Introduction: Notchplasty is an adjuvant procedure performed during Anterior Cruciate Ligament reconstruction (ACLR) with the purpose of widening the intercondylar notch of the femur. Its use is controversial due to its biomechanical influence on the knee and the potential for increased complications. The purpose of this systematic review is to evaluate the outcomes of patients who underwent ACLR with notchplasty.

Materials And Methods: A systematic search of Cochrane, Embase, and Medline was conducted to identify papers evaluating clinical outcomes of patients who underwent ACLR with notchplasty. Inclusion criteria encompassed human studies with a control group, reporting clinical outcomes such as graft failure, graft rupture, range of motion values, and patient-reported outcomes.

Results: A total of 4 studies were included comprising 396 patients (129 with notchplasty, 235 without). No significant differences were reported regarding graft survivability or Lysholm score between those with notchplasty and those without. One study reported significantly reduced rates of revision surgery after ACLR with notchplasty. There were conflicting complication rates between studies regarding chronic synovitis and arthrofibrosis.

Conclusion: Patients who undergo notchplasty during primary ACLR have similar outcome scores and risk of graft failure compared to those who do not undergo notchplasty. Notchplasty patients may also be at a higher risk for loss of extension and chronic synovitis.

Objective: Evaluate Department of Defense (DoD) antimicrobial stewardship programs (ASPs) by assessing the relationship between key clinical outcome metrics (antibiotic use, incidence of resistant pathogens, and incidence of infections) and CDC Core Element (CE) adherence.

Design: Retrospective, cross-sectional study of DoD hospitals in 2018 and 2021.

Methods: National Healthcare Safety Network Standardized Antimicrobial Administration Ratios (SAARs) were used to measure antibiotic use and microbiology results to evaluate four types of pathogen incidence.

Background And Aims: Better understanding the challenges faced by patients on medications for opioid use disorder (MOUD), including methadone and buprenorphine, is critical to increasing their use/retention. Social media platforms such as Reddit offer a space for patients to share their experiences with medications. We aimed to identify and characterize challenges faced by patients taking MOUD through analysis of discussions from the r/Methadone and r/suboxone subreddits.

Purpose: To evaluate and contrast the effectiveness and safety of two conbercept treatment protocols-a three-dose treat-and-extend (3+T&E) regimen and a three-dose pro re nata (3+PRN) regimen-in Chinese patients diagnosed with neovascular age-related macular degeneration (nAMD).

Methods: Eligible patients, who had not undergone anti-VEGF intraocular injections within 3 months prior to enrollment, were randomly assigned to either the 3+T&E or 3+PRN regimen. The 3+T&E group received at least three monthly injections, with subsequent visit intervals extended based on disease activity assessment.

Role of Perivascular Adipose Tissue in Vein Remodeling.

Arterioscler Thromb Vasc Biol

March 2025

Department of Surgery, Leiden University Medical Center, the Netherlands. (N.K., T.J.S., M.R.d.V.).

Perivascular adipose tissue (PVAT) plays a crucial, yet underexplored, role in vein remodeling, which occurs after bypass surgery using a venous graft or creation of arteriovenous fistulae for hemodialysis access. PVAT exhibits significant heterogeneity in phenotype and tissue composition depending on the vascular bed, as well as its anatomic location within the vasculature. Through the excretion of adipokines, cytokines, and chemokines, PVAT can shape the vascular response to local and systemic perturbations.
