Long-Term Patient Outcomes for Treatment of Difficult Osteochondral Lesions of the Talus with Particulated Juvenile Allograft Cartilage Implantation ± Calcaneal Autograft: A Cohort Study.

Background: Osteochondral lesions of the talus (OCLT) are common injuries that can be difficult to treat. To date, long-term patient reported outcome measures (PROMs) of patients with particulated juvenile allograft cartilage implantation with or without calcaneal autograft have not been compared.

Methods: Thirteen patients with difficult to treat OCLTs underwent arthroscopic-assisted implantation of particulated juvenile allograft cartilage (DeNovo NT®) with or without autogenous calcaneal bone grafting by a single surgeon.

A New Test for Trigger Finger: The Lenox Independent Flexion Test.

The diagnosis of trigger finger (TF) in patients who do not demonstrate triggering at presentation can be challenging. We have been using a new test for TF - the Lenox Independent Flexion Test (LIFT). The aim of this study is to determine the sensitivity of LIFT in diagnosing TF.

The Effect of the COVID-19 Pandemic on Orthopedic Practices in New York.

The SARS-CoV-2 (COVID-19) crisis has strained hospitals and health systems across the world. In the United States, New York City has faced a surge of cases as the epicenter of the North American outbreak. Northwell Health, as the largest regional health system in New York City, has implemented various practices and policies to adapt to the evolving situation and prepare for future global events.

The top 100 classic papers on adolescent idiopathic scoliosis in the past 25 years: a bibliometric analysis of the orthopaedic literature.

Study Design: Bibliometric analysis.

Objectives: To identify the 100 most cited orthopedic papers in adolescent idiopathic scoliosis (AIS) over the past 25 years and characterize them by study type, topic, and country and assess study quality (design, level of evidence, and impact factor) to provide an updated account of the most impactful AIS evidence. AIS represents a three-dimensional deformity that drives a significant number of investigations.

The Dubousset Functional Test is a Novel Assessment of Physical Function and Balance.

Background: Currently, the functional status of patients undergoing spine surgery is assessed with quality-of-life questionnaires, and a more objective and quantifiable assessment method is lacking. Dr. Jean Dubousset conceptually proposed a four-component functional test, but to our knowledge, reference values derived from asymptomatic individuals have not yet been reported, and these are needed to assess the test's clinical utility in patients with spinal deformities.

A Systematic Review and Meta-Analysis of Procalcitonin as a Marker of Postoperative Orthopedic Infections.

Procalcitonin is a serologic marker that increases in response to inflammatory stimuli, especially those of bacterial origin. Postoperative orthopedic periprosthetic infections are often difficult to diagnose. This study systematically reviewed the literature to evaluate the statistical measures of performance of procalcitonin as a marker of postoperative orthopedic infection.

Robotic-Assisted and Computer-Navigated Unicompartmental Knee Arthroplasties: A Systematic Review.

Introduction: Unicompartmental knee arthroplasty (UKA) effectively improves pain and function associated with isolated compartmental knee arthritis. The developments of computer-navigated and robotic-assisted UKA are among the most significant changes that have improved patient outcomes. This study aimed to systematically review the literature to identify differences between computer-navigated and robotic-assisted UKAs.

The Impact of Comorbid Mental Health Disorders on Complications Following Cervical Spine Surgery With Minimum 2-Year Surveillance.

Study Design: Retrospective analysis.

Objective: To improve understanding of the impact of comorbid mental health disorders (MHDs) on long-term outcomes following cervical spinal fusion in cervical radiculopathy (CR) or cervical myelopathy (CM) patients.

Summary Of Background Data: Subsets of patients with CR and CM have MHDs, and their impact on surgical complications is poorly understood.

The Impact of Comorbid Mental Health Disorders on Complications Following Adult Spinal Deformity Surgery With Minimum 2-Year Surveillance.

Study Design: Retrospective analysis.

Objective: To compare long-term outcomes between patients with and without mental health comorbidities who are undergoing surgery for adult spinal deformity (ASD).

Summary Of Background Data: Recent literature reveals that one in three patients admitted for surgical treatment for ASD has comorbid mental health disorder.

The Risks of Hepatitis C in Association With Cervical Spinal Surgery: Analysis of Radiculopathy and Myelopathy Patients.

Study Design: Retrospective review.

Objective: To investigate rates of in-hospital postsurgical complications among hepatitis C-infected patients after cervical spinal surgery in comparison with uninfected patients and determine independent risk factors.

Summary Of Background Data: Studying hepatitis C virus (HCV) as a possible risk factor for cervical spine postoperative complications is prudent, given the high prevalence of cervical spondylosis and HCV in older patients.

Adult Reconstruction Studies Presented at AAOS and AAHKS 2011-2015 Annual Meetings. Is There a Difference in Future Publication?

Background: The purpose of this study was to compare adult reconstruction abstracts presented at the American Academy of Orthopaedic Surgeons (AAOS) and the American Association of Hip and Knee Surgeons (AAHKS) annual meetings.

Methods: A total of 1355 podium and 1731 poster presentations from the adult reconstruction sections of the AAOS and AAHKS meetings from 2011 to 2015 were reviewed for publication in peer-reviewed literature. Authors who were added or removed from the original abstract and the final manuscript were recorded.

Does Preadmission Cutaneous Chlorhexidine Preparation Reduce Surgical Site Infections After Total Hip Arthroplasty?

Background: Periprosthetic hip infections are among the most catastrophic complications after total hip arthroplasty (THA). We had previously proven that the use of chlorhexidine cloths before surgery may help decrease these infections; hence, we increased the size of the previously reported cohort.

Questions/purposes: (1) Does a preadmission chlorhexidine cloth skin preparation protocol decrease the risk of surgical site infection in patients undergoing THA? (2) When stratified using the National Healthcare Safety Network (NHSN) risk categories, which categories are associated with risk reduction from the preadmission chlorhexidine preparation protocol?

Methods: Between 2007 and 2013, a group of 998 patients used chlorhexidine cloths before surgery, whereas a group of 2846 patients did not use them and underwent standard perioperative disinfection only.

The effects of velocity-spectrum training on the ability to rapidly step.

Falls may occur because of a deficiency in the ability to rapidly step in the desired direction. Previous models developed to predict rapid step ability have been based on balance, video analysis, or uniplanar isokinetic performance. The purpose of this investigation was to determine the effects of multiplanar velocity-spectrum training of the hip.

Effects of velocity-specific training on rate of velocity development, peak torque, and performance.

Little is known about the velocity-specific adaptations to training utilizing movement velocities in excess of 300 degrees x s(-1). The purpose of this investigation was to determine the effects of 4 weeks of slow (60 degrees x s(-1)) vs. fast (400 degrees x s(-1)) velocity training on rate of velocity development (RVD), peak torque (PT), and performance.

The influence of body position on load range during isokinetic knee extension/flexion.

rate of velocity development (RVD), load range (LR), and deceleration (DCC). The purpose of this study was to determine if differences in isokinetic knee extension/flexion LR exist between body positions. Ten subjects (4 males and 6 females, age 29.
