Abstract
Background: Total hip arthroplasty (THA) is a successful treatment for hip osteoarthritis, but the optimal surgical approach for this procedure is a topic of debate. This review uses fragility analysis to determine the statistical fragility of randomized controlled trials (RCTs) comparing the 3 most common surgical approaches for THA: direct anterior, direct lateral, and posterior. Materials and Methods: A systematic review was conducted to identify RCTs comparing 2 of the 3 surgical approaches for THA. Dichotomous outcomes and study characteristics were extracted from each study that met the inclusion criteria. Fragility index (FI) and fragility quotient (FQ) were calculated for each significant outcome (P <=.05), and reverse fragility index and quotient (rFI and FQ) were calculated for each nonsignificant outcome (P>.05). Results: Our search yielded 20 studies in total, with 146 identified dichotomous outcomes. In total, the outcomes had a median FI of 5 and a median rFI of 5. Significant outcomes that favored the anterior approach had a median FI of 6, and significant outcomes that favored the posterior or lateral approach both had a median FI of 1. Conclusion: The RCTs comparing approaches to THA had a median FI of 5, signifying that the reversal of 5 events would be sufficient to change the significance of the entire outcome. This value is comparable to other FI values within the orthopedic literature, but subgroup analyses elucidated areas of greater statistical fragility, particularly in outcomes favoring either the lateral or posterior approach in THA.
