Robotic-Arm Assisted THA: Improved Acetabular Component Accuracy and Patient-Reported Outcome Measures.

Introduction: Acetabular component placement is critical for total hip arthroplasty (THA) stability and clinical outcomes. We investigated cup placement with robotic-arm assisted (RA) and conventional manual (CM) THA and compared patient-reported outcome measures (PROMs) and dislocations.

Materials And Methods: Thirty-seven patients were randomized to undergo RA or CM primary THA.

A Pilot Study Using a Standardized Method of Measuring Distress Demonstrates Higher Levels in Septic Revisions.

Background: Combined Orthopaedic Infectious Disease Clinics facilitate care for prosthetic joint infection (PJI) patients similar to multidisciplinary care in cancer centers. The National Comprehensive Cancer Network developed a standardized distress thermometer (DT) to measure distress in cancer patients. We propose using this tool to assess distress in PJI patients.

ATV-Related Trauma in the Pediatric Population.

Background: All-terrain vehicles (ATVs) are prevalent in Appalachia and cause significant morbidity and mortality in the pediatric population. This study investigated the injury types and severity in pediatric patients over a 15-year period.

Methods: A retrospective chart review was performed on pediatric ATV-related traumas presenting to our institution from 2005 to 2020.

Matrix from urine stem cells boosts tissue-specific stem cell mediated functional cartilage reconstruction.

Articular cartilage has a limited capacity to self-heal once damaged. Tissue-specific stem cells are a solution for cartilage regeneration; however, expansion resulting in cell senescence remains a challenge as a large quantity of high-quality tissue-specific stem cells are needed for cartilage regeneration. Our previous report demonstrated that decellularized extracellular matrix (dECM) deposited by human synovium-derived stem cells (SDSCs), adipose-derived stem cells (ADSCs), urine-derived stem cells (UDSCs), or dermal fibroblasts (DFs) provided an solution to rejuvenate human SDSCs in proliferation and chondrogenic potential, particularly for dECM deposited by UDSCs.

Lower Extremity Fractures in Children: How to Avoid Pitfalls and Manage Complications.

One in three children in the United States will sustain a fracture before the age of 16 years, and nearly one of every four pediatric visits is for a lower extremity musculoskeletal complaint. Clinicians should be familiar with the epidemiology, management, and complications of pediatric pelvis, hip, femur, tibia, and ankle fractures.
