Why do older people often have knee pain?
1. Osteoarthritis of the knee joint
This condition is mostly seen in middle-aged and elderly people, mostly women. Overweight loading is the main cause of the disease. The knee joint will be swollen and painful, and sometimes there will be friction sounds when moving the joint. The knee may have an inversion deformity with medial pain.
2. Meniscus Injury
Meniscus injury is a common injury in athletes. When the lower extremity is weighted, the foot is fixed, and the knee is slightly flexed, a sudden excessive internal rotation and knee extension or external rotation and knee extension (for example, in volleyball, the player suddenly turns and fishes to save the ball while defending) may cause a meniscus tear. A meniscal injury can be characterized by a distinct tearing sensation in the knee, followed by joint pain, limited motion, and a walking limp. The joint exhibits swelling and slippage and pops when the joint is moved. Minimally invasive arthroscopic surgery is usually required for treatment.
3. Knee ligament injury
The stability of the knee joint is relatively poor when it is slightly flexed, and if sudden external force causes valgus or valgus at this time, it may cause medial or lateral collateral ligament injury. Medial collateral ligament injuries account for the majority of clinical cases. To this injury, for example, the patient will have a clear history of trauma.
4, improper exercise
Some elderly people like to hike, but if they do not prepare for the activity or exercise too much, it can also cause joint pain. Especially people who suffer from synovitis or osteoarthritis are more likely to cause joint disease attacks or aggravation. In mountain climbing, when descending a mountain, the weight of the whole body is put on one knee joint and the pressure on the knee joint is several times higher than when standing normally. The same situation occurs when people go up and down stairs.
5. Fat pad strain
The fat pad fills the gap at the front of the knee joint and has the effect of strengthening the joint stability and reducing friction. The cause of fat pad strain may be due to trauma or long-term friction that causes fat pad congestion, hypertrophy and inflammation, and adhesions with the patellar ligament, thus limiting knee joint movement. This injury occurs in people over the age of thirty who walk, hike or squat frequently. Patients may feel pain in the knee joint, which is worse when fully extended, but there is no restriction of joint movement. The symptoms are obvious after exertion.
6. Traumatic synovitis of the knee joint
Damage to the synovium due to factors such as trauma or overexertion will produce a large amount of fluid, which will increase the pressure in the joint. Patients will feel pain, swelling, pressure and pain in the knee joint, and the synovial membrane has a frictional and astringent sound.
7. Bad walking habits
For example, wearing unsuitable shoes or walking long distances in slippers or high heels can put the knee joint in an abnormal state of stress for a long time, causing chronic damage to the knee joint and knee pain.
What is arthritis?
Arthritis is a common chronic disease, commonly known as osteoarthritis and rheumatoid arthritis, and the number of people with arthritis in China is estimated to be more than 100 million, and is increasing. It is mainly characterized by joint redness, swelling, heat, pain and functional arthritis joint changes dysfunction. Patients with arthritis tend to have stiff and painful joints and have a natural tendency to reduce their activities to less, which can lead to stiffer and more painful joints. For this reason, arthritis should be taken very seriously. Arthritis can be classified according to its cause: rheumatic, rheumatoid, traumatic, osteoarthritis and septic arthritis. The details are as follows.
1, rheumatoid arthritis.
2, rheumatoid arthritis.
3, traumatic arthritis.
4, osteoarthritis.
5, septic arthritis.
What activities in daily life can cause knee pain in the elderly?
1, kneeling on the floor:, the pressure of the patella will be pressed on the femur, equal to the cartilage between the two bones directly to the ground, a long time, some knees can not straighten, can not get up. If you have to kneel to rub, you can consider a cushion under the knee, and kneeling time can not be too long, it is best to take a break every 10-20 minutes to maintain blood circulation, nourishing joint cartilage.
2, frequent climbing: when climbing, the knee joint bends in a bent state, will bear the weight of the whole body. Especially in the downhill, down the stairs, the body will lean forward, but the body will also consciously maintain balance and lean back. The two forces are concentrated in the knee joint, which will cause the knee joint to be subjected to a large impulse. At this point, the gravitational force on the knee joint is almost 7-8 times its own weight. It is best to bring crutches when descending to disperse the gravity. Slow down as much as possible, use the palms of your feet on the ground, do not make the palms of your feet violently touch the ground.
3, taijiquan: the elderly like to play taijiquan, taijiquan will often squatting horse stance, which is the same as climbing and jumping rope, easy to cause joint damage, the elderly due to age, the body secretes the amount of lubricating fluid in reducing, it is easier to knee pain, so the elderly should play taiji less squatting horse stance.
4, housewives dry housework: the amount of labor is not much though. But standing for a long time is easy to develop joint pain. Grocery shopping, excessive weight bearing.
