Abstract
There are few studies evaluating total knee arthroplasty (TKA) in patients with dementia.
The purpose of this study was to evaluate the rate of revision, complication, emergency
department (ED) visitation, and discharge disposition in patients with dementia undergoing
primary TKA. In this retrospective study, we evaluated patients from 2007 to 2017
using a national database. Ninety-day complications in patients with dementia undergoing
TKA were increased risk of ED visitation and skilled nursing facility (SNF) disposition
(p ≤ 0.05). Two-year complications in patients with dementia undergoing TKA were increased
risk of ED visitation and SNF disposition (p ≤ 0.05). Patients with dementia undergoing TKA are at an increased risk of resource
utilization.
