No clinical benefit in gender-specific knee prostheses in females after TKA .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2014;2(19):14 Acta Orthop. 2014 Aug;85(4):415-21Six randomized controlled trials were included in the meta-analysis, the purpose of which was to evaluate the clinical and radiographic outcomes of gender-specific prostheses to standard unisex prostheses in female patients undergoing total knee arthroplasty. Pooled data showed no significant benefit to using gender-specific components for total knee arthroplasty in females.

لماذا كانت هناك حاجة لهذه الدراسة الآن؟
Recent studies have identified gender differences in the anatomy of the distal femur, introducing the concept of gender-specific knee prostheses. As women account for a greater percentage of knee arthroplasties than men, the potential effect of gender on functional outcomes and implant survivorship has been identified. Current studies have failed to establish consensus; therefore this meta-analysis aims to compare the clinical and radiographic results of total knee arthroplasty in female patients receiving gender-specific prostheses to standard unisex prostheses.
ما هو سؤال البحث الرئيسي؟
Are gender-specific knee prostheses clinically favourable to unisex knee prostheses in female patients undergoing primary total knee arthroplasty?
- Data pooled from 5 studies suggested similar postoperative pain between gender specific knees (49/446 experienced pain) and unisex knees (48/446 experienced pain).
- 5 studies reported active range of motion of the knee in supine position and 3 studies in the weight bearing position; no statistically significant differences were observed between groups in terms of active range of motion in non-weight bearing (WMD: 0.57; 95% CI: -2.4 to 3.5; p=0.7) or weight-bearing conditions (WMD: 0.66; 95% CI: -2.0 to 3.4; p=0.6).
- KSS (reported in 4 studies), HSS (reported in 4 studies) and WOMAC (reported in 3 studies) scores were similar between treatment groups.
- From 3 studies, there was no statistically significant difference in preference of prosthesis (RR=1.1; 95% CI: 0.68 to 1.8; p=0.7). 3 studies reported the mean satisfaction score was similar in both groups (WMD: 0.04, CI: -0.52 to 0.60; p=0.9).
- 4 studies revealed that the gender-specific femoral component did not fit better than the standard femoral component (RR=0.45; 95% CI: 0.36 to 0.56; p<0.001).
- Postoperative complications were reported in 4 studies, all of which had low complication rates and were comparable between groups (RR=1.0; 95% CI: 0.42 to 2.3; p=1.0; I-squared: 0%).
- 5 studies mentioned radiographic results, but no statistically significant differences between the groups were found.
ما الذي يجب أن أتذكره أكثر؟
Gender-specific knee prostheses did not provide clinical advantages over unisex knee designs in female patients undergoing primary total knee arthroplasty with respect to pain, range of motion, functional scores, postoperative complications, patient satisfaction, femoral component fit, or radiographic results.
كيف سيؤثر ذلك على رعاية مرضاي؟
Despite theoretical benefits, there does not appear to be an advantage stemming from using gender specific knee prostheses in women undergoing total knee arthroplasty. However, the trials in this meta-analysis were limited by short follow-up periods. To better evaluate the comparative efficacy of both types of prostheses, longer studies are needed.
