Knee pain is one of the most common symptoms in orthopedic clinics. It can cause slight inconvenience in life, and it can cause joint movement disorders and even disability. In this regard, Yue Bing, chief physician of the Department of Bone and Joint Surgery of Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine, cautioned that the cause of knee pain is more complicated. Once knee pain occurs, don’t panic, seek medical advice, and find out the cause of knee pain. Targeted treatment and rehabilitation measures can be used to control the disease and relieve pain. Specific treatment and rehabilitation measures are introduced as follows:
Because of the damage caused by exercise, the most common are synovitis, meniscus injury and knee ligament injury.
Common causes of synovitis are excessive exercise or knee sprains, synovial tissue congestion and edema, secondary aseptic inflammation, which causes knee pain, often accompanied by joint effusion. Synovitis can lead to discomfort or pain in the knee joint. The treatment is mainly through oral non-steroidal anti-inflammatory drugs, brake rest and local hot compress therapy. After the inflammation subsides, the knee pain will relieve itself.
Acute injury to the meniscus can also cause knee pain, which is manifested by severe pain and swelling of the knee joint after injury, and the knee joint cannot be stretched and bent. If the treatment is delayed or treated improperly, the meniscus injury will be transferred to the chronic phase, and the “joint interlocking” phenomenon in which the joint cannot be straightened suddenly appears. It is recommended to perform meniscalectomy or repair through arthroscopy as soon as possible.
The ligament of the knee joint is more complicated, and the knee ligament injury can cause very severe knee pain, accompanied by swelling, joint movement and tenderness. Mild and partial tears of the ligament can be treated conservatively, and complete fracture requires reconstruction by arthroscopic minimally invasive surgery.
Osteoarthritis is a common disease in middle-aged and elderly people. It is characterized by articular cartilage degeneration and subchondral bone hyperplasia. Patients may experience knee pain, effusion, swelling, stiffness, deformity and other symptoms, and it is difficult to walk and climb stairs. , affecting normal life. In addition, the painful side of the leg due to the lack of strength, and the transfer of body weight to the contralateral leg, will lead to two consequences: the affected side of the thigh muscle disuse atrophy, the thighs become thin; the opposite side of the normal leg due to excessive weight bearing, The joint wear is also aggravated so that the pain occurs between the two legs. The effect of conservative treatment is poor, and it can only play a temporary role in relieving pain. Patients with severe symptoms, obvious deformity, and severe joint destruction need surgery, and can relieve knee pain symptoms, correct joint deformities, and restore joint function.
Common rheumatoid arthritis, gouty arthritis, and infectious arthritis.
Rheumatoid arthritis causes synovial inflammation and secondary destruction of the joints, and knee pain often coexists with joint deformities and dysmotility. Patients with severe medical conditions and difficult to control medical treatment are treated with arthroscopic keratectomy and artificial joint replacement.
Acute exacerbation of gouty arthritis can also cause severe pain and swelling of the knee joint, which can be accompanied by general manifestations such as fever. Patients can take non-steroidal anti-inflammatory drugs, uric acid metabolism drugs and glucocorticoids. For severe joint damage, obvious joint deformity, and limited joint function, surgery is needed to control disease progression, correct deformity, and improve. Joint function.
The knee pain caused by infectious arthritis is more serious, accompanied by joint swelling and heat pain. In severe cases, it may be accompanied by systemic symptoms such as chills and high fever. Treatment should use a highly targeted antibiotic to control infection; for severe joint damage, after the infection is completely eliminated, joint replacement surgery is needed to restore joint function.
Director Yue Bing introduced that functional exercise has a positive effect in the treatment of knee arthritis. By exercising the leg muscles, knee pain can be significantly alleviated. The pain period is mainly the exercise method of raising the straight leg and resting on the wall. After the pain is relieved, you can choose swimming, cycling, walking and other exercises with lighter weight. The following simple small movements, combined with regular hospital treatment, practice for a little while every day, can effectively improve knee pain.
Back against the wall, visually in front, feet apart, shoulder width. The body slowly squats down, with the thighs and the horizontal plane less than 45 degrees for 3 minutes. 5 groups per day.
Knee straight side lift leg
The patient was in the lateral position, the leg was stretched straight, the hip joint was abducted, and the extension was 10 to 20 degrees. The patient’s leg was kept above the water level, and after 10 seconds, it slowly fell. 10 per group, 5 groups per day.
Sitting up straight
The patient is seated, hands are supported, the ankle joint and the thigh are stretched straight, slowly lifted, and lifted to a height of about 15 cm from the bed surface (horizontal plane) for 10 seconds, then slowly fall and then lifted up. 5 times per group, 5 groups per day.
Double knee clamping
The patient lies flat, the knee flexes, and is 20 cm away from the bed surface (horizontal plane). The ball is clamped on both knees and squeezed to the inside. After 5 seconds, relax for 2 seconds and then apply force. 1 group per day, 30 times in each group.
