ANCHOR History

Mission Statement:

ANCHOR is a multicenter clinical research group investigating adolescent and adult hip disorders. We are focused on improving patient care through research, education and mentorship.

Purpose and Long-Term ANCHOR Goal

To collect data from patients undergoing hip surgery in order to analyze the effects of surgical treatment on patients with hip problems. Over time, we hope to better identify and characterize the most important determinants for treatment outcomes while improving the diagnosis, surgical care, and quality of life of patients with pre-arthritic hip disease (femoroacetabular impingement and dysplasia).

Today, numerous medical centers and surgeons are part of this group of highly-dedicated surgeon researchers who hope to, over time; identify the most important determinants of treatments outcomes.

History of ANCHOR: From Concept to Creation




In 2006, during AO Hip Preservation Course, several leading orthopaedic surgeons began foundational discussions regarding the need to organize a hip preservation research group. Study group discussion was organized by Dr. Michael Millis, a founding member of the ANCHOR team.

In 2007, a meeting took place in Saint Louis, Missouri to officially organize a core group of orthopaedic surgeons interested in advancing their research efforts through multi-center collaboration and investigation. During this year, multi-center data forms, data collection protocols/guides and an electronic database were developed in collaboration with Dr. J. Phillip Miller, Director of the Biostatistics Core at Washington University in St. Louis. Monthly surgeon conference calls were scheduled and retrospective, collaborative studies were conducted throughout the year.

In 2008, the Academic Network of Conservational Hip Outcomes Research “ANCHOR” study group was formed, prospective periacetabular osteotomy (PAO) data collection began, three new sites were added to the group (Detroit-Beaumont, Texas Scottish-Rite Hospital and University of Colorado) and additional grant funding was provided by the NFL and Washington University’s Institute of Clinical and Translational Sciences.

In 2009, prospective data collection on femoroacetabular impingement (FAI) surgery began to be collected, X-ray and disease classification was studied and additional funding was provided by Barnes Jewish Hospital (BJH) in St. Louis, Missouri.
