Self-prevention of osteoarthritis of the knee It is common to see patients in hospitals who squat and get up with one hand on the knee, one hand on the table, or even with the help of others to stand up, and it is very painful, which is usually osteoarthritis of the knee. This is what the people call a long bone spur in the knee. Osteoarthritis is a chronic joint disease in which the main changes are degenerative changes in the cartilage surfaces of the joints and secondary osteophytes. The main manifestations are joint pain and inflexibility. X-rays show narrowing of the joint space, dense subchondral bone, broken trabeculae, sclerosis and cystic changes. There is lip-like hyperplasia at the edge of the joint. In the later stage, the bone ends are deformed and the joint surface is uneven. The cartilage in the joint peels off and the bone fragments into the joint, forming intra-articular free bodies. Osteoarthritis, also known as degenerative arthritis, is not actually an inflammatory condition, but is primarily a degenerative condition that involves premature aging of the joints, particularly the articular cartilage. Osteoarthritis represents the aging of the joints and is therefore called age-related arthritis. The broader term osteoarthritis also includes other aseptic arthritic disorders. According to statistics, the incidence of osteoarthritis of the knee is increasing year by year, with 60% of people over the age of 50 suffering from the disease and about 80% of people over the age of 70 suffering from the disease. Previously, osteoarthritis of the knee was thought to be a disease specific to the elderly, but clinical evidence suggests that secondary osteoarthritis often occurs in younger people as well. This disease is predominantly painful in the early stages and painful plus dysfunctional in the later stages. However, if this disease is taken seriously, early exercise and prevention can slow or even halt its progression and reduce pain. Joint self-test Knee arthritis starts with no symptoms, but if the following occur, you should go to the hospital for examination: 1, squatting, turning, bouncing, going up and down stairs, standing up after sitting for a long time, pain appears or pain worsens, but not or not obvious at other times. 2. Knee stiffness in the morning, reduced after a little activity. 3.Knee joint flexion and extension will hear the “click, click, click” sound and ball friction. 4. Knee pain is worse after cold. 5.Joint deformation, can not get up from squatting, can not get up from squatting. Three causes of knee pain Osteoarthritis of the knee is one of the most common knee diseases. It is a degenerative phenomenon brought about by aging, resulting in low synovial fluid secretion, ligament and muscle strain, and wear and tear of the knee joint during long-term activities as if it were a grinding disk; it is also accelerated by external wind and cold, trauma, etc., which causes the cartilage to age and form bone spurs, stimulating and compressing the surrounding soft tissues and nerves, resulting in a series of symptoms. Performance Performance 1. Slow onset, mostly seen in middle-aged and elderly obese women, often with a history of exertion. 2. The 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 when going up and down stairs. 3. The knee joint activity is limited, or even limping. Very few patients may develop interlocking phenomenon or knee joint effusion. 4. 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. 5. Knee pain is a common complaint of patients with this disease. The early symptoms are pain when going up and down stairs, especially when going downstairs, unilaterally or bilaterally, and joint enlargement, mostly due to bony hypertrophy, or joint effusion. Synovial hypertrophy is rare. In severe cases, the knee is deformed. Four-step treatment method Squat body first stand upright, hands naturally down or crossed waist, feet with both knees facing forward, feet feet distance of about 10 cm. From the knee downward bending, a small half squat. To static squat stable, about 10 minutes -30 minutes squat. Do this once a day in the morning and once in the evening. This is a comprehensive exercise for the knee, can effectively improve the ability of both knees of the elderly, the middle-aged and elderly knee disease has a very good treatment and rehabilitation role. The elderly in the static squat, the back should be close to the wall or hands to hold on to tables and chairs, etc. to avoid falling. The body of the first taut straight standing, hands naturally down, feet knees facing forward, feet feet distance of about 10 cm. Knees are straight, joints do not move, tense the muscles on the front side of the thigh (quadriceps). Apply force for 6-10 seconds, rest for 10 seconds, then apply force for 6-10 seconds, rest for 10 seconds, and so on for 20-30 contraction exercises. 3-4 times a day. This progressive resistance training increases muscle strength. Patients who tie an elastic resistance band at the ankle joint against the force of active knee extension and gradually increase the resistance will gradually increase the strength of the quadriceps knee extension. The elderly should keep their backs against the wall or hold on to tables and chairs with both hands when doing thigh tensing exercises to avoid falling. Pinch by massaging the meridian points of the legs and feet, you can achieve the purpose of blood circulation. There are four main points: the inner knee eye point, the outer knee eye point, the commission point, and the yinggu point. The outer knee eye point is shaped like a calf’s nostrils, and the inner knee eye point is called the inner knee eye point. It is written in acupuncture books that it can treat knee pain and cold paralysis. The Guizhong point is one of the more important of the many points used to treat osteoarthrosis of the knee. It is located in the central part of the posterior side of the knee called the N fossa. It is described in the “Acupuncture and Moxibustion Zisheng Jing” as “dispersing cold and removing dampness, activating the meridians, and strengthening the waist and knees”. Therefore, treatment here can dissipate cold and dampness through the bladder meridian. The Yin Gu point is a joint of the Kidney meridian and is flush with the Wei Zhong point, on the inner side of the N fossa; Yin refers to the inner side, and Gu refers to the depression, where the essence of the Kidney meridian converges, like the granary of the Kidney meridian, providing logistical support for the Kidney meridian. Pressing this point can invigorate the qi of the kidney meridian and play a role in nourishing the kidneys and bones. Massage these 4 points above once a day for 5-6 minutes each time, with not too much force, to slightly feel sore and swollen. Soak with 30g of ginger, 30g of Zeilan, 30g of safflower, 30g of hyssop and 20g of trigon after 30 minutes of decoction, mix with water to about 40 degrees, put in a basin or bucket, soak both lower extremities and use a towel dipped in the soup to apply externally on the knees, 1-2 times a day for about 20 minutes each time. Ginger can cause the cold effect; Zeilan water and swelling to reduce friction in the joint; safflower blood circulation and pain relief, increase the local microcirculation of the knee joint; cow knee, trigon to disperse stasis and pass through the ligament, in order to cure the soreness and weakness of the disease. Life seven notes 1, pay attention to warmth and cold, best not to be poured by the rain in summer, and bring knee pads in winter. 2. Walk on level ground as much as possible, climb less or no hills, and when you have to go up and down stairs, it is better to hold the railing with your hands to reduce the pressure. 3, pay attention to walking and labor posture, avoid prolonged squatting, long standing, do not drag the leg walking and labor. 4, should wear thick, soft-soled flexible shoes, women should not wear high-heeled shoes. 5, both to avoid excessive exercise, but also appropriate functional exercise, swimming and walking is the best exercise; followed by sit-ups, push-ups, taut legs of the movement is also good. 6, obese people should lose weight. 7, diet should eat more food containing protein, calcium, collagen, such as: milk, dairy products, black fungus, fish and shrimp, cow’s trotters, etc. Conventional treatment 1, non-surgical treatment (conservative treatment) including physical therapy, drugs, injection therapy and Chinese herbal medicine treatment, etc. 2. Surgical treatment (1) Knee arthroscopic exploration and cleaning This is a new and safe technique for diagnosing and treating knee diseases, which makes patients suffer less pain and complications, and has the characteristics of fast recovery and significant curative effect. (2) Knee joint replacement is a surgical procedure to replace the damaged knee joint partially or completely with artificially made joint parts, which involves removing the worn and damaged joint surface and implanting an artificial joint, just like braces, to restore the normal smooth joint surface. This restores a normal joint surface and allows for normal joint movement.
