What are the three possible causes of knee pain?

The knee joint is the most complex joint in the human body, with a large articular surface, more ligaments, and large load and superficial surface are its anatomical characteristics. There are several causes of knee pain:

1. Pediatric knee pain: it may be growing pain.

Another reason is that the epiphysis of the tibial tuberosity of the lower leg can also cause knee pain;

2. Patellomalacia.

May occur in young adults or old age;

3. Degenerative arthritis of the knee joint: it mainly occurs in middle-aged and elderly people and there are more female patients;

4. Meniscus injury of knee joint: it can cause knee pain;

5. Knee joint suppuration** infection: it can also cause knee pain;

6. Knee synovitis.

Bursitis, etc.: can cause knee pain;

7. Rheumatoid arthritis.

Knee pain can also be caused by knee involvement.

Knee pain can be caused by one disease or multiple conditions.

If the patient finds that the knee joint pain may be in the following aspects, the first time it is seen in the knee joint trauma, especially the trauma, the subsequent damage to the ligaments and joint capsule around the knee joint and the internal cartilage and bone damage will cause the swelling of the knee joint. Second, it is seen in the metamorphosis of the knee joint. Patients with osteoarthritis are more common in middle-aged and elderly people and those who work in manual labor, resulting in swelling and pain in the knee joint.

The third is that meniscus injuries seen in the knee joint can also cause symptoms of pain inside the knee joint, especially when squatting up and down stairs.

1.Arthritis.

When there is osteoarthritis and rheumatoid arthritis in the knee joint, it will cause knee pain and stiffness. Osteoarthritis mainly occurs in the elderly, and is related to osteoporosis, knee wear, old age and frailty; Rheumatoid arthritis is related to streptococcal infection, and can be accompanied by knee pain and swelling, joint deformity, mobility disorders, etc.

2.Synovitis.

The synovium is an auxiliary structure in the joint, and various reasons cause intra-articular synovial inflammation, which will cause swelling of the knee joint, local fever, tenderness and other sensations, which are related to long-term knee joint overactivity, knee joint strain, cold and other factors.

3.Soft tissue injuries.

The soft tissues around and inside the knee joint, such as periarticular ligaments, intra-articular ligaments, tendons, meniscus, etc., especially medial meniscus lacerations, usually the knee area will be stiff and regretful, swollen, painful, and snapping, and the knee joint can not move and stretch normally.

If knee pain occurs, it is necessary to treat the primary **symptom**, and you should go to the hospital as soon as possible for examination and diagnosis**. And you should pay attention to protecting your knees, reduce strenuous exercise, and take calcium tablets and glucosamine orally every day to prevent knee pain.

Due to trauma or long-term exertion, weight-bearing, and walking, the articular cartilage has degenerated.

There are many causes of knee pain. In everyday life, most joint pain is not caused by trauma. Prolonged exposure to cold joints and huge temperature differences are the main causes of joint pain.

Especially in autumn, when the temperature alternates, low temperatures or large temperature differences can cause muscles and blood vessels to constrict, causing knee pain.

Extended Materials. There are several common injuries that can cause knee pain:

1.Fat pad strainFat pads fill the gap in the front of the knee joint, which has the effect of strengthening joint stability and reducing friction. Fat pad strain may be caused by trauma or long-term friction that causes hyperemia, hypertrophy, and inflammation of the fat pad, which adhesions to the patellar ligament, thus limiting knee mobility.

This type of injury is more common in people over the age of 30 who walk frequently, climb mountains, or squat frequently. Patients will feel pain in the knee joint, which is worse when fully extended, but the joint movement is not restricted, and the symptoms are obvious after exertion.

2.Meniscus InjuryMeniscus injury is a common injury in athletes, and it can be caused by sudden excessive internal or external rotation of the knee when the lower limbs are weight-bearing, the foot is immobilized, and the knee is slightly flexed. Meniscus injuries can cause a significant tear in the knee, followed by joint pain, limited movement, and limp walking.

The joints show a feeling of swelling and slipping, and there is a snapping when the joints move.

3.Traumatic synovitis of the knee joint The synovium of the knee joint is one of the main structures that make up the knee joint. Synovial fluid secretes synovial fluid, which keeps the cartilage surface of the joint smooth and increases the range of motion of the joint.

Damage to the synovium due to trauma or overstrain and other factors will produce a large amount of fluid accumulation, which will increase the pressure in the joint, and if it is not eliminated in time, it is easy to cause joint adhesion and affect normal activities. Patients may experience pain, swelling, tenderness, and a grinding sound of the synovium in the knee. The most obvious feature of pain is that the pain in the lower part of the patella is exacerbated when the knee joint is actively and extremely straightened, especially when the knee extension exercise is done with some resistance, and the pain is also significantly worse when the knee is actively and extremely flexed.

The first reason is leg cramps.

