Aim: To determine if there was a seasonal variation in adults undergoing total hip arthroplasty for end stage hip disease due to osteoarthritis (OA) or sequelae of developmental dysplasia of the hip (DDH).
Methods: The total hip registry from the author's institution for the years 1969 to 2013 was reviewed. The month of birth, age, gender, and ethnicity was recorded. Differences between number of births observed and expected in the winter months (October through February) and non-winter mo (March through September) were analyzed with the χ test. Detailed temporal variation was mathematically assessed using cosinor analysis.
Results: There were 7792 OA patients and 60 DDH patients who underwent total hip arthroplasty. There were more births than expected in the winter months for both the DDH ( < 0.0001) and OA ( = 0.0052) groups. Cosinor analyses demonstrated a peak date of birth on 1 October.
Conclusion: These data demonstrate an increased prevalence of DDH and OA in those patients born in winter.

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.

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.
