Researchers Offer Alternative to Knee Replacement

研究人员提供了替代膝关节置换术的方法

Chuck Stenger, a retired firefighter had bad knees for decades. Every time I would kneel down or go to climb a ladder on the fire department and doing squats, when I was working out, I could feel it but I worked with it. He was diagnosed with osteoarthritis, a condition that wears away the cartilage between the bones of the knee. It's progressive and at some point the knee many need to be replaced but researchers at Ohio State University's Wexner MEdical Center fitted him with this new device instead.

查克·斯坦格,一个退休的消防队员,几十年来膝盖都不好。每次我跪下来或爬上消防队的梯子蹲下时,在我锻炼的时候,我都能感觉到,但我一直在努力。他被诊断出患有骨关节炎,这是一种磨损膝盖骨间软骨的疾病。这病会逐步发展的,在某种程度上,膝盖需要更换,但俄亥俄州立大学韦克斯纳医学中心的研究人员为他安装了这种新装置。

A shock absorber, it really looks like his car shock absorber is gonna be placed right on the inside part of the knee to take some of the load off that inner portion and shift it towards the outside part of the knee. This animation shows how it works.

一个减震器,看起来他的汽车减震器会放在膝盖内侧,把里面的部分卸下来,然后把它移到膝盖外侧。这个动画演示了它的工作原理。

It takes pressure off the joint reducing pain, slowing the advance of the osteoarthritis that generally leads to most knee replacements. I think if we're successful, that decrease the number of total joints that are required in the United States year by year, there are only increasing. And what we're trying to do is to limit it as much as possible. For Chuck the Calypso knee system as it is called could delay knee replacement surgery by decades while easing his pain and letting him get on with his life.

它能减轻关节的压力,减轻疼痛,减缓骨关节炎的发展,而骨关节炎通常会导致大部分的膝关节置换。我认为,如果我们成功了,那么每年减少美国所需的关节总数,这数字只增不减,我们要做的就是尽可能地限制它。对查克来说,卡利普索膝关节系统可以推迟数十年的膝关节置换手术,同时减轻他的疼痛,让他继续他的生活。

I want to be able to start doing some of the things I used to do. There are about 600, 000 knee replacement surgeries done in the U. S. every year and according to the World Health Organization, osteoarthritis afflicts between 10 to 15% of the world population. If this surgery goes well the procedure should become widely available in the US sometime in the next five to ten years.

我想开始做一些我以前做的事情。美国每年约有60万次膝关节置换手术,根据世界卫生组织的数据,骨关节炎的患病率在世界人口的10%到15%之间。如果这项手术进展顺利,在未来五到十年的某个时候,这项手术将在美国广泛应用。
