Four Analyses Yield Wealth of Information on Femoral Neck Fixation Based on AJRR Data

Mita De, PhD; Terry Stanton

Reflecting the continuing growth and success of the AAOS Registry Program, this year’s Annual Meeting has been a forum for an unprecedented number of studies related to data collected within the entire portfolio of registries.

Study Gauges 1D, 2D, and 3D Weight-bearing CT to Diagnose Syndesmotic Instability

Terry Stanton

A study presented Wednesday aimed to evaluate the ability of weight-bearing computed tomography to diagnose syndesmotic instability using 1D, 2D, and 3D measurements among patients with unilateral Weber B lateral malleolar ankle fractures. The patients in the study did not demonstrate widened medial clear space on initial radiographs yet demonstrated operatively confirmed syndesmotic instability.

Sensor-guided Ligament Balancing in TKA Does Not Improve Short-term Outcomes versus Freehand Technique

Rebecca Araujo

In a randomized, controlled trial, sensor-guided ligament balancing during total knee arthroplasty (TKA) was found to be noninferior to freehand balancing but did not lead to improvements in short-term postoperative function or outcomes.

Geographic Variability Seen in Medicare Reimbursement for Joint Replacement

Rebecca Araujo

A study of changes in Medicare reimbursement for arthroplasty procedures in the United States since 2000 found large geographic variability arising over that period.

Study Probes Role of Depression in Recovery from Ankle Fracture

Terry Stanton

A study exploring the role of depression in functional and pain outcomes for patients treated for an isolated ankle fracture found that all patients have postoperative improvement, but those with no or low-level depressive symptoms improve to a greater extent.

Articular Cartilage Injury with Recurrent Patellar Dislocation Is Common, Progresses Quickly

Ariel DeMaio

Nearly half of patients undergoing patellar stabilization surgery for recurrent patellar dislocation experienced articular cartilage injury, according to results from an MRI study of 35 patients.

Model Predicts Two-year Functional Outcomes after Shoulder Replacement

Rebecca Araujo

Using a new model incorporating patients’ preoperative characteristics, clinicians were able to predict postoperative pain and functional outcomes after total shoulder arthroplasty (TSA), according to results of a pooled analysis from three high-volume centers.

Football, Women’s Volleyball Lead Team Sports in Concussion Injuries

Ariel DeMaio

In an analysis of 17 years of data from the University of Southern California, researchers described the timing, frequency, and recovery patterns of concussion among NCAA Division 1 athletes.

Outpatient TJAs Performed at ASCs Are Associated with Lower Costs, Admission Rates Than Those Performed at HOPDs

Ariel DeMaio

The type of facility where an outpatient total joint arthroplasty (TJA) is performed significantly impacts outcomes, complications, and costs associated with the procedure, according to an analysis that appeared to favor performing TJAs at ambulatory surgical centers (ASCs) over hospital outpatient departments (HOPDs).

Machine Learning Models May Predict Improvements after TSA for Glenohumeral OA

Rebecca Araujo

Machine learning–based models may accurately predict improvement in American Shoulder and Elbow Surgeons (ASES) scores after total shoulder arthroplasty (TSA) for glenohumeral osteoarthritis (GHOA), according to a poster study on display today and tomorrow in Academy Hall.

Study Ranks Medical Schools with the Greatest Number of Black Graduates Matched into Orthopaedic Surgery Residencies

Ariel DeMaio

The historically Black colleges and universities Howard University and Meharry Medical College have produced the highest number of Black medical students who successfully matched into orthopaedic residency programs, according to an analysis of an academic database.

Extended Oral Antibiotic Prophylaxis Protocol Is a Cost-effective Tool for Preventing PJI

Ariel DeMaio

Periprosthetic joint infection (PJI) is a dreaded complication after total knee arthroplasty (TKA) and total hip arthroplasty (THA), particularly for high-risk patients who have increased susceptibility to infection.

More than Half of Opioids Prescribed to Young Patients After Surgery Go Unused

Ariel DeMaio

Adolescents undergoing orthopaedic surgery are commonly prescribed opioid medications for postoperative pain management, but few pediatric patients actually consume the full amount of tablets or liquid doses prescribed, according to a study conducted at Children’s Healthcare of Atlanta.

Use of Intraoperative Neuromonitoring during Spine Surgery Varies Widely

Rebecca Araujo

A survey of spine surgeons found that use of intraoperative neuromonitoring (IONM) during spine surgery varied depending on the surgical indication.
