膝关节是人体最大、最复杂的关节,它仅仅靠一个狭小的接触面支撑整个身体的重量。平躺时膝盖的负重几乎是零,站起来和平地走路时负重是体重的1~2倍,上下坡或上下楼梯时是3~4倍,跑步时是4倍,蹲和跪时是8倍。因此,我们的膝关节常常不堪重负,出现各种毛病或疼痛。数据显示,我国约有1.2亿人患有骨关节炎,几乎每10人中就有1个。目前我国50岁以上的人群中,一半人有此困扰,60岁后患病率达60%,到了70岁,几乎每个老年人都会患上此病。
The knee joint is the largest and most complex joint in the body, supporting the weight of the entire body with only a narrow contact surface. When lying down knee load is almost zero, stand up and walk peacefully when the weight is 1 to 2 times the weight, on the downhill or up and down the stairs is 3 to 4 times, 4 times when running, when squatting and kneeling is 8 times . As a result, our knees are often overwhelmed with various problems or pains. Data show that about 120 million people in our country suffer from osteoarthritis, almost one in 10 people. At present, half of our population over the age of 50 has this problem. The prevalence rate is 60% after 60 years of age. By the age of 70, almost every elderly person will suffer from this disease.
