To evaluate whether proposed anatomical differences between male and female knees justify gender-specific implant designs and whether women experience inferior outcomes with conventional total knee arthroplasty.
Conducted a Level IV systematic review of peer-reviewed literature analyzing clinical outcomes in women compared to men following traditional total knee arthroplasty.
Evaluated published empirical evidence supporting three proposed gender-based anatomical distinctions: increased Q angle, reduced condylar prominence, and altered condylar aspect ratios.
Women demonstrated equal or better clinical outcomes compared to men following traditional total knee arthroplasty.
Evidence failed to support proposed gender differences in Q angles or anterior femoral condyle prominence, while differences in femoral condylar aspect ratios were too small to produce a clinical effect.

No takes yet. Share an insight, caveat, or question.

Implication

Systematic review finds equivalent outcomes and minimal anatomical differences for standard knee implants in women, indicating female-specific designs lack clinical necessity.
