Experts have designed a knee implant specifically keeping women in mind. Surgeons consider this new knee replacement to reduce the pain suffered by some women after the operation, and improve mobility as previous ones would cause pain due to their ill fit. The traditional knee replacements were not very comfortable for the women as they are of narrower femurs, or thigh bones, than men. The new knee cap, called Gender Solutions, replaces the thighbone portion of the knee, and is designed specifically to match the shape of women's femurs. During knee replacement operations, the femur must be coated by a metal plate, and typically surgeons choose the best-fitting implant from a range of designs and sizes.

The surgeons believed the new knee implants would make a significant difference to the success of the implants in women, it would be some years before these effects would be confirmed by studies.
