Exercising the muscles of the legs not only relieves joint pain, but also prevents the progression of the disease. Do not assume that the only way to protect the diseased knee joint is to rest and not be active. According to studies, swimming and walking are the best exercises for patients with osteoarthrosis of the knee, which do not increase the weight on the knee joint but also allow the muscles and ligaments around the knee joint to be exercised. Secondly, supine leg lifts and empty pedal bicycles are the best exercises for patients. 8, active treatment treatment, once the knee joint pain, to actively treat, take heat, physical therapy and other simple therapy, if conservative treatment does not work and affect walking and daily life, should go to a large hospital with arthroscopic technology to clean up the knee joint, serious osteoarthrosis patients with poor arthroscopic treatment can choose arthroplasty to restore joint function and maintain a good quality of life. 9, maintain the appropriate weight to prevent obesity, increase the burden on the lower limb joints, once the weight is overweight, to actively lose weight, pay attention to adjust the diet, control weight. 10, reasonable diet diet, should eat more protein, calcium, collagen, isoflavones, such as milk and dairy products, beans and soy products, fish and shrimp, kelp, black fungus, chicken feet, pig’s feet, lamb leg, tendons, etc., these can supplement protein, calcium, prevent osteoporosis, but also nutritional cartilage and joint fluid, but also supplement estrogen, so that the bones and joints better calcium metabolism, reduce the symptoms of arthritis. Tip: In any knee disease, the first thing that happens is the atrophy of the quadriceps muscle (the muscle located in front of the thigh). The atrophy of this muscle will make the knee joint lose protection and become unstable, which can not only aggravate the symptoms, but also be detrimental to the rehabilitation of the knee joint, so for most diseases of the knee joint, it is important to encourage the exercise of the quadriceps muscle. The exercises strengthen the stability of the knee joint and improve local blood flow and metabolism, thus relieving pain, improving function and promoting recovery.
