BILATERAL SIMULTANEOUS TOTAL HIP ARTHROPLASTY: A META-ANALYSIS OF 2063 CASES



Abstract

Comparison of the safety and efficacy of Bilateral Simultaneous Total Hip Arthroplasty (BSTHA) with that of staged (SgTHA) and unilateral (UTHA) was conducted using DerSimonian–Laird heterogeneity meta-analysis. Twenty three citations were eligible for inclusion. A total of 2063 BSTHA patients were identified. Meta-analysis of homogenous data revealed that there were no statistically significant differences between rates of thromboembolic events (p=0.268 and p=0.356) and dislocation (p=0.877) when comparing SgTHA or UTHA versus BSTHA procedures. Systematic analysis of heterogenous data demonstrated that mean length of stay was shorter in BSTHA as compared to SgTHA and UTHA procedure, blood loss was lower in BSTHA in all studies except one, whilst the surgical time was not different between groups. BSTHA was also found to be economically and functionally efficacious.
