Abstract

BACKGROUND: Total hip arthroplasty (THA) after prior hip or acetabular fracture fixation is considered higher risk than primary THA, as studies have shown reduced implant survival and higher infection rates. The anterior-based muscle-sparing (ABMS) approach can potentially reduce some of these risks by utilizing a new surgical interval. The goal of this study is to analyze the efficacy of the ABMS approach for conversion to hip arthroplasty surgery after previous fracture fixation with comparison to posterior approach.

METHODS: This retrospective cohort study included patients with prior hip surgical intervention requiring hardware then converted to a THA using the ABMS or posterior approach at 1 institution between 2013 and 2020. Outcomes studied included postoperative complications, 30-day emergency department visits, 90-day readmission rates, any reoperation and patient-reported outcome measures.

RESULTS: A total of 85 patients (51 male and 34 female) in the ABMS group and 17 patients (9 male and 8 female) in the posterior group were included. Within the ABMS group, the mean age was 65.6 years (±16.2) with a mean body mass index of 27.5 kg/m

CONCLUSIONS: This study is the first to evaluate outcomes of conversion THA using the ABMS approach, when compared to the posterior approach. Our institution's experience demonstrates that the ABMS approach is safe and effective for conversion THA after prior fracture fixation.
