半月板损伤是引起膝关节疼痛的常见原因。当进行膝关节剧烈扭转、急停、变向等动作时，半月板容易发生撕裂。老年人因半月板退行性改变，强度下降，也容易发生半月板损伤。半月板外缘较小的损伤会自行愈合。但较大的损伤或内缘的损伤，往往需要手术治疗。 警告：请在有WIFI的场所观看视频，土豪请随意。 A Patient's Guide To Meniscus Tear 半月板撕裂病人指南 The menisci are two 'C' shape cartilage discs, locate between the thign bone (the femur)and the leg bone(the tibia). The menisci support your body weight act as shock-absorber, and allow the bones of your knee to glide easily during motion. 半月板是位于大腿骨（股骨）和小腿骨（胫骨）之间的两个“C”形的软骨盘。半月板支撑我们的体重，起着吸收震荡的作用，并允许膝关节的骨头在运动时可以自由地滑动。 The menisci can tear during strong twisting or pivoting motion and while slowing down or changing direction quickly. Meniscus injuries are common during sports or can occur among older adults because of meniscus's degeneration. 在做强烈的扭转或绕轴旋转动作或快速停下或改变方向等动作时，半月板可能发生撕裂。半月板撕裂在体育运动时很常见，老年人因为半月板退变，也容易发生半月板撕裂。 You may hear a popping sound when the menisci tears. You will develop swelling, tightness and pain that increases over several days. You may not able to straighten your knee, your knee may buckle, catch or lock in a position, making it difficult to stand or walk. 当半月板发生撕裂时，您可能会听到“啪”的一声响。还会逐渐出现肿胀、紧张和疼痛，在几天后逐渐加重。您可能不能伸直膝关节，膝关节可能会交锁固定在某个位置，造成走路或站立困难。 Minor tears on the outside of the menisci may heal on their own if there is a good blood supply. Surgery may be recommende for large tears on the outer section or for tears in the inner meniscus where there is a poor blood supply. 半月板外缘小的撕裂会自行愈合，因为局部血供良好。如果外缘巨大的撕裂，以及血液供应较差的中央部位的撕裂，建议进行手术治疗。 Arthroscopic knee surgery is commonly used to treat meniscus tears. Arthroscopic knee surgery uses an arthroscope, a thin instrument to visualize the joint and make surgical repairs without other having to open the joint. Because it's less invasive, arthroscopy could be have a decreased risk of infection, less pain, less bleeding and less swelling, and a shorter recovery period than traditional open surgical methods. 关节镜下膝关节手术常常用于治疗半月板撕裂。关节镜下膝关节手术使用关节镜，它是一种细长的设备，用于观察关节内部并进行手术修补，而不用打开关节。因为关节镜手术是微创的，因此降低了感染的风险，与传统开放手术相比，疼痛更轻，出血更少，肿胀更轻，恢复时间更短。 Let's take a look at arthroscopic knee meniscectomy. 让我们来看看关节镜下膝关节半月板切除术。 To begin, small incisions are made in the knee. The joint space is filled with sterile saline solution to expand the joint and provide a better view. The arthroscope is positioned to view the joint from different angles. Then surgical instruments are inserted through the small incisions. Torn meniscus pieces are trimed. A surgical shaver is used to smooth the remaining meniscus. The incisions are sutured and bandaged. 首先，在膝关节作几个小切口。关节间隙灌入无菌生理盐水，使关节间隙扩张，并提供更好的视觉效应。将关节镜通过小切口插入，从不同的角度对关节进行观察。然后从小切口插入手术器械，将撕裂的半月板的碎片剪除，用手术刨削器将残余的半月板边缘磨平。然后缝合切口并包扎。 Physical therapy will help you gain knee strength, flexibility and coordination. You may need to use a cane or crutches at first. Your surgeon will sometimes restrict the amount of weight that you can put on your foot but will gradually increase it as you heal. 物理治疗有助于您恢复膝关节力量、灵活性及协调性。起先，您可能需要使用手杖或拐杖。您的外科医生有时会限制您加在脚上的重量，但随着愈合会逐渐增加。 recovery time is different for everyone. It usually takes several weeks or months depending on the extent of your condition and the surgery procedure. Your surgeon will let you know what to expect. 恢复的时间因人而异。通常需要数周或数月的时间，取决于病情的程度及手术操作。医生会告诉您预期疗效。 （胡佰文 听译） 精彩视频魅力无限，收藏转发一起分享 您的每一次打开，都会有精彩的内容 您的每一次留言，都会有满意的答复 您的每一次点赞，都是对我们的肯定 您的每一次分享，都是对我们的鼓励 世界多姿多彩 感谢有您相伴 本公众号今后推送的文章关闭赞赏功能 如果觉得文章不错，您可以选择： 1.为作者点个赞 2.点击下方的广告 |
