No short-term benefit with gender-specific knees?

This article was originally published in The Gray Sheet

Executive Summary

Study of 85 women receiving a standard Zimmer NexGen LPS-Flex prosthesis in one knee and a Zimmer Gender Solutions gender-specific prosthesis in the other knee found that 84% of the patients felt there was no difference in either implant, according to an article published Aug. 18 in Journal of Bone and Joint Surgery. The mean postoperative Knee Society Score after two years was 95.5 points in the standard group and 96.5 point in the gender-specific group. Range of motion in the groups while lying down also was similar (125 degrees for the standard knee and 126 degrees in the gender-specific implant). However, the authors, led by Young-Hoo Kim, The Joint Replacement Center of Korea, note that "longer follow-up is needed." Zimmer, Smith & Nephew and Wright Medical are among firms offering gender-specific knees
