The cover article of the October 15th issue of AFP reviews the diagnosis, management, and prevention of anterior cruciate ligament (ACL) injuries. Although we have always recognized the importance of including high-quality illustrations of relevant anatomy and physical examination maneuvers in articles like these, this article also includes short videos of diagnostic and prognostic tests that you can watch on the AFP web page or on the AFPJournal YouTube channel. Click on the image below to see a demonstration of the Lachman test, which the authors note is the most accurate test for detecting an ACL injury. Eventually, we hope to build a library of online videos of common examination skills and procedures in family medicine. In the meantime, don't miss the AFP By Topic collection on Musculoskeletal Care, which contains links to online content on joint injections, fracture management, and approaches to musculoskeletal problems organized by region of the body.
