Osteoarthritis of the knee is a chronic osteoarthritic disorder caused by degeneration and osteophytes of the knee cartilage, also known as osteoarthritis of the knee, degenerative arthritis and osteoarthrosis. The disease occurs mostly in middle-aged and elderly people, but can also occur in young people; it can develop unilaterally or bilaterally, and is more common in older women. Osteoarthritis of the knee joint develops slowly, mostly in middle-aged and elderly obese women, often with a history of exertion; pain in the knee joint increases with activity, characterized by paroxysmal pain at first, then persistent pain, worse with exertion and at night, and obvious pain going up and down stairs; limited movement of the knee joint, or even limping. Very few patients may develop interlocking phenomenon or knee joint effusion. There may be popping and grinding sounds when the joint moves, and some patients have swollen joints, and joint deformity can be seen over time. Conservative treatment of osteoarthritis of the knee: 1. Lower limb muscle exercise: mainly refers to the exercise of the quadriceps muscle group: the patient lies flat, straighten the lower limb, platform the affected limb to 45 degrees for 3-5 seconds, continue to do 20 times, this will increase the strength of the quadriceps muscle to achieve the purpose of protecting the knee joint. Balance exercises in the water or in the pool, refers to the water at waist level, walking, pay attention to the slow walking, which can reduce the weight of the lower limb joints, while exercising the balance of the whole body, mainly to achieve the premise of reducing the weight, increase muscle strength, improve balance, slow the progress of arthritis of the knee. 2, weight loss: weight loss is an important part of the functional exercise of the knee, older knee arthritis, often accompanied by weight gain, slow movement, weight loss becomes more difficult, the increase in weight, greatly increasing the weight of the knee joint, so that the functional exercise and pain relief is not easy, how to improve it, develop a detailed weight loss plan, eat less at night, increase the weight of low weight-bearing exercise, reduce weight. 3, oral medication: oral aminoglycosides, including glucosamine sulfate and other raw materials for the synthesis of cartilage, improve the state of the cartilage in the knee joint, not effective for patients with advanced knee osteoarthritis. Oral non-steroidal anti-inflammatory drugs, mentioned non-steroidal anti-inflammatory drugs, people often confused with antibiotics, pay attention to the emergence of degenerative arthritis, synovial inflammatory congestion, edema, resulting in joint pain, restricted movement, this non-antibiotic non-steroidal anti-inflammatory drugs is very effective, for advanced degenerative arthritis, also effective, pay attention to the complications of such drugs, such as digestive and cardiovascular system Complications, to be used under medical supervision. Drug example: diclofenac sodium 4, intra-articular injection drugs: early degenerative arthritis patients, you can intra-articular injection of hormones as well as sodium vitreous acid, improve the lubricating properties of the joint, some patients effective, note that such treatment measures should pay special attention to the aseptic principle of injection operations to avoid the emergence of joint infection; the author is not a supporter of this treatment method.