Knee pain is more exercise is good or less exercise is good?
For this issue, many people have such misconceptions.
Myth 1: Knee arthritis should be more exercise: playing Tai Chi, climbing mountains, climbing stairs, many people believe that as long as diligent exercise, the function of the diseased parts can be restored, the results often make joint damage more serious. The cartilage and meniscus of the knee joint are the most vulnerable parts of the body when exercising, often leading to knee osteoarthritis.
Myth 2: You can’t move with knee disease: Contrary to some people’s belief that knee arthritis requires more exercise, many patients believe that they need to rest and recuperate from knee disease and remember not to exercise. This view is also biased, as long-term immobility of the joint can lead to malnutrition and premature degeneration of the cartilage. Therefore, the joints and ligaments need to be moved regularly, otherwise they tend to stiffen and age.
The right way is: the best exercise program is swimming, which can ensure the minimum load on the joints, but also exercise muscle strength. Usually doing extension and flexion exercises at home by yourself can also be of great help.
Cycling is an excellent form of exercise for the treatment and prevention of osteoarthritis. However, you should pay attention to the height of the seat, so that you can sit on the seat with your feet in the pedals and your legs straight or slightly bent.
How to protect the knee joint?
1. Diet structure, pay attention to the appropriate amount of calcium. Learn to eat scientifically and pay attention to calcium intake. Daily meals must be a variety of food appropriate mix to meet the body’s needs for a variety of nutrients. The nutrients provided by each type of food are not the same, and no one food can supply all the nutrients needed by the body. In addition, middle-aged and elderly people should pay attention to eating more calcium-containing foods in their diets, such as milk and soy products, which are rich in calcium and have a high utilization rate, and should be supplemented. Shrimp skin, sesame paste, kelp, walnuts, melon seeds, potatoes, etc. can increase calcium intake.
2, prevention and control of osteoporosis. Prevention of joint disease should pay attention to the health of the bones. The serious consequence of osteoporosis is fracture, of course, also includes various joint parts. To start eating a calcium-rich, low-salt and moderate protein diet, such as milk, from childhood, and focus on sun exposure and physical exercise.
3. Develop good habits. Pay attention to prevent the joints from getting wet and cold, especially in the season of climate change, and sweating, after drinking, sleep, wind, cold and humidity are most likely to attack the disease. When the knee joint is cold, the blood vessels contract and blood circulation becomes poor, which often makes the pain worse. Girls should not wear high heels for a long time. It is better to wear loose shoes with flexible soles, such as casual shoes with a sloping heel, which can reduce the impact of gravity on the joints and reduce the wear and tear on the joints. On the way to and from work or in the office when you feel tired feet can be replaced by a pair of flat shoes. The elderly should not lift heavy objects, should not climb high, carry heavy objects, so as not to cause joint damage.
4, pay attention to self-examination, early diagnosis and treatment. When there is repeated knee pain, soreness, leg pain downstairs, or uncomfortable joints when the weather changes and other symptoms, you should pay attention to, these are the initial signs of joint disease. When there are typical symptoms of joint disease joint pain, swelling and joint movement function is reduced should be promptly to the regular hospital examination, diagnosis.
5, reduce weight. Obesity often increases the burden on the joint surface, accelerating the wear and tear of the joint structure, aging, causing deformation arthritis. Obesity can also indirectly affect the joints through other metabolic complications, such as abnormal glucose tolerance, lipid abnormalities, etc.
6, pay attention to walking and labor posture, do not twist the body to walk and work. Avoid squatting for long periods of time, when engaged in long-term squatting work, such as auto mechanics, sand turners, it is best to sit on a small bench to a low sitting position, sitting and standing for long periods of time, but also to frequently change positions to prevent the knee joint fixed a posture and excessive force.
What is the treatment for osteoarthritis of the knee joint?
There is no specific treatment for degenerative arthritis, but pain can be reduced with proper treatment. In the case of an acute attack, rest for a short time. When an acute attack occurs, rest for a short time and braking. After an acute attack, appropriate activities and planned functional exercises can be performed. Appropriate exercise in the elderly can strengthen the stability of the joint and slow down the onset of degenerative changes. However, care should be taken to avoid over-activity and chronic injury. Various kinds of heat therapy and massage can promote local blood circulation and relieve pain.
(a) Take anti-inflammatory and analgesic drugs such as Fotarine, Mupiroc, Cilpro, etc., which can relieve the pain.
(2) Intra-articular injection of sodium hyaluronate can be used to lubricate the joints to protect them and reduce pain.
(3) Minimally invasive arthroscopic surgery: less invasive, faster recovery, and patients can walk on the ground the day after surgery.
(d) If the above treatments are not effective, joint deformity and joint dysfunction can be considered for artificial knee replacement surgery.
