Racial, socioeconomic, and payer status disparities in utilization of unicompartmental knee arthroplasty in the USA.

Background: Unicompartmental knee arthroplasty (UKA) is a surgical treatment for knee osteoarthritis associated with lower morbidity compared with total knee arthroplasty (TKA) in patients with isolated unicompartmental knee arthritis. As disparities have been noted broadly in arthroplasty care, it follows that such disparities might be present in the utilization of UKA relative to TKA. This study therefore examined racial/ethnic, socioeconomic, and payer status differences in utilization of UKA.

Access to robot-assisted total knee arthroplasty varies significantly by race/ethnicity.

Background: Racial/ethnic disparities in access to total knee arthroplasty (TKA) have been extensively demonstrated. Over the past several years, there has been a rapid increase in the utilization of robot-assisted TKA (RA-TKA). Therefore, this study sought to determine whether previously established racial/ethnic disparities extend to access to RA-TKA relative to conventional TKA.

The Impact of Traveling Fellowships: Perspectives From Rothman-Ranawat Travel Fellows.

Background: Traveling fellowships, such as the Hip Society Rothman-Ranawat fellowship, offer orthopaedic surgeons the opportunity to enhance their skills, conduct research, and gain mentorship at top orthopaedic centers. This study aimed to assess the impact of the Hip Society Rothman-Ranawat traveling fellowship on an adult reconstruction surgeon's career.

Methods: A non-incentivized online survey was distributed to the 40 past recipients of the Hip Society Rothman-Ranawat traveling fellowship spanning from 2013 to 2023.

The Impact of the Dobbs v. Jackson Supreme Court Decision on Orthopaedic Residency Programs: A Collaborative Orthopaedic Education Research Group (COERG) Survey.

Recent changes in reproductive health care policy have now led to state-specific differences in abortion care access across the United States. Members of the medical community in particular have issued concerns regarding these new policies and their potential impact on graduate medical training.  Objectives: The purpose of this study was to sample orthopaedic surgery residency programs to gauge their perceptions of the Dobbs decision and its impact on residency training.

International medical graduates in orthopaedic surgery: An opportunity to improve diversity and inclusion?

Background/aims: Racial and ethnic minorities are under-represented in orthopaedic surgery despite efforts to promote diversity and inclusion in the specialty. The purpose of this study was to determine the proportion of international medical graduates (IMGs) in the surgical workforce and future residency pipeline. We further analyze IMG applicant qualifications relative to their US-based counterparts to assess the viability of recruiting IMG candidates as one strategy to advance diversity and inclusion in orthopaedic surgery.

Routine Prescription of Proton Pump Inhibitors in the Perioperative Period is Associated With Decreased Rates of 2-Year Revision Surgery After Total Hip and Knee Arthroplasty.

Background: Proton pump inhibitors (PPIs) are often prescribed in conjunction with nonsteroidal anti-inflammatory drugs after total hip arthroplasty (THA) and total knee arthroplasty (TKA) due to their gastroprotective effects. In animal studies, it has been suggested that PPIs have immunosuppressive effects and impair fracture healing; however, the association between PPI use and adverse events following THA and TKA has not been well-studied.

Methods: An administrative claims database was queried for patients who underwent elective THA from 2010 to 2019.

Who Bears the Burden? Understanding the Socioeconomic Patterns of Educational Debt in Orthopaedic Surgery Residency Candidates.

Background: Educational debt is commonly observed among applicants to orthopaedic surgery residency programs; however, an understanding of the debt burden among minority and nonminority applicants is not well established. Thus, this study aimed to fill these knowledge gaps by examining the extent of and factors shaping educational debt among orthopaedic surgery applicants.

Questions/purposes: (1) What is the educational debt burden among orthopaedic surgery residency applicants? (2) After controlling for relevant confounding variables, what factors are independently associated with increasing levels of educational debt? (3) After controlling for relevant confounding variables, are individuals classified as an underrepresented minority or those with educational debt and socioeconomic disadvantage less likely to match in orthopaedic surgery?

Methods: A retrospective evaluation of orthopaedic surgery residency application data from the American Association of Medical Colleges was analyzed from 2011 to 2021.

Decreased Risk of Readmission and Complications With Preoperative GLP-1 Analog Use in Patients Undergoing Primary Total Joint Arthroplasty.

