Midterm results for revision total knee arthroplasty for component malrotation.

Introduction: Accurate positioning of components in total knee arthroplasty (TKA) is essential to a satisfactory outcome. Significant malrotation may lead to chronic pain, stiffness, and dysfunction. This study aims to quantify improvements in functional outcomes following revision surgery for malrotation of either one or both components in TKA versus revision for aseptic loosening.

Complications and Survivorship After Aseptic Revision Total Hip Arthroplasty: Is There a Difference by Surgical Approach?

Background: Revision total hip arthroplasty (rTHA) has traditionally been performed through the posterolateral approach (PA). Anterior approaches (AA) for rTHA are increasingly being utilized. The purpose of this study was to compare complications and survivorship from re-revision and reoperation after aseptic rTHA performed using an AA versus a PA.

Specific Preoperative Factors Increase Manipulations under Anesthesia Following Primary TKA.

Arthrofibrosis following primary total knee arthroplasty (TKA) can result in pain and limit postoperative range of motion (ROM), jeopardizing clinical outcomes and patient satisfaction. This study aims to identify preoperative risk factors associated with necessitating a manipulation under anesthesia (MUA) following primary TKA.We retrospectively reviewed 950 cases of consecutive primary TKAs performed at one institution by three arthroplasty surgeons between May 2017 and May 2019.

Preoperative Fascia Iliaca Blocks Associated With Decreased Opioid Consumption in Femoral Shaft and Distal Femur Fractures.

Objectives: To examine the impact of fascia iliaca (FI) blocks performed in the emergency department on femoral shaft and distal femur fracture patients on opioid consumption, length of stay (LOS), and readmission rate.

Design: Prospective cohort study.

Setting: Community-based Level 1 trauma center.

Large-scale Implementation of Fascia Iliaca Compartment Blocks in an Emergency Department.

Introduction: A robust body of literature supports the use of fascia iliaca compartment blocks (FICB) for improving outcomes in hip fractures, especially in the geriatric population. Our objective in this project was to implement consistent pre-surgical, emergency department (ED) FICB for hip fracture patients and to address barriers to implementation.

Methods: With the support of a multidisciplinary team, including orthopedic surgery and anesthesia, a core team of emergency physicians developed and implemented a departmentwide FICB training and credentialing program.

Early hip fracture surgery is safe for patients on direct oral anticoagulants.

Objectives: To determine how preoperative direct oral anticoagulant (DOAC) use affects rates of blood transfusion, clinically important blood loss, and 30-day mortality in patients with hip fracture undergoing surgery within 48 hours of presentation to the emergency department.

Design: Retrospective cohort study.

Setting: Academic trauma center.

Handheld Navigation Improves Accuracy in Direct Anterior Total Hip Replacement.

Background: This study sought to determine the accuracy in placing the acetabular component, estimation of leg length, offset, radiation time and dose, and operative time using a handheld navigation device compared to conventional anterior total hip arthroplasty (THA). It also examined the learning curve of the handheld navigation device.

Methods: Data were prospectively collected for a consecutive series of 159 THAs; 99 THAs with handheld navigation and 60 conventional THAs.

Comparison of Self-reported Versus Actual Height and Weight in the Orthopaedic Population.

The purpose of our study was to determine the accuracy of orthopaedic patient's reported height, weight, and body mass index (BMI). We hypothesized that patient's age, sex and/or BMI may affect their accuracy. We performed a prospective, observational study in the setting of our orthopaedic clinic.

Fascia Iliaca Blocks Performed in the Emergency Department Decrease Opioid Consumption and Length of Stay in Patients with Hip Fracture.

Objectives: To examine the impact of fascia iliaca (FI) blocks performed in the emergency department on patients with hip fracture on opioid consumption, length of stay, and readmission rate.

Design: Prospective cohort study.

Setting: Community-based Level 1 trauma center.

Can robotic technology mitigate the learning curve of total hip arthroplasty?

Aims: Traditionally, acetabular component insertion during total hip arthroplasty (THA) is visually assisted in the posterior approach and fluoroscopically assisted in the anterior approach. The present study examined the accuracy of a new surgeon during anterior (NSA) and posterior (NSP) THA using robotic arm-assisted technology compared to two experienced surgeons using traditional methods.

Methods: Prospectively collected data was reviewed for 120 patients at two institutions.

Prior Admissions as a Risk Factor for Readmission in Patients Surgically Treated for Femur Fractures: Implications for a Potential Hip Fracture Bundle.

Introduction: Hip fractures are a significant economic burden to our healthcare system. As there have been efforts made to create an alternative payment model for hip fracture care, it will be imperative to risk-stratify reimbursement for these medically comorbid patients. We hypothesized that patients readmitted to the hospital within 90 days would be more likely to have a recent previous hospital admission, prior to their injury.

Prospective Evaluation of a Noninvasive Hemoglobin Measurement System in Total Joint Arthroplasty.

We sought to prospectively determine the efficacy of a noninvasive hemoglobin measurement system compared to a traditional blood draw in patients undergoing total joint arthroplasty. One hundred consecutive patients had their hemoglobin level measured by blood draw and the noninvasive device, simultaneously. Results were analyzed for the entire group and further stratified based on race and perfusion index measured by the device.

Web-based patient portal access in an orthopedic adult reconstruction patient population.

Background: We surveyed patients in an adult reconstruction practice as to their use of the Web-based portal provided by our electronic health record, seeking to reveal patterns of use and helpfulness.

Methods: A total of 150 completed surveys were received. The survey queried demographics, the number of clinic visits, Internet access, portal activation, portal use frequency, and portal information questions and how patients answered them.

YouTube is a poor source of patient information for knee arthroplasty and knee osteoarthritis.

Background: The objective of this study was to assess the educational quality of YouTube videos pertaining to total knee arthroplasty and knee osteoarthritis.

Methods: A systematic search for the terms "knee replacement" and "knee arthritis" was performed using YouTube's search function. Data from the 60 most relevant videos were collected for each search term.

Patellofemoral Arthroplasty.

Background: Patellofemoral arthritis is a common cause of anterior knee pain and limits flexion-related activities of daily living and exercise. While frequently present in bicompartmental and tricompartmental osteoarthritis, patellofemoral arthritis can occur in isolation. Patellofemoral arthroplasty as a treatment option is gaining in popularity, especially with new implant designs.
