AAOS joins CAOS International

The American Academy of Orthopaedic Surgeons recently joined the International Society for Computer Assisted Orthopaedic Surgery (CAOS International) as an institutional member. Based in Bern, Switzerland, CAOS International brings together those individuals from around the world, who, by their contributions and activities in the areas of research, clinical study and clinical use, have an interest in computer-assisted orthopaedic surgery.

CAOS International was established in 2000 as a forum for exchanging investigative and clinical information on computer-assisted preoperative planning, intraoperative execution and postoperative follow-up. It also promotes partnerships between orthopaedic surgeons and technologists to help integrate computer-assisted surgical tools and techniques successfully into daily clinical routines.

The AAOS Biomedical Engineering Committee, chaired by John S. Kirkpatrick, MD, has been pursuing CAOS-related activities for several years. Anthony M. DiGioia III, MD, another committee member, is the U.S. regional representative to CAOS International and the director of the Institute for Computer-Assisted Orthopaedic Surgery (ICAOS) at the Western Pennsylvania Hospital. He and Branislav Jaramaz, PhD, associate and scientific director of ICAOS, have been instrumental in spurring the Biomedical Engineering Committee to delve more deeply into CAOS-related activities.

Last year, Dr. DiGioia and the Biomedical Engineering Committee successfully lobbied the American Society for Testing and Materials (ASTM) to form a new subcommittee on CAOS. This collaborative effort between physicians, technicians and scientists aims to develop standards that improve clinical outcomes for computer-assisted orthopaedic surgery patients. The ASTM CAOS subcommittee is currently drafting a technical standard on the measurement of the positional accuracy of computer-assisted orthopaedic surgical systems.

The AAOS supports the activities of CAOS International and encourages members to pursue a better understanding of and familiarity with CAOS-based technologies through Instructional Course Lectures, symposia and exhibits on CAOS.