Background: There has been considerable interest in the use of GLP-1 receptor analogs (GLP-1 RAs) for weight optimization in patients undergoing elective arthroplasty. As there is limited data regarding the implications of their use, our study aimed to evaluate the association between preoperative GLP-1 RA use and postoperative outcomes in patients undergoing primary total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Methods: The TrinetX research network was queried to identify all patients undergoing primary THA or TKA between May 2005 and December 2023 across 84 health care organizations.

Open Access Publication in Total Ankle Arthroplasty Literature Is Associated With Increased Social Media Attention, but Not Increased Citations.

Background: Open access (OA) publications are increasingly common in orthopaedic literature. However, whether OA publications are associated with increased readership or citations among total ankle arthroplasty (TAA) literature is unclear. We hypothesize that compared with non-OA status, OA status is associated with increased social media dissemination, and readership, but not with citation count.

Quercetin Exerts Anticonvulsant Effect through Mitigation of Neuroinflammatory Response in Pentylenetetrazole-induced Seizure in Mice.

Epilepsy is a chronic disease of the brain characterized by seizures. The currently available anticonvulsants only treat symptoms with serious adverse drug reactions. Therefore, there is need for new therapeutic intervention that will prevent epileptogenesis with greater therapeutic success.

Cementless Total Knee Arthroplasty: A Resurgence-Who, When, Where, and How?

Background: Total knee arthroplasty (TKA) is one of the most common procedures in orthopaedics, but there is still debate over the optimal fixation method for long-term durability: cement versus cementless bone ingrowth. Recent improvements in implant materials and technology have offered the possibility of cementless TKA to change clinical practice with durable, stable biological fixation of the implants, improved operative efficiency, and optimal long-term results, particularly in younger and more active patients.

Methods: This symposium evaluated the history of cementless TKA, the recent resurgence, and appropriate patient selection, as well as the historical and modern-generation outcomes of each implant (tibia, femur, and patella).

Prevalence and factors associated with contraceptive use among sexually active adolescent girls in 25 sub-Saharan African countries.

Introduction: Various countries in sub-Saharan Africa have taken divergent steps toward achieving the Sustainable Development Goal's target of universal access to sexual and reproductive health-care services by 2030, particularly among sexually active adolescent girls who are at risk of unplanned pregnancies and sexually transmitted infections. However, because contraceptive use among sexually active adolescents remains unexplored in sub-Saharan Africa, the researchers intended to examine the prevalence and factors associated with contraceptive use among adolescent girls who had been sexually active in the previous four weeks.

Materials And Methods: Cross-sectional data from the most recent demographic and health surveys of 25 sub-Saharan African countries on 16,442 sexually active adolescent girls were analyzed.

Towards Visualizing Early-stage Osteonecrosis using Intraoperative Imaging Modalities.

Osteonecrosis of the Femoral Head (ONFH) is a progressive disease characterized by the death of bone cells due to the loss of blood supply. Early detection and treatment of this disease are vital in avoiding Total Hip Replacement. Early stages of ONFH can be diagnosed using Magnetic Resonance Imaging (MRI), commonly used intra-operative imaging modalities such as fluoroscopy frequently fail to depict the lesion.

The Definition of Anemia Matters When Using Preoperative Hemoglobin as a Screening Tool Prior to Total Hip and Knee Arthroplasty.

Background: Preoperative anemia is common in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). Several definitions of anemia have been described, with no clear consensus on the optimal one for preoperative screening. We hypothesized that depending on the definition used preoperatively, the proportion of anemic patients identified who would require a postoperative allogeneic blood transfusion would vary significantly.

Knowledge of Healthcare Professionals on Hepatitis B Virus Infection and Vaccination Uptake in a Tertiary Hospital in Nigeria.

Background/objectives: Healthcare professionals (HCPs) play a key role in the prevention of hepatitis B virus (HBV) infection. HCPs are expected to have adequate basic knowledge of HBV and readily uptake HBV vaccination as they are a high-risk group, especially those that have direct contact with blood and/or blood products. This study was aimed at assessing the knowledge of and vaccination uptake of HBV among HCPs in a Nigerian tertiary hospital.

Publishing on Topical Subjects in Total Joint Arthroplasty Is Associated With Increased Social Media Attention.

Background: Social media platforms are often used for research dissemination and collaboration. Given the increased prevalence of online-only publications, understanding what drives research dissemination is important. Here, we analyzed factors associated with increased social media attention among peer-reviewed publications in total knee arthroplasty, total hip arthroplasty, and unicompartmental knee arthroplasty.
