Having osteoarthritis is to walk as little as possible. Osteoarthritis is caused by the destruction of joint cartilage and uneven joint surfaces. Long-term walking will lead to more serious wear and tear of the joints, which will aggravate the condition and pain symptoms of patients with osteoarthritis, therefore, patients with osteoarthritis should try to walk as little as possible. In severe cases, canes, crutches, walkers, etc. can be used when walking to reduce the weight-bearing of the knee joint and reduce wear and tear. However, patients with osteoarthritis should not stay in bed for a long time, and should maintain a moderate amount of activity. They can choose swimming, bicycling and other ways to exercise, so that the knee joints can be properly flexed and extended to maintain the mobility of the knee joints. Osteoarthritis patients can also promote local blood circulation and reduce local inflammatory reaction through local hot compresses and physiotherapy. Osteoarthritis patients should go to the hospital in time, under the guidance of the doctor for regular treatment.
