Photos from the 102nd Annual Meeting

Welcome From the President

NEW James Slough

Welcome to the Clinical Orthopaedic Society website. Our society has a long history of education, networking, camaraderie, and leadership development with great small to medium-sized annual meetings allowing for an intimate learning experience. Presentations are appropriate for the general orthopaedic surgeon and run the gamut of surgical subspecialties and the 2.5 day format allows for more diverse educational experiences than specialty society meetings. The COS is a national society although sometimes considered one of the regional orthopaedic societies.

Founded in 1912, the COS has kept the importance of the physical examination as a central component in the diagnosis and management of musculoskeletal conditions. We have continued the tradition of live patient presentations with audience participation to allow for more interactive learning and sharing examination pearls. One of the tenets of the society are in the words of the COS seal, “learn by seeing, hearing, fellowship and criticism”.

The COS is excited to bring our new digital poster series to our New York City meeting allowing for more resident / fellow presentations and poster exhibits enhancing the ability to ask questions, interact with the authors, and allow more viewing opportunities.  Education and the remaining format setup changed over the years, but the importance of diagnosis and physical exam is still just as important.

While on the website, please look at our history as well as our exciting upcoming 103rd meeting in New York City this September.  We look forward to seeing you there and the majority of people who come to one of our meetings for the first time are impressed by the meeting format, value of presentations, and opportunities to interact.

The Mission of the Clinical Orthopaedic Society

Founded in 1912, the mission of the Clinical Orthopaedic Society is to optimize the science of the physical examination as the central component in the diagnosis and management of musculoskeletal conditions and to educate society on orthopaedic issues impacting patient care.

Resident Happy Hour

Resident Happy Hour Photo

The Clinical Orthopaedic Society in conjunction with Stryker Orthopaedics sponsored a Resident Happy Hour at the American Tap Room in Bethesda last April. Residents from four DC and Maryland orthopaedic residencies were invited. There was an excellent turn out from the residents and a chalk talk was given by Dr. Peroutka on the benefits of joining and being involved in professional societies. Given the excellent response by residents we hope to sponsor more events to engage residents. If you have a group of residencies in your area and are interested in arranging a resident happy hour please contact the COS at
