Vol 17 No 5 - may 2009The Journal of the American Academy of Orthopaedic Surgeons was established in the fall of 1993 by the Academy in response to its membership’s demand for a clinical review journal. Two issues were published the first year, followed by six issues yearly from 1994 through 2004. In September 2005, JAAOS began publishing monthly issues.Each issue includes richly illustrated peer-reviewed articles focused on clinical diagnosis and management. Special features in each issue provide commentary on developments in pharmacotherapeutics, materials and techniques, and computer applications.The Journal's mission is dissemination of knowledge to improve the care of patients with musculoskeletal disorders. The Editorial Board selects articles that critically evaluate and synthesize current information on the diagnosis and management of musculoskeletal conditions and document the current state of orthopaedic practice. Because JAAOS is a review journal, certain types of material (eg, original research, case studies, animal studies, or duplicative material) are not appropriate for publication.JAAOS is published by the American Academy of Orthopaedic Surgeons, the world’s largest medical association of musculoskeletal specialists. JAAOS is provided to all members of the Academy as a benefit of membership. The Journal is also provided to residents in specified orthopaedic and osteopathic programs.
