Purpose: To describe the outcomes of patients undergoing hip arthroscopy for femoroacetabular impingement at a mean 12-year follow-up and to determine the risk factors for failure.

Study Design: Case-control study; Level of evidence, 3.

Palliative care is a viable option for frail elderly patients with neurocognitive disorders admitted for hip fractures.

Importance: Most patients presenting with a hip fracture regardless of their comorbidities are surgically treated. A growing body of research states that a certain type of elderly patient could benefit more from a palliative approach.

Objective: Identify the patient who would benefit most from a palliative care approach instead of a surgery.

Arthroscopic Subdeltoid Humeroplasty in the Beach-Chair Position for Reverse Hill-Sachs Lesions.

Reverse Hill-Sachs lesions (HSLs) often involve a greater percentage of the humeral head articular surface than posterior HSLs and frequently require surgical treatment in the setting of posterior shoulder instability. Multiple techniques have been described to treat these lesions depending on their size, acuity, and location. The (modified) McLaughlin procedure is widely used to treat smaller engaging lesions, whereas larger lesions involving a greater percentage of the humeral head articular surface require anatomic disimpaction, termed "humeroplasty.

Strategies to improve end-of-life decision-making and palliative care following hip fracture in frail older adults: a scoping review.

Background: Although surgery is the gold standard following a hip fracture, the potential for rehabilitation and survival rates are low in frail older patients. Some patients may derive more benefit from palliative care. The objectives of this review were to identify the available strategies to improve end-of-life decision-making and palliative care for frail patients with hip fractures and to synthetise their level of support.

Implication of polymerase recycling for nascent transcript quantification by live cell imaging.

Transcription enables the production of RNA from a DNA template. Due to the highly dynamic nature of transcription, live-cell imaging methods play a crucial role in measuring the kinetics of this process. For instance, transcriptional bursts have been visualized using fluorescent phage-coat proteins that associate tightly with messenger RNA (mRNA) stem loops formed on nascent transcripts.

Sleep Apnea is Not an Obstacle for Outpatient Hip and Knee Arthroplasty.

Background: Up to 25% of patients requiring hip or knee arthroplasty have sleep apnea (SA), and these patients have historically been excluded from outpatient programs. The objectives of this study were to evaluate same-day discharge failure as well as 30-day complications, readmissions, and unexpected visits.

Methods: A retrospective case-control study comparing patients who have and do not have SA matched for age, sex and arthroplasty type (total hip arthroplasty, total knee arthroplasty, unicompartimental knee arthroplasty) who underwent primary outpatient surgery between February 2019 and December 2022 in 2 academic hospitals was conducted.

Incidence of venous thromboembolism in pediatric orthopedics: A systematic review.

Backgrounds: Children undergoing orthopedic procedures often present numerous risk factors for thromboembolism. A recent survey, conducted by the Pediatric Orthopaedic Society of North America (POSNA), indicates that pediatric orthopedic surgeons are unaware of venous thromboembolism (VTE) prevention protocols and feel that certain procedures should require thromboprophylaxis. The aim of this systematic review was to properly assess the incidence of VTE in pediatric orthopedics.

Gait pattern analysis before and after periacetabular osteotomy in unilaterally affected dysplastic patients.

Background: Patients with acetabular dysplasia have an abnormal acetabular geometry which results in insufficient coverage of the femoral head. This coverage deficiency reduces contact surfaces within the joint, accelerating the wear of the articular cartilage and predisposing patients to early osteoarthritis. Periacetabular osteotomy is a surgical treatment of acetabular dysplasia that aims to reorient the acetabulum relative to the femoral head, increasing coverage.

The impact of Canadian-produced research on the global orthopedic literature: a bibliometric analysis.

Background: Little is known about the quality and impact of Canadian-produced research relative to that of other developed nations. The purpose of this study was to determine the contribution of Canadian authors to the orthopedic literature globally and nationally as well as Canada's research productivity in orthopedics. We hypothesized that Canada ranks among the most impactful countries in terms of orthopedic research productivity.

Lateral knee laxity increases the risk of excessive joint line obliquity after medial opening-wedge high tibial osteotomy.

Background: Medial opening-wedge high tibial osteotomy (HTO) is a well-recognized treatment for patient with varus knee osteoarthritis. Joint line obliquity has recently been suggested to negatively impact clinical outcomes following HTO, but little is known about what factors lead to increased joint line obliquity. The purpose of the current study was (1) to evaluate whether increased preoperative lateral knee laxity, represented by the joint line convergence angle, results in increased joint line obliquity in a consecutive series of patients treated with HTO and (2) to determine the effect of advanced arthritic changes on joint line obliquity.

Volar Locking Plating Compared to Conservative Treatment in Distal Radius Fractures in Elderly Patients (>60 years old): A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Purpose: We performed a systematic review and meta-analysis to compare the efficacy of volar locking plating (VLP) to conservative treatment in distal radius fractures in patients aged >60 years old.

Methods: English articles were searched in electronic databases including MEDLINE, CENTRAL, Embase, Web of science, and ClinicalTrial.gov from inception to October 2020.

Validation of the French version of the Non-Arthritic Hip Score (NAHS) in 113 hip arthroscopy procedures.

Background: The Non-Arthritic Hip Score (NAHS) used to evaluate the hip in younger patients is a self-administered questionnaire with 20 items in four sections: pain, symptoms, function, and activities. Although used in France, no transcultural version had been validated. The objective of this study was to translate the NAHS into French then assess the validity, reliability, and sensitivity to change of the French-language version (NAHS-Fr) in younger patients with hip conditions other than osteoarthritis.

Should We Use Bipolar Hemiarthroplasty in Patients ≥70 Years Old With a Femoral Neck Fracture? A Review of Literature and Meta-Analysis of Randomized Controlled Trials.

Background: Bipolar (BHA) and unipolar hemiarthroplasties (UHA) are interchangeably used in elderly patients with a displaced femoral neck fracture. We ask if there is a difference between BHA and UHA with regards to hip function, in elderly patients.

Methods: Systematic review and meta-analysis was conducted of randomized controlled trials comparing BHA to UHA.

The risk of venous thromboembolism in surgically treated hip fracture: A retrospective cohort study of 5184 patients.

Introduction: Elderly patients undergoing surgery for a hip fracture are at risk of venous thromboembolism (VTE). The known risk of VTE is low due to thromboprophylaxis (1.8-2.

Validation of the French version of the Self-Administered International Hip Outcome Tool-12 Questionnaire and determination of the Minimal Clinically Important Difference (MCID) in the French speaking population.

Background: Patient-Reported Outcomes tools are becoming the gold standard in the evaluation of results in orthopaedic surgery. In 2012, the International Hip Outcome Tool-12 (iHOT-12) was developed. This self-administered questionnaire was designed to address the day-to-day clinical setting with faster completion and easier patient flow.

Return to Baseline Physical Activity After Bone-Patellar Tendon-Bone Versus Hamstring Tendon Autografts for Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Background: Bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) autografts are the most utilized grafts for primary anterior cruciate ligament (ACL) reconstruction. The ability of a patient to return to a preinjury level of physical activity is a key consideration in choice of graft; the influence of graft choice on this metric lacks consensus in the literature.

Purpose: To assess the effects of autograft choice (BPTB vs HT) for primary ACL reconstruction on return to baseline level of physical activity and/or sports participation.
