The “Bee’s Knees” for Women! – Gender-Specific Knee Replacement Implants

The lengthy list of differences between the sexes just had a new page added—gender-specific knee replacement implants. And for women anticipating knee replacement surgery, this is big news!
Sure, everyone knows men and women are put together differently, yet few know women have slight differences in the shape of their knees. That’s why gender-specific implants were exclusively designed for women in order to provide comfort and flexibility that may not be possible with a traditional joint implant.
Traditional knee implants for women are smaller than those for men, but don’t account for differences in the shape of the knee. “We’ve known that men and women’s femur and knee are different for many years, but it’s only been in the last three years that we have been utilizing different implants,” says Charles Toulson, MD, orthopedic surgeon at Medical Center of McKinney. “Now, we are able to customize knee replacements that feel better and accommodate the shape of women’s femur and knee.”
Exactly how do men and women’s knees differ? For starters, there are three key anatomical differences that make a woman’s knee joint unique: The end of a woman’s thighbone (femur) is smaller than a man’s. The shape of a woman’s knee is narrower. And the angle at which the knee joint comes together is different for men and women.
The angle at which the knee joint comes together is impacted by the natural difference in the shape and size of male and female hips. So, it stands to reason that the best knee replacement implant is the one that is best fitted to suit each individual.
“The implant should allow flexibility, free range-of motion, be comfortable and allow the patient to go about daily activities without pain or inconvenience,” Dr. Toulson says. “Since a gender-specific knee implant accounts for inherent differences in the joint anatomy of men and women, it is often the most appropriate option.”
Knee implants designed for women usually have thinner profiles than those for men. That is because the bone in front of a woman’s knee is less prominent than a man’s. A traditional implant may end up feeling “bulky” and cause pain, discomfort and limited range of motion.
“Regardless of height, the shape of a woman’s knee is narrower than that of a man’s,” Dr Toulson says. “A joint implant designed specifically for women has a contoured shape to allow for a more comfortable and snug fit. This unique design also prevents the implant from overhanging the bone and potentially damaging surrounding ligaments and tendons. In addition, this custom-made implant designed specifically for the female knee allows the leg to extend and flex in a natural, painless motion by accommodating this unique angle.”
