Sickle cell disease (SCD) is associated with impaired vascular function and progressive vaso-occlusive injury to bones. We used the Nationwide Inpatient Sample to identify all THA and TKA admissions between 1998 and 2010. After controlling for patient age, gender, insurance, race, and comorbidities, the risk of complication among admissions with SCD was 152% higher (P<0.001) for THA and 137% higher (P=0.001) for TKA. Patients with SCD had a length of stay that was 42% longer (P<0.001) for THA and 20% longer for TKA (P<0.001), and hospital charges that were 19% higher (P<0.001) for THA and 16% higher (P=0.001) for TKA. Orthopedic surgeons should counsel potential THA and TKA candidates with SCD of these risks prior to admission.
