Effect of Patient Age on Total Hip Arthroplasty Outcomes in Patients Who Have Osteonecrosis of the Femoral Head Compared to Patients Who Have Hip Osteoarthritis.

Background: Osteonecrosis of the femoral head (ONFH) affects both young and old patients. However, outcomes following total hip arthroplasty (THA) for these patients may vary with age. This study aimed to examine the effect of age on THA outcomes for non-traumatic ONFH patients, an area currently lacking research.

The Pregnant Arthroplasty Surgeon: A Women in Arthroplasty Committee Editorial.

Background: Women orthopaedic surgeons face unique challenges during their careers. There are extremely low numbers of women in the field, particularly in the specialty of adult reconstruction. Factors contributing to low numbers of women entering this subspecialty include increased perceived physical demand relative to other fields, occupational hazards during pregnancy such as exposure to radiation and polymethylmethacrylate bone cement, concerns for work-life balance, and limited number of women within the subspecialty.

Trends in Surgical Management of Osteonecrosis of the Femoral Head: A 2010 to 2020 Nationwide Study.

Background: The incidence of osteonecrosis of the femoral head (ONFH) is estimated at more than 20,000 patients annually in the US. Our study aimed to provide a 10-year analysis: 1) evaluating total operative procedures with rates normalized to the population; 2) determining trends of arthroplasty versus joint-preserving procedures; and 3) quantifying specific operative techniques in patients <50 versus >50 years of age.

Methods: A total of 64,739 patients who were diagnosed with ONFH and underwent hip surgery were identified from a nationwide database between 2010 and 2020.

Development of a personalized shared decision-making tool for knee osteoarthritis and user-testing with African American and Latina women.

Background: Patients with chronic knee pain are often unaware of treatment options and likely outcomes-information that is critical to decision-making. A consistent framework for communicating patient-personalized information enables clinicians to provide consistent, targeted, and relevant information. Our objective was to user-test a shared decision-making (SDM) tool for chronic knee pain.

Patients' experiences and compliance with preoperative screening and decolonization.

Background: To improve adherence with pre-surgical screening for Staphylococcus aureus nasal carriage and decolonization, we need more information about patients' experiences with these protocols.

Methods: We surveyed patients undergoing orthopedic, neurosurgical, or cardiac operations at Johns Hopkins Hospitals (JHH), the University of Iowa Hospitals and Clinics (UIHC) at MercyOne Northeast Iowa Neurosurgery (MONIN) to assess patients' experiences with decolonization protocols.

Results: Five hundred thirty-four patients responded.

Movement is Life-Optimizing Patient Access to Total Joint Arthroplasty: Smoking Cessation Disparities.

Currently, 13.7% of the adult American population smokes cigarettes. Although rates of cigarette smoking have decreased over time, those of e-cigarette usage have increased.

The 2021 Association Research Circulation Osseous Classification for Early-Stage Osteonecrosis of the Femoral Head to Computed Tomography-Based Study.

Background: The Association Research Circulation Osseous developed a novel classification for early-stage (precollapse) osteonecrosis of the femoral head (ONFH). We hypothesized that the novel classification is more reliable and valid when compared to previous 3 classifications: Steinberg, modified Kerboul, and Japanese Investigation Committee classifications.

Methods: In the novel classification, necrotic lesions were classified into 3 types: type 1 is a small lesion, where the lateral necrotic margin is medial to the femoral head apex; type 2 is a medium-sized lesion, with the lateral necrotic margin being between the femoral head apex and the lateral acetabular edge; and type 3 is a large lesion, which extends outside the lateral acetabular edge.

Movement Is Life-Optimizing Patient Access to Total Joint Arthroplasty: Dental Health Disparities.

Poor oral health is common in the United States; however, it is much more common in African Americans, Hispanics, and other racial/ethnic minorities. Almost one in five low-income adults states that their mouth and teeth are in poor condition. Twenty-nine percent of Americans have no dental insurance.

Osteonecrosis of the Femoral Head: an Updated Review of ARCO on Pathogenesis, Staging and Treatment.

