Background: The aim of this study was to investigate whether the direct anterior approach (DAA) to total hip arthroplasty (THA) resulted in a shorter length of stay (LOS) in surgeons new to the approach when compared to their previously used approach. Perioperative complications were also assessed.
Methods: We examined 93 DAA THA performed by 3 hip arthroplasty surgeons at a single institution comparing these to their previous 166 operations performed using the lateral or posterior approach.
Results: Fixed-effects generalized linear modeling demonstrated that patients who underwent THA by the DAA had 26% shorter LOS than those who were operated on using lateral or posterior approaches (adjusted risk ratio = 0.74; 95% confidence interval = 0.65-0.84; P < .001). A greater proportion of DAA patients were discharged directly home (98% vs 87%, F (1,233) = 8.12, P = .005) and complication rates were comparable between groups.
Conclusion: The DAA can reduce patient LOS and may be a valuable addition to enhanced recovery pathways. Our findings also suggest that surgeons transitioning to the DAA do not have an increased complication rate when compared to their previous approach.

Introduction: In 2020, 368 million people globally were affected by knee osteoarthritis, and prevalence is projected to increase with 74% by 2050. Relatively high rates of dissatisfactory results after total knee arthroplasty (TKA), as reported by approximately 20% of patients, may be caused by sub-optimal knee alignment and balancing. While mechanical alignment has traditionally been the goal, patient-specific alignment strategies are gaining interest.

Introduction: Patients who have poorly controlled diabetes mellitus are at increased risk of periprosthetic joint infection (PJI). Nevertheless, an optimal preoperative hemoglobin A1c (HbA1c) threshold has not been established. This study sought to identify preoperative HbA1c thresholds that were predictive of adverse outcomes for total hip (THA) and total knee arthroplasty (TKA) patients.

Background: The gluteus medius and minimus muscles play a critical role in hip biomechanics, however there is a paucity of literature examining the impact of preoperative gluteal pathology on outcomes following total hip arthroplasty (THA). This study compared pain, satisfaction, and functional outcomes among patients who had and did not have preoperative gluteal pathology after direct anterior (DA) THA.
Methods: Using an institutional total joint registry, patients undergoing DA THA for osteoarthritis between 2010 and 2022 were retrospectively reviewed.

Introduction: The choice between cemented and cementless fixation in primary elective total hip arthroplasty (THA) remains a subject of ongoing debate. However, comparisons between the two are subject to limited adjustments for patient characteristics, diagnoses, and surgical factors, as well as by limited outcome time endpoints. Our study aimed to compare the effect of femoral fixation on safety and implant survival outcomes in matched patients.

Background: Ballistic fractures of the femoral neck, rare injuries that overwhelmingly affect younger adults, pose significant challenges to the treating surgeon. However, there is limited literature that the treating surgeon can leverage to guide their treatment decisions. The goal of this study is to describe the demographics, associated injuries, outcomes, and complications associated with ballistic femoral neck fractures.
