Assessment of the Learning Curve of Supercapsular Percutaneously-assisted Total Hip Arthroplasty in an Asian Population

Pengfei LeiChunhua Yang


Background: The supercapsularpercutaneously-assisted total hip (SuperPATH) approach is a micro-invasive approach that was developed to minimize surgical disruption of soft-tissue during routine total hip arthroplasty (THA). This study aimed to assess early outcomes and learning curves of the SuperPATHapproachin one Chinese hospital’s experience.Methods: Early outcomes of the first consecutive 78SuperPATH cases (80 hips) performed by same surgeon were evaluated. The patients were divided into 4 groups according to the surgical order. The incision, intraoperative blood loss, hospital stay, Harris hip score and complications occurrence in each group were evaluated. Learning curves were assessed using operative time and intraoperative blood loss as surrogates.Results:The operation time and intraoperative blood loss of group A and B was more than that of group C and D, and the difference was statistically significant (P<0.05), however there was no statistically significant difference between the two groups (group A vs. group B, P=0.426; group A vs. group B, P=0.426).There was no statistically significant difference in terms of incision length and hospital stay and Harris hip score at the last follow-up was increased with statisti...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response.
