Impact of Dementia on Perioperative Complications in Elderly Patients Undergoing Total Knee Arthroplasty: A Retrospective National Inpatient Sample Database Study.

ABSTRACT:

Background

Dementia is widely recognized as a factor that influences the outcomes of total knee arthroplasty (TKA). However, recent studies have not fully elucidated the effects of dementia on perioperative medical and surgical complications, as well as in-hospital resource utilization. The objective of this study is to evaluate the specific impact of dementia on perioperative outcomes in elderly patients undergoing TKA.

Methods

Data on elderly patients undergoing TKA were extracted from the National Inpatient Sample database (2010-2019). Patients were categorized into a dementia group and a non-dementia group. Propensity score matching (PSM) was employed to control for differences in demographics, hospital characteristics, and comorbidities. Multivariate logistic regression
