In a study presented by Canadian surgeons at the knee society (American Academy of Orthopaedic Surgeons 75th annual meeting in San Francisco, California in March 2008), surgeons from London, Ontario presented a large study of 3,817 patients with 5,279 total knees, specifically assessing difference between males and females. It was found that women demonstrate statistically greater improvement in functional scores; women had a lower revision rate. They concluded that women do not have an inferior clinical outcome following total knee replacement using traditional implants. This data challenges the hypothesis by some implant manufacturers, that women require a specific prosthesis, as there is no objective data to substantiate that claim.
