What Are the Most Common Causes of Knee Pain and Swelling?

The knee is a body part of the human body and is located at the junction between the upper and lower legs. The main internal structure of the knee is the meniscus and four ligaments.

Knee knee pain

Usually in the middle point,

Self-treatment method: lying asleep, legs straight, healer standing sideways with thumbs

Sagittal midline of knee

Press the middle part. If it is the left leg, use your right hand, it is the right leg, with your left hand, the finger is up, and the force is vertically downward. Press once a day for more than ten minutes each time until it is good. The knee joint is a large and complex flexing joint of the human body. It is subject to large stresses, and its structure is stable and flexible. Knee pain often occurs, and this pain is often overlooked or arbitrarily considered to be arthritis and other conditions.

In fact, there are many reasons for knee pain. In daily life, most joint pain is not caused by trauma. Prolonged cooling of the joints and large temperature differences are the main causes of joint pain. Especially in autumn, when cold and warm are alternated, low temperature or huge temperature difference can cause muscle and blood vessel contraction, causing knee pain.

If you encounter this situation, you must first keep it as warm as possible. You can use hot compress. The second is to reduce the amount of exercise and let the joints rest. If the above methods do not improve knee pain, then go to the hospital for treatment and determine the cause of the disease.

There are several common injuries that can cause knee pain:

1. Fat pad strain Fat pad fills the gap in the front of the knee joint, and has the effect of strengthening joint stability and reducing friction. The cause of fat pad strain may be due to trauma or long-term friction, which may cause hyperemia, hypertrophy and inflammation of the fat pad, and adhesion with the patellar ligament, which restricts knee joint movement. This injury mostly occurs in people over 30 years old who often walk, climb or squat frequently. Patients may feel pain in the knee joint, which becomes worse when fully straightened, but joint movements are not restricted and symptoms are noticeable after exertion.

2. Meniscus injury Meniscus injury is a common injury of athletes. When the lower extremity bears weight, the foot is fixed, and the knee joint is slightly flexed, if the knee is excessively turned internally or externally (for example, during volleyball, Suddenly turning around to save the ball while defending), it may cause the meniscus to tear. Meniscus injuries will have a noticeable tear in the knee, followed by joint pain, limited mobility, and lameness in walking. The joints show swelling and slipping, and they bounce when the joints move.

3. Knee joint traumatic synovitis The knee joint synovium is one of the main structures that make up the knee joint. Synovial cells secrete synovial fluid, which can keep the articular cartilage surface smooth and increase the range of joint movement. Damage to the synovium due to trauma or excessive strain will cause a large amount of effusion and increase the pressure in the joint. If it is not removed in time, it will easily cause joint adhesion and affect normal activities. The patient will feel pain, swelling, tenderness in the knee joint, and friction and astringent sound of the synovial membrane. The most obvious feature of pain is that when the knee is actively straightened, especially when the knee is stretched with a certain amount of resistance, the pain in the lower part of the sacrum will be aggravated, and the pain will be significantly worsened during passive extreme flexion.

4. Knee osteoarthritis is more common in middle-aged and elderly people, and most of them are women. Overweight is the main cause of the disease. The knee joint will swell and pain, and sometimes there will be friction sounds in the moving joint. The knee may have varus deformities with medial pain.

5. Knee joint ligament damage The stability of the knee joint is relatively poor. If external force suddenly causes valgus or varus at this time, it may cause medial or lateral collateral ligament damage. Clinically, the medial collateral ligament injury accounts for the vast majority. Taking this kind of injury as an example, the patient will have a clear history of trauma, pain and tenderness on the inner side of the knee joint, and the pain will increase during passive abduction of the lower leg. Knee movements are restricted. The above five kinds of injuries that cause knee joint pain cannot be cured by daily health care alone.

Experts remind: If you have the above pain characteristics, you should ask the doctor to make a clear diagnosis as soon as possible to avoid delaying the best time for treatment.

