Abstract

Introduction

Previous reports on primary total hip arthroplasty (THA) in patients with Down’s syndrome (DS) are often small and/or lack a comparison cohort, and thus it is challenging to draw meaningful conclusions about this group. The purpose of this study was to report on the post-operative complications in patients with DS undergoing primary THA, compared to a non-DS cohort.

Methods

In this retrospective study, we evaluated patients from 2010 to 2018 using a national database. We assessed surgical complications: closed reduction for dislocation, revision, resection, periprosthetic fracture, and infection in patients with a diagnosis of DS undergoing primary THA and compared them to a THA group of patients without DS. Patients undergoing THA for hip fractures were excluded. Complications were evaluated at 90 days and 2 years. Multivariable logistic regression analysis was used to adjust for age, sex, body mass index, and Charlson comorbidity index.

Results

At 90 days patients with DS had an increased risk of revision (OR 3.1, CI 1.14–8.41), but no significant risk of resection (OR 5.24, CI 0.73–37.8), closed reduction (OR 2.03, CI 0.28–14.59), infection (OR 1.48, CI 0.6–3.62), or periprosthetic fracture (OR 1.97, CI 0.27–14.14). At 2 years patients with DS had an increased risk of periprosthetic fracture (OR 5.88, CI 1.84–18.78), but no significant increased risk of revision (OR 1.82, CI 0.66–5.01), resection (OR 2.37, CI 0.33–17.17), or infection (OR 0.65, CI 0.2–2.07).

Conclusions

Primary THA in patients with DS is associated with increased 90-day revision, and periprosthetic fracture at 2 years.
