Total hip arthroplasty (THA) is performed more frequently in patients with systemic lupus erythematosus (SLE) than in the general population. However, whether patients with SLE have higher complication rates than patients with osteoarthritis (OA) is unknown. This study compares adverse events (AE) in SLE with OA controls.Methods. Patients in our institution’s registry were eligible. SLE was identified by the International Classification of Diseases, 9th ed code. AE were identified by chart review and questionnaire. Patients with SLE were matched with OA controls. Multivariate regression was performed to identify independent predictors of AE.Results. Fifty-eight patients with SLE THA were matched with 116 OA controls. Of the patients with SLE, 47.4% had Charlson-Deyo comorbidity scores (excluding SLE) > 1 versus 13.1% of OA (p < 0.0001). Length of stay was longer for SLE (6.0 days vs 4.7 days, p = 0.0008). Patients with SLE had more falls (10.3% vs 1.7%, p = 0.017), deep vein thrombosis (5.2% vs 0%, p = 0.036), acute renal disease (8.6% vs 0%, p = 0.004), wound infections (6.9% vs 0.9%, p = 0.043), and revision surgeries (5.2% vs 0%, p = 0.036). In a logistic regression controlling for comorbidities, SLE had an increased risk of AE (OR 3.77, 95% CI 1.74–8.16). Comorbidity scores were not significantly associated with AE. Among those with SLE, there were no significant differences in AE in those taking corticosteroids.Conclusion. SLE is an independent risk factor for AE after THA. Patients with SLE had higher rates of falls, acute renal disease, infections, and revision surgeries than matched OA controls. Further research is needed to understand the causes of increased AE in patients with SLE.
