A Prospective, Longitudinal Study of Outcomes Following Total Knee Arthroplasty Stratified by Gender

Abstract This study aimed to compare temporal trends in outcomes between men and women following TKA. A database of 272 TKAs at 7 years follow-up were evaluated for survivorship, functional, activity, and quality of life outcomes. Evaluation of implant survivorship, KSS scores, and ROM showed no significance differences between men and women, but both functional KSS scores and LEAS showed that men had significantly higher functional scores. The SF-36 physical component was found to be significantly better in men at multiple time points, whereas, the mental component was significantly better in men at pre-operative and 2 years. Both men and women benefit from TKA, however, men have higher levels of function and activity both prior to and after TKA than women.
