Manufacturers of everything from running shoes to deodorants, a substance to remove unpleasant odors, design products specifically for women. One of the latest entries: the first artificial joint created for—and heavily advertised to—females. Doctors say it’s too soon to tell whether the Gender Knee represents a giant leap for womankind or if it gives its maker, Zimmer Holdings Inc., a leg up in the market.
In the case of the knees, according to Zimmer, here’s how men and women are different: First, the kneecap, is thinner in women. Also, women’s wider hips create a different angle between the knee and pelvis—the wide, curved group of bones at the level of hips, which can mean the kneecap gets pulled to the side when the muscles contract. And the end of the thighbone is typically narrower in men. Most artificial knees were modeled on the male anatomy—which may explain why knee replacements in women aren’t as successful when measured by reported pain and do-over rates.
But will the new (and more expensive) replacement actually serve women better? "In theory, yes, but the evidence isn’t there," says Kimberly Templeton, an associate professor of orthopedic surgery (prevention or correction of disorders of the bones and associated muscles and joints) at the University of Kansas Medical Center and a spokesperson for the American Academy of Orthopedic Surgeons. Sheryl Conley, Zimmer’s chief marketing officer, says seven studies now underway will look at patient satisfaction and range of motion. Preliminary data will be available in a year or so. Anatomical differences aside, Templeton says, replacement knees may not perform well in women in part because females tend to delay surgery—sometimes until they’re bound to the house by disability.
In addition, it’s not clear that the manufacturer’s specialized design will translate to less pain, says Steven Haas, an orthopedic surgeon and chief of the knee service at the Hospital for Special Surgery in New York. For example, making the front of the replacement knee thinner by one twenty-fifth of an inch won’t necessarily make a noticeable difference to recipients. Having a correctly fitted device is clearly important, says Haas, who notes that other companies have modified their smaller knees to account for gender differences in anatomy. (Haas has consulted with Smith & Nephew, a rival to Zimmer.)
More important, says Haas, is to find a skillful surgeon. Differences between implants, he argues, are relatively minor compared to the technique of the surgeon putting them in.
According to Paragraph 2, knee replacements in women haven’t achieved great success in that _____.
选项
A、women have thinner kneecap or patella than that of men
B、women’s wider hips make the artificial knee pulled to the side
C、artificial knees are designed based on the features of men’s body
D、women have wider end of the thighbone than that of men
答案
C
解析
事实细节题。题目问原因,寻找答案时要特别留意why或because等字眼。第二段第四句why表明原因:女性膝关节置换手术的成功率比男性低是因为大部分的人造膝盖都是依照男性的骨骼构造制作 的,故C项正确。