Non-traumatic osteonecrosis of the femoral head (ONFH) usually affects adults younger than 50 years and frequently leads to femoral head collapse and subsequent arthritis of the hip. It is becoming more prevalent along with increasing use of corticosteroids for the adjuvant therapy of leukemia and other myelogenous diseases as well as management of organ transplantation. This review updated knowledge on the pathogenesis, classification criteria, staging system, and treatment of ONFH.

Diagnosis and Treatment of Femoral Head Osteonecrosis: A Protocol for Development of Evidence-Based Clinical Practice Guidelines.

Introduction: There are many treatment options for patients who have osteonecrosis of the femoral head (ONFH) and management strategies vary widely both among and within individual countries. Although many researchers have attempted to elucidate the optimal strategies for managing this disease, the lack of large-scale randomized control trials and the lack of agreement on disease staging have curtailed the development of clear-cut guidelines.

Materials And Methods: The Association Research Circulation Osseous (ARCO) group sought to address three questions for the management of patients who have ONFH: 1) What imaging studies are most sensitive and specific for the diagnostic evaluation of patients who have ONFH?; 2) What is the best treatment strategy for preventing disease progression in patients who have pre-collapse lesions?; and 3) What is the best treatment strategy for patients who have post-collapse disease? The Patient, Intervention, Comparison, and Outcome (PICO) format was used to formulate the search strategy for each research question.

ARCO Consensus on the Pathogenesis of Non-traumatic Osteonecrosis of the Femoral Head.

Osteonecrosis of the femoral head (ONFH) is a devastating disease frequently leading to femoral head collapse and hip arthritis. Specifically, non-traumatic ONFH primarily affects young and middle-aged adults. Although compromised local circulation of the femoral head seems to be pathognomonic for the disease, the pathogenesis is perplexing and continues to be an area of scrutiny and research.

Characterization of knee dysfunction and related risk factors during pregnancy.

Background: Knee pain can be a common complaint during pregnancy; however, the severity of symptoms and their associated risk factors have not been described.

Questions/purposes: The aim of this study was to characterize knee-related dysfunction and describe risk factors in a general obstetric population.

Patients And Methods: Patients in obstetric clinics completed the International Knee Documentation Committee (IKDC) questionnaire to assess their knee function, as well as the Pregnancy Physical Activity Questionnaire (PPAQ), a validated tool to assess physical activity.

Perception of Risk: A Poll of American Association of Hip and Knee Surgeons Members.

Background: Providers of total hip and knee replacements are being judged regarding quality/cost by payers using competition-based performance measures with poor medical and no socioeconomic risk adjustment. Providers might assume that other providers shed risk and the perception of added risk can influence practice. A poll was collected to examine such perceptions.

Changes in U.S. girls' participation in high school sports: implications for injury awareness.

Context: The number of female athletes has grown exponentially since Title IX. However, little data exists on the proportion of women and girls who play each sport.

Objective: To quantify changes in female sports participation in high school sports from 1973 to 2018.

Team approach: Management of osteonecrosis in children with acute lymphoblastic leukemia.

With current treatments for acute lymphoblastic leukemia (ALL), the overall prognosis for survival is favorable. Increasing emphasis is placed on recognizing and managing the long-term consequences of ALL and its treatment, particularly involving osteonecrosis. Early osteonecrosis diagnosis and management may improve outcomes and is best accomplished through coordinated teams that may include hematologic oncologists, radiologists, orthopedic surgeons, physical therapists, and the patient and their family.

Management of osteonecrosis of the femoral head.

Aims: Earlier studies dealing with trends in the management of osteonecrosis of the femoral head (ONFH) identified an increasing rate of total hip arthroplasties (THAs) and a decreasing rate of joint-preserving procedures between 1992 and 2008. In an effort to assess new trends in the management of this condition, this study evaluated the annual trends of joint-preserving versus arthroplasties for patients aged < or > 50 years old, and the incidence of specific operative management techniques.

Methods: A total of 219,371 patients with ONFH were identified from a nationwide database between 1 January 2009 and 31 December 2015.
