Abstract
Knee osteoarthritis is a common form of arthritis, often treated by total knee arthroplasty
(TKA). Complications can arise after TKAs, which may necessitate revision TKAs and
further treatments. However, there remains a paucity of literature regarding influence
of gender on postoperative complication rates after revision TKA. 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. This study included 9,914 patients who underwent revision TKA (females = 5,728
[57.8%]; males = 4 186 [42.2%]). Male patients were shown to be at greater risk for
developing 7 of 17 complications compared with female patients, and female patients
were shown to be at greater risk for urinary tract infection (UTI) development. Multivariate
analysis showed males as an independent risk factor for four complications and females
as an independent risk factor for UTI development. Male patients were more likely
to develop more complications postoperatively than female patients. Although the possibility
of developing complications is relatively low, orthopaedic surgeons should be aware
of increased postoperative complication rates when counseling patients who undergo
revision TKA.
