Background: Although it is normally perceived that knee morphometry contrasts exist amongst the female as well as male populations, the literature normally disproves the need for gender specific totalknee prosthesis clinically. It was noted that standard/unisex knee performs alike or better in female than male. As of late, high flex knees became accessible, that mechanically accommodate raised flexion but not many studies have contrasted these devices’ results in male and female to find out if there is any gender based contrast.
Methods and Results: We aimed to compare midterm functional outcomes as well as survivorship of large cohorts of male and female acquiring Cruciate Retaining (CR) high flex knee in 744 females (994 knees) and 469 males (641 knees). Kaplan Meier survival analysis was similar in genders, i.e., 97.5 % (95% CI: 96.7-98.9%) at 5.8 y for males and 97.5% (95% CI: 95.9-99.2%) at 5.9 y for females. Mean improvement in Knee Society score (KSS) Knee and KSS Function for male and female (51.2 vs. 45.3; 26.7 vs. 22.8) and Short Form Health Survey (SF12) Mental as well as Physical scores (0.3 vs. 2.3; 14.2 vs. 13.2) were identical with contrasts irrelevant clinically.
Conclusion: During stratification of motion results by preoperative values, we discovered nearly similar differences between preop and postop Range of Motion (ROM) as well as Peak Flexion (PF) values for both male and female. This demonstrates that a specific high flex knee configuration had similar clinical efficacy in both genders.Author(s): Hui Peng, Shenglin Lu, Yu Bai, Xu Fang, Hui Huang, Xiaoqiang Zhuang