Hydrocephalus

Symptoms

Synovitis is a common disease of professional athletes. Synovitis is a sterile inflammation disease. It is caused by multiple causes of abnormal synovial function and morphological changes in the joints, causing excessive synovial fluid production and absorption disorders, resulting in joint swelling, pain, and functional impairment. Limit, muscle atrophy and other major clinical manifestations of a disease. Among them, knee synovitis is the most common. The knee joint is the joint with the most synovium, the largest joint and the most complicated structure in the human body. Because the knee synovium is extensive, heavy and heavy, it is most vulnerable to injury. Therefore, knee synovitis is the most common in clinical practice. The synovium is mainly distributed around the joint, communicates with the joint cavity, secretes lubricating fluid to lubricate the joint, and is affected by various causes (such as osteogenesis, arthritis, joint tuberculosis, rheumatism and traumatic trauma, bone injury, intra-articular injury, etc.). Soft tissue injury, surgery, etc.) stimulate or directly stimulate synovial injury to produce an inflammatory response, and the synovial response to inflammation is secretion of exudate. If pain occurs, strictly speaking, as long as there is exudate in the joint, synovial inflammation is proved, which mainly shows joint congestion and swelling, pain, increased exudation, joint effusion, difficulty in squatting, and limited function.

Symptoms

How do I know if I have water on my knees. Floating test to determine whether joint effusion occurs when the knee joint is injured. There is about 5ml of fluid in the normal knee. When the effusion of the joint exceeds 50ml, the floater test is positive.

Inspection method: Straighten the knee joint of the affected leg, relax the quadriceps, the examiner squeezes the epicondyle with one hand to accumulate the joint fluid behind the metatarsal, and gently press the metatarsal with the index finger of the other hand. If there is a floating feeling, you can feel the metatarsal collision The impact sound of the femoral condyle; the loose pressure causes the sacrum to float again, which is positive, indicating that there is fluid in the joint. If you cannot confirm the diagnosis yourself, it is recommended that you go to the surgical hospital to review the diagnosis and treatment to prevent delay in treatment.

Knee hyperplasia

With the increase of age, the bones of the knee joint have been worn out for many years, and the surrounding ligaments have become loose, causing joint instability and causing lesions to cause bone hyperplasia in the corresponding parts. This proliferation is a phenomenon of human aging. After the age of 40, most people have bone hyperplasia, but the location and degree of hyperplasia are different, some are symptomatic and some are asymptomatic.

There are many causes of knee bone hyperplasia, such as increasing age, long-term fatigue or joint trauma, joint developmental deformity, etc. can lead to degenerative changes in the knee joint, affect the stability of the joint, and form bone spurs around the joint. Causes bone hyperplasia. ^[2]

Traditional Chinese medicine treatment can be roughly divided into two categories: one is internal treatment, that is, oral decoction, pills, powder, alcohol, etc .; the other is external treatment, that is, alcohol external tincture, fumigation, external application. Oral drugs are absorbed, digested, and decomposed by the stomach and intestines, and finally can be delivered to the local area through blood circulation. The entire process needs to pass through layers of barriers to reach the lesion. However, the effectiveness of the drug is very low, so the effect is extremely slow and low. Effective, and clinical application of these methods can only relieve pain symptoms, functional rehabilitation is irreversible, and bone repair is impossible to talk about. In addition, oral medicine has great damage to liver, kidney and gastrointestinal tract. Therefore, it is better to choose a topical drug for drug introduction. The drug penetrates from the outer skin and penetrates into the bone without any side effects.

The key to treating bone hyperplasia is not to eliminate bone hyperplasia, but to eliminate aseptic inflammation around bone hyperplasia. If there is pain, you can use anti-inflammatory analgesics or closed treatment for symptomatic treatment, or use heat compresses, physical therapy, massage and traction to promote blood circulation, relax local muscles and relieve pain, or use a small needle knife to reduce nerve compression. At present, domestic and international patients are generally recommended to use GZ-IIIC drugs to introduce hyperthermia in daily home nursing rehabilitation therapy. It uses low-frequency modulation of intermediate-frequency pulse current and drug guidance to combine intermediate-frequency electricity and drug introduction. Together, to achieve the therapeutic effect on the disease, it can be used alone or in combination with external medicines. When combined with external medicines, it can double the effect of the medicines in addition to its own effects. Clinically proven to have exact efficacy. It is very suitable for the use of knee bone hyperplasia, simple and easy to understand, safe to use, and easy to carry, especially suitable for clinic and home use.

After the elderly have noticed significant bone hyperplasia, moderate exercise should still be performed, but long-term vigorous exercise should be avoided, because long-term vigorous exercise can make the bones and surrounding soft tissues unevenly stressed, overloaded, and increase pain. At the same time pay attention to cold and warm.
