Osteoarthrosis of the knee has become a common and frequent disease in the elderly population. According to the World Health Organization, the incidence of osteoarthrosis of the knee is 50% in people aged >60 years and 80% in people aged >75 years. Non-surgical treatment is generally preferred for osteoarthrosis of the knee. Among the non-operative treatments, people are most accustomed to the application of medications, while daily adjuvant rehabilitation is often neglected. Daily rehabilitation for osteoarthrosis of the knee should pay attention to the following aspects: 1. Improvement of the living environment: Patients with osteoarthrosis often have pain, swelling and functional limitations of the joints, so their living environment should be more convenient and comfortable compared to normal people. For example, the toilet in the living room should use a flush toilet instead of a full squatting type to prevent inconvenience caused by the inability to overflex the knee joint; grocery shopping and shopping around the residence should not be too far away, and transportation should be convenient to prevent excessive walking of the joints leading to aggravation of osteoarthritic symptoms, etc. 2, engage in more suitable types of work: osteoarthritis patients should engage in less walking, less joint flexion activities, joint load less work to reduce the stimulation of the diseased joint, to prevent the aggravation of osteoarthritis. 3, reasonable arrangements for daily life: patients with osteoarthrosis should not be overly active, but also not at all immobile. For example, before the disease to go to the cinema to walk 2000 meters in one breath can be completed, but after the disease, a breath to walk the joint may be discomfort, if divided into 3-4 sections to walk, each section of a break, you can achieve the purpose of not reducing the amount of activity, but also harmless to the joint. 4, quadriceps muscle strength training: quadriceps muscle is an important structure to maintain the stability of the knee joint, osteoarthrosis patients with quadriceps muscle more than obvious atrophy, resulting in a decline in the stability of the knee joint and the patellofemoral joint does not fit the groove movement, can be at the occurrence of osteoarthrosis and aggravation of the condition. Strengthening the quadriceps muscle can restore the stability of the knee joint, thereby reducing the symptoms of osteoarthrosis and increasing other therapeutic effects.
