Abstract

Background: Knee osteoarthritis is a common form of arthritis often treated by total knee arthroplasty (TKA). Complications often arise after TKAs, which may necessitate revision TKAs and further treatments. However, there remains a paucity in the literature regarding influence of gender on post-operative complications rates of those undergoing revision TKA.

Methods: A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program database. Patients who received revision TKAs between 2007 and 2014 were identified and recorded as male or female. Univariate and multivariate analysis was used to evaluate the incidence of multiple adverse events within 30 days of revision TKA.

Results: This study included 9,914 patients who underwent revision TKA (females= 5728 [57.8%]); (males= 4186 [42.2%]). Male patients were shown to be at greater risk for developing seven of 17 complications compared to female patients, and female patients were shown to be at greater risk for UTI development. Multivariate analysis showed males as an independent risk factor for 4 complications, and females as an independent risk factor for UTI development.

Conclusion: Male patients were more likely to develop more complications post-operatively than female patients. Although the possibility of developing complications is relatively low, orthopedic surgeons should be aware of increased post-operative complication rates when counseling patients who undergo revision TKA.
