Because of that, an orthopedic surgeon at Rush University Medical Center in Chicago has helped design a new replacement knee that better suits the build of a woman’s leg.
"There's a dramatic upswing in the amount of knee replacements that are being done and a dramatic upswing in the amount of knee replacements in women," said orthopedic surgeon Aaron Rosenberg. "In general, about 80 percent of women will have a shape that's distinctly different," he said.
Rosenberg notes that the knee implant designed for women is angled differently, thinner, and not as wide.
"When the component sits out in the soft tissues for a certain percentage of patients, the knees feel overstuffed and tight," Rosenberg says of the tradition unisex implants. He hopes that these will cause women to feel more comfortable with their new knee.
Only a few women have received the new implant thus far so little is known as to the long-time comfort of this new design. Time will determine the comfort and fit of the knee.
The knee implant for women is already FDA approved and Rosenberg hopes that, by the fall of this year, it will extend beyond the walls of Rush Medical Center and be offered to women around the country.
