Changes in ACL T2* Metrics Over the Course of the Female Menstrual Cycle: A New Biomarker for the ACL Injury Risk?

Podcast: Listen to Dr. Argentieri discuss the article published in AJSM.

_____________________________________________________

Erin C. Argentieri, MS, is a translational imaging scientist and PhD candidate (graduation 2027) in the UC Berkeley–UCSF Joint Graduate Program in Bioengineering, with expertise in quantitative MRI (qMRI) techniques for neuro- and musculoskeletal imaging. Her research focuses on the development and application of advanced qMRI techniques, including T2*, ultrashort echo time (UTE), zero echo time (ZTE), and magnetization transfer (MT), as imaging biomarkers of tissue structure, composition, and physiology. To date, she has 25 publications with more than 400 citations, and an h-index of 12.

Her research career began at the University of Vermont working with Dr. Bruce Beynnon, PhD, where she investigated anatomic and biomechanical risk factors for noncontact ACL injury, recurrent ACL injury, and post-traumatic changes in joint health. This work established a longstanding research focus on understanding factors contributing to ACL injury susceptibility and its downstream consequences and resulted in multiple peer-reviewed publications.

She subsequently spent six years working with Dr. Hollis Potter, MD, as a Senior Lead Research Specialist in the Department of Radiology and Imaging at Hospital for Special Surgery, where she expanded her research into quantitative and ultrashort-echo-time MRI of musculoskeletal tissues. As PI of an HSS Radiology-in-Chief grant, she initiated a research study investigating cyclic changes in ACL T2* as a potential imaging biomarker of ACL injury risk. This work ultimately demonstrated in vivo changes in bicomponent ACL T2* across the menstrual cycle, providing evidence that ACL tissue microstructure varies with cyclic physiology. Her research has been recognized through the HSS Coleman Scholarship, UVM McClure Musculoskeletal Research Award, and poster and podium presentation awards from the Orthopaedic Research Society Meniscus Section.

Arthroscopic Posterior Bankart Repair: Risk Factors for Recurrence of Instability

Podcast: Listen to Dr. Boileau discuss the article published in AJSM.

_____________________________________________________

Pascal Boileau is Professor of Orthopaedic Surgery and Traumatology. He served as Chairman of the Orthopaedic Surgery and Traumatology Department in University Hospital of Nice until 2020 and acted as Vice-Dean for Research at the Medical University of Nice. Since November 2020, he is working at the ICR (Institut de Chirurgie Reparatrice), a private clinic, taking charge of shoulder diseases and sports-related injury in Nice.

He specializes in shoulder arthroscopy, minimally invasive surgery, and shoulder replacement for the treatment of rotator cuff tears, shoulder instability, osteoarthritis, and fractures around the shoulder. His considerable experience on surgical technique and clinical research work result in better outcomes in patients with shoulder osteoarthritis, instability and cuff tear arthropathy due to increasing interests on arthroplasty. He also deals with sports medicine for professional athletes and general populations with sports injuries of the shoulder.

Pascal Boileau performed three fellowships:

By outstanding basic and clinical research on shoulder replacement, he received many prizes and awards, including:

He participated in the design and development of many shoulder prostheses and implants, including Aequalis Anatomic prosthesis, Aequalis Reverse prosthesis, Aequalis fracture prosthesis. He also designed the first long-peg Aequalis glenoid baseplate for BIO-RSA. He is one of the conceptors of the first convertible “onlay” prosthesis (Aequalis Ascend prosthesis) and the convertible “flush lay” prosthesis (Perform prosthesis). He is one of the conceptors of the Perform Fracture Prosthesis, an anatomic and reversed prosthesis for fractures, recently released. He is also the conceptor and designer of the Aequalis IM Nail, the first and only 3rd Generation IM Humeral Nail based on tuberosity fixation (instead of Humeral head fixation) with locking screw technology. He is also the inventor of the Nice knot using a looped suture (Nice Loop).

He is the inventor of many open and arthroscopic surgical procedures or techniques including:

Another field of his interests is the development of one of the first softwares to plan shoulder arthroplasty with 2D/3D kinematic models of joints using computer-based virtual figure drawings and motion analysis. Pascal Boileau created a start-up, the IMASCAP company with Gilles Walch, MD and Jean Chaoui PhD that led to the development of the BLUEPRINT software for planning shoulder replacement. The IMASCAP company and Blueprint software were acquired in 2017 by WRIGHT Medical and then by STRYKER.

Since 2003, he successfully organized the Nice Shoulder Course, biannually from 2004 with the 13th edition coming in 2026. This course is one the most attended shoulder courses with among 1000 shoulder surgeons from more than 60 countries. He actively participates in international meetings and symposiums to share his knowledge and experience with peers and younger surgeons. From 2006 to 2010, he acted as General secretary of SECEC and, from 2010 to 2012, served as President Elect of the European Shoulder & Elbow Society (SECEC).

He is a Honorary member of the French Orthopaedic and Traumatolgy Society (SOFCOT) and French Arthroscopy Society (SFA). He is also an associated member of many scientific national and international learned societies of orthopaedics and shoulder and elbow surgery, including AAOS, ASES, SECEC-ESSE, DVSE, Polish, Korean, Portuguese Shoulder & Elbow Society.

Dr. Boileau has published more than 250 scientific articles in peer review journals until now with many being among the most cited articles. His publications concern all fields of shoulder surgery and some articles are landmark articles.
