“…[ 26 ] Both robot-assisted posterior approach, fluoroscopyguided anterior approach, and conventional posterior approach can obtain minimal LLD, indicating that they can achieve accuracy in LLD well. [ 27 ] Specialdesigned prostheses,[ 28 ] surgeon-controlled table, and advanced fluoroscopic imaging techniques[ 29 ] can improve the biomechanical and physiological hip reconstruction, which subsequently enhance the radiographic and clinical outcomes.…”

Objectives: This study aims to investigate the possible association and comparison between anterolateral approach (ALA) and posterolateral approach (PLA) and postoperative lower limb discrepancy (LLD) in selective total hip arthroplasty (THA). Patients and methods: April 2021 and July 2021, a total of 266 consecutive patients (126 males, 140 females; mean age: 46.7±13.6 years; range, 22 to 60 years) who underwent unilateral primary THA via the ALA or the PLA were retrospectively analyzed. The operations were performed by a single surgical team. All patients were divided into two groups according to the approach: ALA group (n=66) and PLA group (n=200). Relevant data were recorded. Diagnosis including hip osteoarthritis, developmental dysplasia of the hip (DDH), aseptic avascular necrosis (AVN), and inflammatory arthritis were noted. Perioperative follow-up radiographs were evaluated and measured to compare the postoperative LLD and offset. The association between two approaches and postoperative LLD and offset was analyzed using the univariate and multivariate linear regression analysis. Results: The mean follow-up was 20±3.7 (range, 16 to 25) months. Univariate analysis revealed that the postoperative LLD, the postoperative acetabular offset, and hospital costs were lower in the ALA group than the PLA group (p <0.01). However, the offset and length of stay were comparable between the two groups (p>0.05). Multivariate analysis revealed that the PLA (β=4.71; 95% confidence interval [CI]: 1.78 to 7.64), preoperative LLD (β=0.29; 95% CI: 0.21 to 0.37), DDH (β=5.01; 95% CI: 1.47 to 8.55), and AVN (β=3.81; 95% CI: 0.50 to 7.12) were the main contributors to the postoperative LLD. Conclusion: Our study results suggest that the ALA may be superior to the PLA in controlling the postoperative LLD among some of the selective unilateral primary THA patients. Both the ALA and the PLA were comparable in terms of the restoration of offset.

“…Intelligent HIP smart tool, a newly introduced smart tool providing an accurate and real-time intraoperative leg length measurements, is properly useful for an improved measurements [22]. Special-designed prostheses [23], surgeon-controlled table, and advanced uoroscopic imaging techniques [24]. would improve the biomechanical and physiological hip reconstruction and subsequently enhance the radiographic and clinical outcomes.…”

Objectives: Variable approaches for total hip arthroplasty (THA) are promoted but investigations of associations between the approaches and the postoperative lower limb discrepancy (LLD) are limited. We intended to compare the efficacy between the anterolateral approach (ALA) and posterolateral approach (PLA) in controlling of postoperative LLD. Methods: Two retrospective cohorts were established including patients undergone unilateral primary THA. Preoperative and latest follow-up radiographs were compared and evaluated. Two hundred and sixty patients (140 females and 126 males; aged 46.70 ± 13.62 years) were recruited with around 20 months follow-up postoperatively. Results: Univariate analysis identified lower postoperative LLD, lower postoperative acetabular offset and lower hospital costs in the ALA group than in the PLA group (p＜0.01), however, the femoral and global offset and length of stay (LOS) are comparable between (p > 0.05). Multivariable liner regression revealed that PLA, preoperative LLD, developmental dysplasia of the hip and aseptic avascular necrosis are major contributors to the postoperative LLD (p<0.05). Conclusions: This study illustrates that the ALA might be superior to the PLA in controlling the postoperative LLD among some of the THA patients. Both ALA and PLA are comparable in regard to femoral and offset and LOS.
