The knee is the largest and most complex joint of the human body, and it is also one of the few joints in our body.

The knee is the body's largest load-bearing joints, normal knee joint average bearing the weight of a person, but bear the weight of more, the degeneration of articular cartilage, the greater the probability of wear, related tendon, meniscus injury prone, knee joint degeneration in early osteoarthritis rapidly.

Knee joint weight

1 flat when the load is almost 0.

2 stand and walk on the road, weight is about 1 ~ 2 times.

3 up or down the stairs, the load is about 3 ~ 4 times.

4 when running, the weight is about 4 times.

5 play, the weight is about 6 times.

6 squatting and kneeling, the knee joint weight is about 8 times.

For example, a person with a weight of 60kg, every step on the knee joint about 240kg weight. Overload operation, like a machine, reduces its use.

The knee is only 15 years old:

Before the age of 15:

The knee joint is in the development stage, and the growth pain of puberty is near the knee.

15 years old ~30 years old:

The knee is in perfect condition, which can be said to be tireless. As long as it does not destroy the knee joint organization, basically can not feel its existence.

30 years old ~40 years old:

Patella cartilage produced early mild wear, there will be a vulnerable period, short-term knee pain, continued for several weeks to several months, some people will not even be aware of. The patella cartilage is a white transparent cartilage with a thickness of 2~3 mm thick in the human knee joint, which can cause the impact of knee joint buffering.

But because of patellar cartilage no nerves, so in the whole layer before wear only in a "vulnerable period sounded a warning signal, in this period of time to avoid strenuous exercise. Also from this time, the use of the knee can no longer be arbitrary.

40 years old ~50 years old:

In the long walk, prone to the medial knee pain, relieved by rest. The body's 60% body weight is supported by the medial knee, so the medial meniscus degeneration occurs relatively early. Because of the nerve distribution on the meniscus, people can feel the pain in the process of degeneration. The arrival of this phenomenon reminds you: you should start to maintain the joint.

Above 50 years old:

The knee will feel a significant pain, because the patella cartilage "life" has been to the cartilage full-thickness wear, arthritis has been produced. At this point should be used to save joints, reduce strenuous exercise, especially up and down stairs, climbing and squatting, if necessary, you can use crutches to reduce the pressure on the knee joint.

Causes of knee pain in the elderly

People into middle age, knee tendon and ligament to degenerative changes in articular cavity secretion of synovial fluid decreased, bone joint surface friction wear long bone formation, joint surrounding tissue due to inflammation and other reasons to prevent the fiber adhesion, so the elderly often feel stiff knee joint.

Activities will be issued when the "click" play a sound or sound of friction, in cold or excessive activity will induce pain, swelling, joint effusion, serious will also cause the elderly joint deformity, the formation of disability. Specifically, the causes of knee pain in the elderly have the following reasons:

Chronic synovitis of knee joints: performance for chronic pain and swelling. Synovial fluid, synovial hypertrophy.

Offset: activities of knee joint after patellar achesweakness improved after the break, squat pain.

The free body of knee joint: Patients with leg or weak joint friction sound stuck, infrapatellar.

Prepatellar bursitis: had a history of trauma, caused by anterior knee pain, check local tenderness.

Osteoarthritis: sedentary or squat after standing up, up and down the stairs, the joint pain is obvious, rest after remission.

Pseudo gout: male patients, hair in the knee joint. At the onset of swelling and pain, high temperature, limited function. X-ray films showed calcification of meniscus and articular cartilage.

Avascular necrosis of the femoral head: knee pain.

Pain in different parts of the knee

Lateral pain of the knee joint.

The front knee pain, also called patellofemoral pain.

Above the knee joint pain, may be four head tendinitis.

The knee bone above and medial tibial pain may be bursitis.

Daily care of knee joint ache

Do not go too long, more than two bus stations, the best car or ride; when you feel uncomfortable when you should immediately rest.

Do not rely on advertising, prohibit the exercise of large amount of exercise, such as running, climbing.

Avoid squat, squatting or kneeling position. Such as the squat, Tai chi.

The proper control of diet, maintain the ideal weight to reduce the burden on the knee.

Keep warm, can wear pants, knee to knee joint protection.

The choice of shoes is very important. A pair of shoes, high quality, not only can let you walk comfortable, can also impact and pressure to reduce the movement of knee joint bearing.

In addition, the best choice at this time should be to see the joint surgeon.
