Does robotic arm-assisted total knee arthroplasty have a role to play in large deformities?

Background: Total knee arthroplasty (TKA) for patients with a large preoperative deformity (more than 10° varus or valgus) remains a challenge leading to a high rate of outliers, unsatisfactory functional results, or early prosthetic loosening. Robotic arm-assisted TKA (RATKA) has shown improvements in implant positioning accuracy. This study aimed to assess RATKA implant positioning accuracy and functional results at one year postoperative for patients with a large preoperative deformity.

Oblique or short incisions reduce the risk of saphenous nerve damage during hamstrings harvesting: A model for mapping nerve pathways at the harvest site.

Introduction: Hamstring autografts are frequently used for ligament reconstruction surgery. Between 12% and 84% of patients report hypoesthesia or dysaesthesia secondary to injury of the saphenous nerve or one of its branches after hamstring harvesting. Type of incision (orientation and length) is subject of much regarding limiting the risk of nerve damage.

Extracellular Vesicles Induce Nuclear Factor-κB Activation and Interleukin-8 Synthesis through miRNA-191-5p Contributing to Inflammatory Processes: Potential Implications in the Pathogenesis of Chronic Obstructive Pulmonary Disease.

Extracellular vesicles (EVs) play a pivotal role in a variety of physiologically relevant processes, including lung inflammation. Recent attention has been directed toward EV-derived microRNAs (miRNAs), such as miR-191-5p, particularly in the context of inflammation. Here, we investigated the impact of miR-191-5p-enriched EVs on the activation of NF-κB and the expression of molecules associated with inflammation such as interleukin-8 (IL-8).

Isolated posterior stabilization in type B and C thoracolumbar fractures associated with ankylosing spine disorders: A single center experience with clinical and radiological outcomes.

Introduction: Fractures in ankylosing spine disorders (ASD) are associated with high complication and mortality rates. During the posterior stabilization of these fractures, reduction is often partial, resulting in the persistence of a significant anterior diastasis. Our objective was to evaluate the safety and efficiency of isolated posterior stabilization in elderly ASD patients, without direct reduction of the anterior diastasis, in terms of clinical and radiological outcomes, complications, and mortality.
