joints

1) As the saying goes: "If there is an injury, there must be cold", cold and dampness are also the main culprits of various knee joint diseases, so the knee joint must pay attention to the warmth of the knee joint when the knee joint is less sick; Wear knee pads if necessary to prevent your joints from getting cold, especially in summer. Pay attention to walking and working posture.

2) Avoid overworking the joints, minimize frequent climbing exercises, and try not to do squat exercises on the knee joints.

3) To lose weight, it is necessary to control the diet, increase exercise moderately, and scientifically reduce the load on the joints. Swimming and walking are the best exercises that do not increase the weight-bearing capacity of the knee joint, but also allow the muscles and ligaments around the knee joint to be exercised.

4) Limit salt: Don't think that eating too much salt will only affect blood pressure, too much sodium intake will also damage our joint health. Try to limit the amount of salt you eat to 5 to 6 grams per day.

5) Eat more foods with high calcium content, such as milk, eggs, soy products, vegetables and fruits, etc., and supplement calcium according to the doctor's instructions if necessary.

Standardize**, effective intervention in articular cartilage lesions

Joint PRP Specialist**: Repair of damaged joints

The patient has had pain in both knees for more than 20 years and has already been damaged, which can only be repaired with joint PRP specialist** technology. Osteoarthritis is mostly caused by degenerative changes in the joints, which cannot be relieved by pain relief alone. Chronic disease management in the later stage is an important step in anti-**.

What is PRP (platelet rich plasma): It is a platelet concentrate extracted from whole blood by centrifugation, containing a high concentration of platelets and white blood cells.

**Process: Extract 30L-50L of your own blood, then isolate and extract chondrocyte growth factor, and inject the growth factor into the damaged part, the main purpose of which is to promote the regeneration of human bone tissue and the repair of cartilage. Speeds up the healing process and restores joint mobility.

The knee joint is an important joint of people, when there is a problem with the knee joint, it will affect people's movements, and its symptoms are mostly manifested as redness, swelling and pain in the knee, pain in going up and down stairs, knee pain and discomfort when sitting up and walking, etc. There will also be patients showing swelling, popping, fluid accumulation, etc., if not timely, it will cause joint deformity, and even some patients with knee arthritis can not take care of themselves.

Degenerative knee arthritis is a more common type of disease in clinical practice, and it is more common in middle-aged and elderly patients

1. Walking: It is necessary to start from slow walking, that is, walking slowly, not fast, the general speed is controlled within 60 steps per minute, if walking too fast, the joint bone surface will be impacted, resulting in injury or aggravation. Generally, it is enough to exercise for an hour a day, and the exercise can be completed at one time or several times, depending on the patient's physical condition.

If you can continue to walk slowly for 3 months, the knee function will improve, and then gradually increase the pace;

2. Cycling: The quadriceps muscles can be exercised, because the range of motion of the knee joint is relatively limited, and the joint force is relatively weak, so as to reduce the chance of impact and wear on the joint surface. Cycling for about an hour a day can relieve knee pain and delay knee degeneration;

3. Jogging: If the symptoms are not serious, suitable for elderly patients who are allowed to do so, jogging is a good way to increase the flexibility of joint ligaments, but when jogging, you need to pay attention to the forefoot to land on the ground first, cushion local vibration, and prevent knee joint injury;

4. Swimming: Because of the buoyancy of water, it can relieve the pressure of gravity on the joints of the body and relax the muscles, so it is better for the body for patients to carry out swimming exercises appropriately.

How can I exercise if my knee is already uncomfortable or has degenerative arthritis? Patients with degenerative knee joints can do more light exercises, and it is not recommended to do deep weight-bearing exercises. It is recommended to do more light recreational exercises such as swimming, walking, slow walking, or exercising the thigh muscles, and do not do weight-bearing exercises such as climbing and squatting.

Prevent knee degeneration Do this exercise before bedtime.

Elderly people often have knees stuck, and walking is accompanied by pain, and it is difficult to even go up and down stairs, and I am afraid that the knee joint has degenerated. Experts recommend that doing more straight knee and leg raises every night before going to bed can strengthen the thigh muscles and gradually improve knee pain.

Knee degeneration is a common disease in middle-aged and elderly people

The knee joint supports the weight of the human body for many years, coupled with the accelerated wear and tear of excessive walking and exercise, knee joint degeneration is a common disease in middle-aged and elderly people. Lin Junfang, a physicist, pointed out that according to clinical observation, most of the patients with the degeneration of the closed wheel spike of the knee joint are elderly, complaining of knee pain and weakness, and then seeking medical treatment, such as electrotherapy, hyperthermia, etc., which can help relieve pain symptoms.

Avoid squatting and kneeling Go up and down the hill slowly

How to prevent knee degeneration? Lin Junfang, a physicist, emphasized that first of all, it is necessary to avoid injuring the knee joint, remind the middle-aged and elderly to avoid squatting, kneeling and other actions as much as possible, in addition, it is also necessary to reduce the frequency of climbing, downhill and downstairs, and it is best to slow down when going downhill and down stairs.

Straight knee leg raises strengthen thigh muscles

Lin Junfang's physicist recommends 2 straight knee and leg lift exercises, which can strengthen the thigh muscles through weight-bearing exercises, which can prevent knee joint degeneration. The first move, lie flat, straighten one knee with one foot, lift up 30 cm, stay for 10 to 20 seconds, 10 reps per round, a total of 3 times, and then change feet; In the second move, the body is seated, one knee is straight and parallel to the ground, stay for 10 to 20 seconds, 10 reps per round, a total of 3 times, and then change feet.
