- Abstract
<bold>Purpose: </bold>The main purpose of this study was to compare the outcome of total hip arthroplasty (THA) via the direct anterior approach (DAA) using a dual-mobility cup (DMC) in patients with femoral neck fracture to those in patients undergoing elective THA for osteoarthritis.<bold>Patients and Methods: </bold>We retrospectively investigated 40 hips with femoral neck fracture (group A), and 81 hips with osteoarthritis (group B). THA via the DAA using the DMC was performed in both groups. A primary/secondary outcome variable were the presence of dislocation/operative time, intra- and/or peri-operative complication, and mortality.<bold>Results: </bold>Dislocation did not occur in either group. The complication rate was slightly higher in group A than in group B, but not statistically significant.<bold>Conclusion: </bold>THA with the DMC using the DAA was as effective for femoral neck facture as it was for elective THA in patients with osteoarthritis.
