What causes knee pain_What is the discomfort in the knee? What is the frequent pain in the knee? What’s wrong with my knee? What is wrong with the knee joint if it is not stiff and cannot be twisted? The knee joint consists of the lower end of the femur, the upper end of the tibia and the patella, which is the largest and most complex joint in the human body and belongs to the talocrural joint. The patella meets the patellar surface of the femur, and the medial and lateral condyles of the femur oppose the medial and lateral condyles of the tibia, respectively. Problems with any part of the knee joint can cause knee pain, and many knee disorders have overlapping symptoms that can be difficult to identify based on symptoms alone without the help of clinical examination and ancillary tests. What are the causes of abnormal knee joints? The following is a summary of the diseases corresponding to the 6 knee abnormalities. Here, for reference only, if a definitive diagnosis is to be made, it will of course have to be done in a doctor’s office. Details a frequent pain in the knee The main symptoms are: pain and swelling in the front and side of the knee; stiffness in the early morning that can last more than 30 minutes; pain after regular use of the knee; knee discomfort usually intensifies at night; pain in extreme cases walking or standing; permanent bending of the knee. Possible causes: Osteoarthritis. The cause is the continuous wear and tear of the joint cartilage, which hardens and thins, leading to inflammation. Detail two discomfort in the knee The main symptoms are: discomfort on the inside of the knee; pain is aggravated when climbing stairs; it hurts when touched by hand and has a warm sensation, and may have swelling. Possible causes: prepatellar bursitis. There are many small fluid sacs between the bone and tendons and ligaments. If the fluid sacs inside the knee experience trauma or overuse, the area can become swollen and inflamed. The main symptoms are: stabbing pain in the middle of the knee, increased pain when twisting from side to side; the knee is “locked” and cannot be bent or straightened. Possible cause: Meniscus tear. The meniscus is two crescent-shaped fibrocartilage located on the medial and lateral surfaces of the tibia, which acts as a shock absorber and cushion. When the meniscus is torn, small fragments can squeeze into the joint to induce inflammation. The main symptoms are: swelling of the knee, like a balloon that is not full of air; redness of the skin, but the pain comes from the inside of the knee and lower leg; the knee cannot move and is “stuck”. Possible causes: The swelling is caused by the accumulation of joint fluid, and if there is arthritis, the symptoms will worsen. The main symptoms are: severe pain that comes on within a few hours; redness of the skin and a shiny white lump under the skin; a very hot and stiff joint; symptoms that last 3-10 days and come on at night; the big toe may also be affected. Possible causes: Gout. This is the most common form of arthritis, usually caused by the accumulation of uric acid in the joints to induce inflammation. The disease has a genetic predisposition, but overweight and alcohol abuse increase the risk. Sardines and beans contain high levels of purines, which can aggravate gout symptoms. Detail six knee can not jump The main symptoms are: severe pain on the back and lower side of the kneecap when walking or running; sometimes the pain is so frequent that sleep is difficult. Possible causes: tendonitis, caused by patellar ligament injury. The tendons are weak and prone to develop in the elderly. Athletes and dancers often use the knee area and are at higher risk of developing the disease. Being overweight and having asymmetrical leg bones can also aggravate the condition. The most common condition of the knee is knee osteoarthritis, which is caused by inflammation and injury to one or more compartments of the knee joint. Depending on the cause, arthritis can be divided into different types. You have one or more risk factors for developing arthritis, consult your doctor about preventive measures to take. Weight loss Although many people find it difficult to lose weight, this may be one of the most important treatments for arthritis. Reducing the weight on your knees can reduce the risk of developing osteoarthritis by reducing joint loading and damage. Change your exercise routine Certain exercises may have to be limited, and learning new ways to exercise can help prevent or reduce the damage caused by arthritis. For patients with knee problems, water sports are an excellent choice. Using a cane or crutches on the opposite hand of the affected knee can help reduce the load on the joint.
