The Preoperative Patient-Reported Outcomes Measurement Information System (PROMIS)-10 Global Mental Health T-Score: An Independent Predictor of Immediate Postsurgical Outcomes Following Elective Total Knee Arthroplasty.

Background: Mental illness is a known risk factor for poor postoperative outcomes following total knee arthroplasty (TKA); however, a diagnosed mental illness does not always reflect the current state of a patient's mental health. Using the preoperative Patient-Reported Outcomes Measurement Information System-10 Mental Health T-score (MHT), the purpose of this study was to understand the association between mental health and a patient's immediate inpatient recovery pattern following TKA.

Methods: This was a retrospective study of patients undergoing elective primary TKA.

Tranexamic Acid Reduces the Amount of Blood Transfused in Revision Total Hip Arthroplasty for Vancouver B2/B3 Periprosthetic Femur Fractures.

Background: Periprosthetic fractures around total hip arthroplasty (THA) represent a significant source of morbidity and mortality. The use of tranexamic acid (TXA) in arthroplasty is well described, yet little literature supports its role in periprosthetic femur fractures (PFFs). This study investigated the effect of preoperative TXA administration on transfusion rate and volume, length of stay, and 90-day complication rates in patients undergoing revision THA for PFF.

Increasing Body Mass Index Not Associated With Worse Patient-Reported Outcomes After Primary THA or TKA.

Introduction: As the US obesity epidemic continues to grow, so too does comorbid hip and knee arthritis. Strict body mass index (BMI) cutoffs for total hip and knee arthroplasty (THA and TKA) in the morbidly obese have been proposed and remain controversial, although current American Academy of Orthopaedic Surgeons guidelines recommend a BMI of less than 40 m/kg 2 before surgery. This study sought to compare patient-reported outcomes and 30-day complication, readmission, and revision surgery rates after THA or TKA between morbidly obese patients and nonmorbidly obese control subjects.

Preoperative Bladder Scanning Can Predict Postoperative Urinary Retention Following Total Joint Arthroplasty.

Background: As total joint arthroplasty (TJA) moves to the outpatient setting, it is becoming clear that postoperative urinary retention (POUR) is a potential impediment to same-day discharge. Although risk factors for POUR have been widely studied, the lack of their clinical utility warrants investigation of specific preoperative factors that can assist in surgical planning and patient optimization. The purpose of the current study was to determine whether preoperative symptom surveys and bladder scanning are useful tools in identifying POUR risk.

Preoperative Factors to Assess Risk for Postoperative Urinary Retention in Total Joint Arthroplasty: A Retrospective Analysis.

Background: Postoperative urinary retention (POUR) is a significant problem in total joint arthroplasty (TJA). Although risk factors for POUR have been well documented, they are ubiquitous in an aging total joint population, which makes risk stratification difficult. The purpose of this study was to determine if a high preoperative post-void bladder scan identifies patients at risk for POUR.

Femoral Intramedullary Alignment in Total Knee Arthroplasty: Indications, Results, Pitfalls, Alternatives, and Controversies.

While femoral intramedullary alignment has been found to be the most accurate and reproducible method for proper femoral component orientation in total knee arthroplasty, certain situations preclude the use of intramedullary alignment, such as ipsilateral long-stem total hip arthroplasty, femoral shaft deformity (congenital or post-traumatic), capacious femoral canal, and retained hardware. These cases require alternative alignment guides, that is, extramedullary alignment. The purpose of this study was to determine the accuracy of intramedullary alignment in reproducing the femoral anatomic axis.
