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.
