Journal ArticleDOI
The Anterolateral Capsule of the Knee Behaves Like a Sheet of Fibrous Tissue
Daniel Guenther,Daniel Guenther,Amir Ata Rahnemai-Azar,Kevin M. Bell,Sebastián Irarrázaval,Freddie H. Fu,Volker Musahl,Richard E. Debski +7 more
TL;DR: The anterolateral capsule carries negligible forces in the longitudinal direction, and the forces transmitted between regions of the capsule were similar to the forces carried by the other structures at the knee, suggesting that it does not function as a traditional ligament.
Journal ArticleDOI
Oxidative Stress in Acute Hypobaric Hypoxia.
Sebastián Irarrázaval,Claudio Allard,Juan Campodónico,Druso Pérez,Pablo Strobel,Luis Vasquez,Inés Urquiaga,Guadalupe Echeverría,Federico Leighton +8 more
TL;DR: Acute hypobaric hypoxia induced AMS and an increment in oxidative stress markers 24 hours after altitude exposure in the volunteers, and oxidative stress damage was related to AMS severity.
Journal ArticleDOI
Variation in the shape of the tibial insertion site of the anterior cruciate ligament: classification is required
Daniel Guenther,Daniel Guenther,Sebastián Irarrázaval,Yuichiro Nishizawa,Cara Vernacchia,Eric Thorhauer,Volker Musahl,James J. Irrgang,Freddie H. Fu +8 more
TL;DR: The classification system is a repeatable and reliable tool to summarize the shape of the TIS using three common patterns and consideration of the individual TIS shape is required to prevent iatrogenic damage of adjacent structures like the menisci.
Journal ArticleDOI
The Role of Extra-Articular Tenodesis in Combined ACL and Anterolateral Capsular Injury.
Daniel Guenther,Sebastián Irarrázaval,Kevin M. Bell,Amir Ata Rahnemai-Azar,Freddie H. Fu,Richard E. Debski,Volker Musahl +6 more
TL;DR: In this study, an extra-articular tenodesis was necessary to restore rotatory knee stability in response to internal tibial torque in a combined ACL and anterolateral capsule-deficient knee.
Journal ArticleDOI
Anatomical Individualized ACL Reconstruction.
TL;DR: Using this concept, while single bundle ACL reconstruction can restore the function of the ACL in some patients, double bundle reconstruction is indicated in others to achieve optimal outcome.
