Abstract
BACKGROUND: Total hip arthroplasty (THA) performed using the direct anterior approach (DAA) has demonstrated favourable early-, mid-, and long-term outcomes. However, the traditional femoral release technique remains technically demanding and is associated with challenges and a heightened risk of complications. This study aimed to compare the clinical outcomes of patients who underwent THA with DAA performed using either the femoral-release-first (FRF) or the traditional approach (TA) strategy. METHODS: A retrospective analysis of demographics, clinical and radiological outcomes, and occurrence of complications was performed using data from 106 patients between 2018 and 2019. The patients were categorised into two groups: FRF (44 hips) and TA (69 hips). RESULTS: The FRF group showed a reduced operative time, haemoglobin (Hb) drop, postoperative hospital stay, and more optimal acetabular cup anteversion angles. Furthermore, during the first 2 months postoperatively, the FRF group demonstrated superior visual analogue scale, Harris Hip, and Oxford Hip scores. In the TA group, two hips experienced greater trochanter fractures, and one experienced delayed incision healing. CONCLUSIONS: Compared with the TA, employing the FRF strategy during THA with DAA resulted in improved outcomes within the first 2 months postoperatively and comparable functional recovery beyond this period. The FRF method exhibited advantages such as favourable acetabular exposure and alignment and a reduced risk of complications. Therefore, the FRF strategy may be a favourable option.