This is rare, and general leg cramps do not cause knee pain, and if they cause pain, it is also post-knee pain. The main reason is that the muscles are too tight during cramps, and the muscles are too stiff because they don't exercise at any time, and if they cramp at this time, the knee is 100% painful. Moreover, not only can you have knee pain if you don't exercise regularly, but if you overuse your leg muscles, such as exercising too much, it can also cause cancer-causing pain.

The second reason is pregnancy.

Needless to say, this condition generally occurs in pregnant women. The main reason is that once a pregnant woman is pregnant, she rarely moves most of the time, and because of the increase in pregnancy weight, the pressure on the knee joint increases greatly, which will cause knee pain over time.

The third reason is osteoarthritis.

Osteoarthritis is mainly caused by the wear and tear of the articular cartilage, so this condition can easily lead to knee pain. Also, because of arthritis, it is not only the knee that is painful, but also the area around the knee.

The fourth reason is sports wear.

This condition is generally seen in people who are running, and it is also cartilage wear. However, unlike others, if you run too much, the cartilage in your knees can easily be worn away! Once it is gone, then the pain is doubled.

The fifth cause, deep vein thrombosis.

The condition can also cause knee pain, but it is generally rare. The main causes are obesity, old age, and smoking. Especially if you are sedentary, the probability of developing deep vein thrombosis is greatly increased.

Extended Information] How to Effectively Relieve Knee Pain:

Clause. 1. Exercise moderately. Many people think that when they have knee pain, they should lie still or rest in order to protect their knee joints, which is actually very wrong.

Because if you do this, the development of muscles will be worse, which is not conducive to the protection of bones and joints, and will worsen the pain of the knee joint. But don't do strenuous exercise, just take a walk.

Clause. 2. Appropriate rest and treatment. Although it is necessary to exercise properly, proper rest is also indispensable, and the specific reasons are needless to say.

Clause. 3. Rational use of cold and hot compresses. If you feel knee pain, you can reduce the pain by applying a cold compress to your knee within 48 to 72 hours. Of course, wetting a towel with hot water and applying it to your knees can also have a good effect.

I really can't alleviate it, so I can only see a doctor.

Knee pain is common for several reasons:

1.Due to trauma or long-term exertion, weight-bearing, and walking, the articular cartilage has degeneration and defects, and at the same time, the synovial fluid secreted by the articular cartilage will also be reduced, which will lead to the symptoms of knee pain.

2.In patients with rheumatoid arthritis, pain in both knee joints occurs at the same time in the early stages, especially in the morning, and after a period of activity, they feel slightly better. In this case, the patient also needs to undergo relevant tests as soon as possible.

Extended information] 1. Joints are a form of connection between bones. The connection between bones is called a bone junction. Bone connections are further divided into direct connections and indirect connections, and joints are a form of indirect connection.

Generally, it is composed of three parts: articular surface, articular capsule and articular cavity. The articular surface is the contact surface of two or more adjacent bones, one is slightly convex and is called the joint head, and the other is slightly concave and is called the joint fossa. The articular surface is covered with a smooth layer of cartilage that reduces friction during exercise, and the cartilage is elastic and also slows down vibrations and shocks during exercise.

The joint capsule is a tough connective tissue that holds two adjacent bones together. The outer layer of the joint capsule is a fibrous layer, and the inner layer is a synovial layer, which secretes synovial fluid and reduces friction during exercise. The joint cavity is a narrow space between the articular cartilage and the joint capsule, which normally contains only a small amount of synovial fluid.

2. According to the nature and activity of the connecting tissue, the joints can be divided into three categories: immovable joints, semi-joints and movable joints. Immovable joint: The two bones are connected by connective tissue without any gap in between, also known as non-lacunic connection.

For example, the ligamentous union between the forearm bone and the lower leg bone, the cartilage integration between the vertebrae, and the bony union between the ischia, pubic and patella. Movable joint: a connection with a lacunar space in the connecting tissue between adjacent bones, also known as a lacunar bone connection, usually called a joint.

Most of the bone joints in the human body belong to this type, and there are more than 200 in total, such as shoulder joints, elbow joints, wrist joints, hip joints, knee joints, ankle joints, etc. They are the pivots (i.e., fulcrums or pivots) of bone rotation. Half Joints:

It is a transitional connection between moving and non-moving joints. It is characterized by a direct connection between the two bones by cartilage tissue, and there are crack-like cavities in the cartilage, such as the pubic symphysis.

3. In the future process of osteoarthritis, we should first change the concept of patients and doctors, that is, the preferred method of osteoarthritis is not medicine, but the correct way of life and health care. Non-drug ** is the most basic ** method of osteoarthritis, if people pay attention to the relevant health education, it has a good effect on reducing pain, reducing the number of medical visits, improving the quality of life, and maintaining joint function, drugs are not the best method, through patients to change their bad habits, carry out appropriate physical exercise, physical **, weight loss, enhance muscle strength, help reduce the patient's symptoms, delay joint degeneration, The use of anti-inflammatory analgesics when pain occurs at rest or during daily activities can help reduce pain and improve quality of life.
