The University of Pennsylvania Orthopaedic Journal (UPOJ) is an annual peer-reviewed orthopaedic journal organized and distributed by the residents of the Department of Orthopaedic Surgery at the University of Pennsylvania. Our mission is to reflect upon the preceding academic year by publishing high-quality original research from around the country as well as review articles discussing current controversial topics in orthopaedic surgery. We are proud to announce that the Journal recently had its 22nd year of publication, with a circulation volume of approximately 3,000.
