汉英对照/膝盖是骨关节炎最脆弱的关节之一
< 汉英对照
膝盖是骨关节炎最脆弱的关节之一。 持续施加压力后，膝盖的软骨可能开始分解，导致膝盖的骨骼相互摩擦，从而导致骨关节炎。 到70岁时，将近三分之一的美国公民患有膝盖骨关节炎。
The knee is one of the most vulnerable joints for osteoarthritis. After continuous pressure is applied, the cartilage of the knee may begin to decompose, causing the bones of the knee to rub against each other, leading to osteoarthritis. By the age of 70, nearly one-third of American citizens have knee osteoarthritis.
