Newsletters

We would like to update you regarding the ongoing activities of ARCO during the past year and inform you of what will be happening going forward. We are excited to say that the COVID pandemic actually stimulated us to work together in ways that we have not utilized previously. We have been able to use ZOOM meetings to engage our members internationally. We have worked on several projects with different individuals taking the lead role to guide the process. We believe that this provides us with a strategic map for increasing our collaborations and our impact on the medical community.

BIENNIAL MEETING

Our last International Meeting was held in the beautiful seaside city of Dalian, China. Hosted by Dewei Zhao, MD, PhD, the meeting provided a comprehensive overview of our current understanding of the natural history and treatment of osteonecrosis as was an opportunity to see what is currently being studied throughout the world. We had hoped to follow this with a meeting in Seoul, Republic of Korea in May 2021. However, the COVID pandemic prevented us from moving forward. Our team in Korea – including Doctors Shin-Yoon Kim, Yong-Chan Ha, and Kyung-Hoi Koo – have begun planning for a meeting to be held in September of 2022 in Seoul, Korea. Stay tuned for more information as the plans become finalized. We look forward to another outstanding meeting!

ARCO Website

The new website is now up and running! Our Society’s website has been a work in progress over the past year. We contracted with a website design and hosting firm to provide us with a new site infrastructure based on WordPress Content Management System which will allow us to update information on the website more easily and without going through a web designer for each update. We will continue to update the website with news of our impending meeting in Korea, new ARCO-sponsored journal articles as they are published, and other news from the Board to our members.

Projects and Publications

While COVID may have prevented us from meeting together in one location, it certainly did not dampen our enthusiasm to work together. This effort has resulted in seven journal publications since January of

2020 – quite an accomplishment! These articles involved Delphi Surveys, Task Forces, and other Collaborative Groups within our membership to address etiologic classification criteria for glucocorticoid- and alcohol- associated osteonecrosis, develop the 2019 ARCO Staging System for Osteonecrosis of the Femoral Head, and set the framework for developing evidence-based clinical practice guidelines. Another manuscript about to be submitted for publication addresses a new classification system regarding size of the osteonecrotic lesion using CT imaging. The following is a listing of the current publications.
