New knee implant developed
When it comes to men and women, one size does not usually fit all. That’s why orthopedic surgeons at Rush University Medical Center in Chicago, Aaron Rosenberg, MD; Richard Berger, MD; and Wayne Paprosky, MD, collaborated with other surgeons to create the first FDA-approved knee replacement implant specifically designed to fit a woman’s anatomy.
“Abundant research indicates that a woman’s knee is not simply a smaller version of a man’s knee. The differences involve the shape of the bones and the position of the ligaments and tendons in the joints,” Rosenberg says.
Nearly two-thirds of the more than 400,000 annual knee replacement patients are women, according to the National Center for Health Statistics, and the numbers continue to increase each year. However, research shows that women with arthritis are three times less likely than men with arthritis to under-go the procedure, although they have more knee pain and resulting disability.
The new implant designed for women could change that.
“The implant is the best of both worlds,” Rosenberg says. “It’s based on the current implant we use, a highly successful implant with great mechanics and 14 years of clinical success. Only the shape and contour of this new implant are different, to make it feel more natural for women.”
