Undergoing Meniscectomy Within One Year Before Primary Total Knee Arthroplasty Is Associated With Worse Postoperative Outcomes.

Background: Patients undergoing primary total knee arthroplasty (TKA) who have a history of meniscectomy have worse postoperative functional outcomes, increased rates of early postoperative complications, and higher revision rates. Despite knowing this, to the best of our knowledge, it has not been previously studied whether the timing of meniscectomy before TKA impacts functional outcomes after undergoing TKA. Compared to patients who underwent meniscectomy more than one year before TKA, do patients who have meniscectomy less than one year before TKA have significantly different postoperative outcomes?

Methods: A retrospective cohort study was conducted at an academic medical center.

Outcomes of Biodegradable Temporizing Matrix for Soft Tissue Reconstruction of the Hand and Extremities.

Background: NovoSorb biodegradable temporizing matrix (BTM) is a novel, bilayer, synthetic skin substitute made of biodegradable polyurethane foam covered with a sealing membrane. BTM has demonstrated excellent outcomes in burn literature; however, few studies have been published for hand and extremity soft tissue reconstruction.

Methods: All patients who underwent extremity reconstruction with BTM from 2018 to 2023 were reviewed.

Streamlining Iliac Bone Harvest for Maxillary Reconstruction With Novel Use of Arthrex Osteochondral Autograft Transfer System.

This study introduces a novel application of the Osteochondral Autograft Transfer System (OATS) for autologous bone grafting during alveolar cleft repair. Approximately 75% of patients with cleft lip and palate have an alveolar cleft, which often necessitates secondary bone grafting from common donor sites such as the iliac crest. Traditional harvesting techniques, although effective, can be labor-intensive and increase the risk of donor site injury.

Improving Skin Paddle Reliability and Muscle Gliding in Free Functional Gracilis Transfers.

Free functional muscle transfer is an attractive option within reconstructive surgery when seeking to restore critical muscle function. The gracilis muscle has long been utilized for this purpose due to its expendability and consistent anatomy. Historically, survival of the skin overlying the distal one-third of the myocutaneous gracilis flap has been unpredictable.

The effects of a multidisciplinary pathway for perioperative management of patients with hip fracture.

Objectives: To determine if a multidisciplinary pathway focused on non-opioid pain management, delirium assessment, and resource utilization improved outcomes in geriatric hip fracture patients. The goal was to reduce opioid usage, consultation not congruent with guidelines, and increase use of regional anesthesia to reduce delirium and improve outcomes.

Methods: An observational study was performed on hip fracture patients before and after the intervention.

Analgesic options for anterior approach to scoliosis repair: a scoping review.

Purpose: The ideal analgesic regimen for the anterior approach to scoliosis repair is not clearly defined. The purpose of the study was to summarize and identify gaps in the current literature specific to the anterior approach to scoliosis repair.

Methods: A scoping review was conducted in July 2022 utilizing PubMed, Cochrane, and Scopus databases guided by the PRISMA-ScR framework.

Asthma Prevalence among Athletes in an Urban Adolescent Population.

Objective: To identify individuals at risk of asthma by assessing the prevalence of asthma in an urban, athletic adolescent population using preparticipation physical evaluation (PPE) data.

Study Design: Using the Athlete Health Organization (AHO) PPE data from 2016 to 2019, asthma prevalence was collected by reported diagnosis in the history or physical. Chi-square tests and logistic regression were performed to characterize the relationship between asthma and social factors such as race, ethnicity, and income.

Image-Free Robotic-Assisted Total Knee Arthroplasty Results in Quicker Recovery but Equivalent One-Year Outcomes Compared to Conventional Total Knee Arthroplasty.

Background: Few studies have addressed whether robotic-assisted total knee arthroplasty (RA-TKA) significantly impacts functional outcomes. This study was conducted to determine whether image-free RA-TKA improves function compared to conventional total knee arthroplasty (C-TKA), performed without the utilization of robotics or navigation, using the Minimal Clinically Important Difference (MCID) and Patient Acceptable Symptom State (PASS) as measures of meaningful clinical improvement.

Methods: A multicenter propensity score-matched retrospective study was conducted of RA-TKA using an image-free robotic system and C-TKA cases at an average follow-up of 14 months (range, 12 months to 20 months).

Prior Meniscectomy in Patients Undergoing Primary Total Knee Arthroplasty is Associated With Worse Short-Term Outcomes.

Background: Patients undergoing total knee arthroplasty (TKA) who have prior meniscectomy may have increased rates of postoperative infection, arthrofibrosis, and revision. However, aside from an increased risk of complications, it is unclear whether prior meniscectomy impacts functional outcomes after TKA. This study was conducted to compare functional outcomes following TKA in patients who did and did not have a prior meniscectomy.

3 Cases of Superior Vena Cava Syndrome Following Percutaneous Right Ventricular Assist Device Placement.

We present 3 cases of superior vena cava (SVC) syndrome following percutaneous right ventricular assist device (RVAD) placement. Each case underscores the importance of early recognition of SVC syndrome in patients with percutaneous RVAD insertion via the internal jugular vein and calls for heightened awareness of device-associated complications.

Glycan repositioning of influenza hemagglutinin stem facilitates the elicitation of protective cross-group antibody responses.

The conserved hemagglutinin (HA) stem has been a focus of universal influenza vaccine efforts. Influenza A group 1 HA stem-nanoparticles have been demonstrated to confer heterosubtypic protection in animals; however, the protection does not extend to group 2 viruses, due in part to differences in glycosylation between group 1 and 2 stems. Here, we show that introducing the group 2 glycan at Asn38 to a group 1 stem-nanoparticle (gN38 variant) based on A/New Caledonia/20/99 (H1N1) broadens antibody responses to cross-react with group 2 HAs.
