Primary Anterior Cruciate Ligament Repair Using Suture Tape Augmentation: A Case Series of 29 Patients With Minimum 2-Year Follow-Up.

Purpose: To evaluate clinical outcomes and patient-reported outcomes of patients who underwent primary anterior cruciate ligament (ACL) repair using suture tape augmentation.

Methods: Patients with a proximal tear of the ACL who underwent primary ACL repair with a minimum 2-year follow-up were included. The exclusion criteria included multiligamentous knee injuries, midsubstance tears, tibial avulsion fractures, and distal tears.

Sagittal spinopelvic changes after posterior spinal fusion in adolescent idiopathic scoliosis.

Purpose: This article examines if longer posterior spinal fusions with instrumentation (PSFI) into the lumbar spine (L3/4) alter spinopelvic parameters compared with selective fusions to T12/L1/L2 in adolescent idiopathic scoliosis (AIS) patients.

Methods: We analysed radiographs of 84 AIS patients, 58 (69%) females and 26 (31%) males, who underwent PSFI at an mean age of 15 years ± 2.5 years, range 10 years to 21 years, between 1st January 2007 and 31st December 2014.

EphA7 isoforms differentially regulate cortical dendrite development.

The shape of a neuron facilitates its functionality within neural circuits. Dendrites integrate incoming signals from axons, receiving excitatory input onto small protrusions called dendritic spines. Therefore, understanding dendritic growth and development is fundamental for discerning neural function.

Ultrasound elastography of the patellar tendon in young, asymptomatic sedentary and moderately active individuals.

Background: The recent use of ultrasound elastography to study patellar tendon softness has demonstrated increased tendon softness in high-level athletes. We hypothesized that measurable alterations in patellar tendon softness may be present in young asymptomatic subjects engaging in moderate levels of physical activity.

Methods: This was a cross-sectional study.

Do Professional Society Advocacy Campaigns Have an Impact on Pediatric Orthopaedic Injuries?

Purpose: The American Academy of Orthopaedic Surgeons (AAOS) and the American Academy of Pediatrics (AAP) both advocate for childhood injury prevention by publishing recommendations to orthopaedic surgeons, pediatricians, and the public. Popular topics of advocacy campaigns have included trampolines, all-terrain vehicles (ATVs), and lawnmowers. The purpose of this study was to investigate the temporal relationship between AAOS/AAP advocacy and pediatric orthopaedic injury rates, using these topics as examples.

Spinal fusion surgery: A historical perspective.

The vast majority of technological advances in spinal fusion surgery have occurred within the past 50 years. Despite this, there existed a rich history of innovation, ingenuity, and resourcefulness among the spine surgeons of centuries before. Here, we pay tribute to this history, highlighting the important characters, their devices, and their thoughts, as they sought to alleviate human suffering from spinal deformity.

E-learning in orthopedic surgery training: A systematic review.

E-learning is the use of internet-based resources in education. In the field of surgical education, this definition includes the use of virtual patient cases, digital modeling, online tutorials, as well as video recordings of surgical procedures and lectures. In recent years, e-learning has increasingly been considered a viable alternative to traditional teaching within a number of surgical fields.

EphA7 signaling guides cortical dendritic development and spine maturation.

The process by which excitatory neurons are generated and mature during the development of the cerebral cortex occurs in a stereotyped manner; coordinated neuronal birth, migration, and differentiation during embryonic and early postnatal life are prerequisites for selective synaptic connections that mediate meaningful neurotransmission in maturity. Normal cortical function depends upon the proper elaboration of neurons, including the initial extension of cellular processes that lead to the formation of axons and dendrites and the subsequent maturation of synapses. Here, we examine the role of cell-based signaling via the receptor tyrosine kinase EphA7 in guiding the extension and maturation of cortical dendrites.
