Traumatic synovitis of the knee joint

　　The external factors of traumatic synovitis of the knee joint are mainly mechanical injuries such as acute injury or chronic fatigue (including surgical injury), which are important pathogenic factors for traumatic synovitis. Acute traumatic synovitis is a disease with bleeding as the main symptom after injury.

　　Synovitis of the knee joint not only affects joint function but can also cause progressive organic damage to the joint. In severe cases, adhesions of the synovium can lead to the loss of joint function. Severe cases not only limit knee joint movement but also cause varying degrees of atrophy of the quadriceps femoris muscle, often accompanied by varying degrees of arthritis.

　　Traumatic synovitis of the knee joint is clinically divided into two types: traumatic inflammation and chronic fatigue inflammation. The specific clinical manifestations are described as follows.

　　1. If it is an acute injury, it is manifested as a knee joint hematoma. The joint hematoma usually occurs immediately after the injury or within 1 to 2 hours thereafter, with widespread ecchymosis on the knee and lower leg. During palpation, there is a sense of tension on the skin or the swollen area, and the patellar floating test is positive. There are often systemic symptoms, such as fever caused by ecchymosis, and the local area is relatively hot. This disease is often a complication of other injuries. It is necessary to examine carefully during clinical treatment to prevent missed diagnosis.

　　2. Chronic fatigue or traumatic synovitis of the knee joint, which is caused by improper treatment of acute synovitis, is more common in the elderly, those with damp constitution, or patients with genu varum, genu valgum, or other knee deformities, or those with osteoarthritis of the knee joint. The main complaints of patients are沉重不适 in the lower limbs and difficulty in extending and flexing the knees, but passive movement has no obvious obstacles, the pain is not severe, there is no redness or heat locally, and the knee joint function examination generally shows no obvious positive signs. A common phenomenon is the prominence and fullness of the patellar ligament at the patellar eye on both sides of the patella, which is soft to the touch, and even has a sacral sensation. If the joint effusion exceeds 10 milliliters, the patellar floating test is positive.

　　The primary prevention of traumatic synovitis of the knee joint is to prevent joint injury, and the specific preventive measures are described as follows.

　　1. Avoid excessive activity and fatigue of the knee joint, especially for those who engage in剧烈 lower limb exercises. Pay attention to the combination of work and rest to prevent tissue damage caused by overexertion.

　　2. When a knee joint fracture occurs, it is necessary to seek medical treatment in a timely manner and strive to achieve anatomical reduction of the fracture ends. If the reduction is not satisfactory, surgical treatment should be taken promptly.

　　3. Elderly people can appropriately supplement calcium, vitamin D, and other drugs closely related to bone metabolism and joint health. At the same time, they should engage in moderate physical exercise to slow down the aging and degenerative process of bone tissue.

　　The examination of knee joint traumatic synovitis includes physical examination and X-ray examination, the specific clinical manifestations are described as follows.

　　1. Physical Examination

　　Examination shows swelling and fullness on both sides of the patellar ligament at the knee eyes, palpation shows softness, and even has a sacral sensation. If the joint effusion exceeds 10 milliliters, the relief test is positive. The general examination of knee joint function usually does not show obvious positive signs.

　　2. X-ray Examination

　　X-ray examination can show joint囊swelling and synovial swelling, sometimes it can be seen that there is bone destruction and other conditions.

　　Patients with knee joint traumatic synovitis should eat high-protein and nutritious foods; eat foods rich in vitamins and minerals; eat high-calorie and easy-to-digest foods. Avoid eating greasy and difficult-to-digest foods; avoid eating fried, smoked, grilled, cold, and刺激性 foods; avoid eating high-salt and high-fat foods.

　　The knee joint traumatic synovitis should handle the relationship between activity and fixation correctly, and can also be treated with medication, the specific treatment methods are described as follows.

　　1. Fixation and Activity:Activity can stimulate synovial secretion and continue bleeding, but activity can also prevent muscle atrophy and joint adhesion. Therefore, the relationship between activity and fixation should be handled correctly, and patients should be guided to actively exercise in the制动 state, and to actively practice knee extension and flexion exercises after fixation is removed. It is forbidden to use passive and strong manual techniques for activity.

　　2. Drug Treatment:During the acute stage, the treatment should focus on removing blood stasis and promoting the formation of new tissue, taking Tao Hong Si Wu Decoction with 3g of Tianqi powder internally, and applying Xue You Zhi Tong plaster externally. During the chronic stage, there is retention of dampness and weakness of the muscles and tendons, the treatment should be to expel wind and dry dampness, strengthen the muscles and tendons, taking Qianghuo Shengshi Decoction with modifications or taking Jian Bu Zhuang Gu Wan internally, and applying Wan Ying plaster externally, or using Fengshu heat-retarding compress, or using the external washing formula for the limbs to be boiled and washed externally. If there is a strong cold evil in chronic patients, it is also possible to disperse cold, expel wind and dampness, and use Wu tou Decoction; if the wind evil is predominant, it is advisable to expel wind and dampness, reduce swelling and eliminate distension, using the Quan Bi Decoction.
