人体膝关节这个重要的“零件”就像一个机器的零件,用久了就会出现老化和磨损。作为一个负重关节,膝关节在不同的姿势下的负重也不尽相同。躺下来时,膝盖的负重几乎是0,站立和行走时,膝盖的负重是正常体重的1~2倍,而上下楼梯时,膝盖的负重是体重的3~4倍。下蹲时,膝盖的负重则可达到体重的8倍。负重越大,对于膝关节的磨损也就越严重,到了老年时膝关节的问题就会更明显。大于50岁膝盖疼别随便捶揉50岁之后,随着膝关节内的软骨、半月板出现老化,关节周围的肌肉、韧带也因为萎缩使得对膝关节的保护能力减弱,长期的负重也使得关节面软骨产生磨损 The important “part” of the human knee is like a part of a machine that ages and wears out after a long time. As a weight-bearing joint, the knee joint weight in different positions are not the same. When lying down, the knee’s weight is almost 0, standing and walking, the knee load is 1 to 2 times the normal weight, and up and down the stairs, the knee weight is 3 to 4 times the weight. When squatting, the weight of the knee can reach 8 times the weight. The greater the load, the more serious the knee wear, knee problems in old age will be more obvious. More than 50-year-old knees do not easily beat the knees 50 years old, with the knee cartilage, meniscus aging, the joints around the muscles, ligaments also because of shrinking so that the protection of the knee weaken the long-term load also makes the joints Facial cartilage wear
