Is primary total hip arthroplasty in patients with Down's syndrome associated with increased complications at 2 years follow-up?

Journal Article (Journal Article)

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.
