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.

Introduction: Heterotopic ossification (HO) occurs in almost ⅓ of total hip arthroplasties (THAs). A direct anterior approach (DAA) with an orthopaedic table is less likely to cause HO than a posterior approach. Without an orthopaedic table, the exposure of the femur requires additional soft tissue release. Soft tissue trauma leads to the production of HO inductors. Our study evaluated the incidence of HO 6 months after THA and compared the results between DAAs without an orthopaedic table and posterior approaches. Methods: Retrospectively, 164 consecutive, primary THAs were included: 76 through a posterior approach and 88 through a DAA. The main objective was to measure the presence of HO on pelvis radiography 6 months after surgery. Results: The incidence of HO was significantly higher in the DAA group than in the posterior approach group (47.7% vs. 27.6%, respectively; p  < 0.01). The overall incidence of HO was 38.4%. No significant difference was found between the 2 approaches regarding the severity of HO. No significant risk factor for HO was identified other than the surgical approach. Discussion: In our study, the incidence of HO after THA in patients undergoing DAA without an orthopaedic table was higher than in patients undergoing a posterior approach after 6 months of follow-up. This result is closely related to the surgical trauma. It suggests that the minimally invasive feature of a surgical approach cannot be dissociated from the overall conditions in which it is performed.

Introduction The purpose of this study was to compare acetabular cup position for 2 cohorts of total hip arthroplasty (THA) patients who had a direct anterior approach. Methods 100 THA cases were performed with an anterior approach using intraoperative fluoroscopy (IF) to aid in cup positioning. Another group of 100 cases underwent THA with an anterior approach without the use of any fluoroscopy. Postoperative abduction and anteversion angles were measured using Martell's hip analysis software. Results Mean abduction angle was 43.2° (standard deviation (SD) = 4.5°) for the IF group versus 37.5°(SD = 7.4°) for cases without IF (p<0.001). 18% more cases with IF fell within the Lewinnek safe zone (p<0.001); however, a similar number of cases had over 50° of abduction. The mean anteversion angles of the two groups were also significantly different (IF 21.8° vs. 24.9°) (p<0.01). Conclusions There was significantly less variation in cup position among the cases using IF with regards to abduction.

Introduction: The direct anterior approach (DAA) has gained popularity in recent years for total hip arthroplasty (THA). Several authors reported significantly better early outcomes when compared to the posterior approach (PA). Nevertheless, controversy exists regarding longer-term benefits of the DAA. Methods: Data was prospectively collected and retrospectively reviewed for primary THAs conducted between July 2008 and July 2016. Patients who underwent DAA and PA with minimum 2-year follow-up for Harris Hip Score (HHS), Forgotten Joint Score-12 (FJS-12), Veteran RAND 12 Mental (VR-12 Mental), Veteran RAND 12 Physical (VR-12 Physical), 12-Item Short Form Survey Mental (SF-12 Mental), 12-Item Short Form Survey Physical (SF-12 Physical), visual analogue scale, and patient satisfaction were included. Propensity score matching was performed on the DAA and PA cohorts (1:1) based on the following variables: age, sex, body mass index, and laterality. Results: 205 DAA hips were satisfactorily matched to 205 PA hips. The DAA group had higher scores at final follow-up for VR-12 Mental ( p = 0.0145), VR-12 Physical ( p = 0.0236), SF-12 Mental ( p = 0.0393), and SF-12 Physical ( p = 0.0391). The DAA and PA groups had comparable HHS ( p = 0.0737) and FJS-12 ( p = 0.2900). Conclusions: Although the DAA and PA groups had different follow-up periods, both the DAA and PA groups reported favourable outcomes at minimum 2-year follow-up. While both groups achieved comparable scores for the majority of PROs including VAS and patient satisfaction, the DAA group achieved superior quality of life outcomes when compared with a propensity score matched group of PA surgeries.
