Abstract: Articular cartilage is a thin layer of low-friction, wear-resistant, load-bearing, soft hydrated tissue covering articulating bony ends in diarthrodial joints. 摘 要 ：关节软骨是覆盖于骨关节面的一薄层低摩擦、耐磨损、负重的水化组织。
The most common type of joint in the human body is the diarthrodial joint -- knuckles and shoulders are examples -- in which two bones come together in a capsule. 人体中最常见的关节是运动关节，如指关节和肩关节等，关节处的一个囊状物把两根骨头结合在一起。
