Objective: The aim of the study was to compare the dislocation rate between total hip arthroplasty (THA) via direct anterior approach (DAA) and via posterior approach (PA). Methods: We compared a consecutive series of 139 THAs via DAA with 177 THAs via PA. All study patients received ceramic-on-ceramic bearing surfaces and similar uncemented prostheses. Dislocation-free survival after THA was estimated using the Kaplan–Meier survival method and compared between groups using the log-rank test. Results: In the DAA group, none of 139 hips experienced dislocations in five-year-average follow-up. In the PA group, seven hips experienced dislocations among 177 hips (4 %). The dislocation was significantly less in the DAA group compared to the PA group (p = 0.033). Conclusion: The dislocation rate of THA via DAA was significantly less than that of THA via PA.

The aim of this study was to investigate the radiological and clinical outcome of the direct anterior approach (DAA) in total hip arthroplasty (THA) using a collared cementless femoral short-stem. This retrospective study included 124 patients with 135 THAs operated from 2014 to 2016 using a collared cementless triple tapered hydroxyapatite-coated femoral short-stem (AMIStem H Collared®, Medacta International, Castel San Pietro, Switzerland) implanted with a DAA. Follow-up was performed at three months, 12 months, and five years. Clinical outcome was assessed using the hip osteoarthritis outcome score (HOOS) and radiological analysis was done using conventional radiographs, which included evaluation of the femur morphology based on Dorr classification, of radiolucencies based on the Gruen zone classification and of stem subsidence. The mean age was 67.7 ± 11.3 years and the mean body mass index (BMI) was 27.4 ± 4.4 kg/m2. The stem survival rate at five years was 99.1% with one revision due to recurrent dislocations. Mean HOOS score improved from 40.9 ± 18.3 preoperatively to 81.5 ± 19.7 at three months, 89.3 ± 10.9 at 12 months, and 89.0 ± 14.0 at five years (all with p < 0.001). No significant correlations were found between age, femoral bone morphology, BMI and HOOS, and the appearance of relevant radiolucencies.
