Does age increase perioperative complications for single-stage bilateral total hip arthroplasty?

The potential of post-operative complication may exclude elderly patients from undergoing single-staged bilateral total hip arthroplasty (SSBTHA). This study retrospective compared perioperative complications between SSBTHA patients <70 (N = 157) and ≥70 (N = 56) years of age. Patients ≥70 had significantly lower body mass index (p = 0.029) and had a higher ASA classification (p = 0.041) compared to patients <70. No differences in post-operative complications or transfusion rates were found between age groups. However, patients ≥70 were less likely to be discharged home. While SSBTHA can safely be performed in patients ≥70, the risk of transfusion may suggest pre-operative hemoglobin screenings, especially for patients ≥70.
