Five articles from the October 2014 issue summarized in five minutes, with the addition of a brief editorial commentary. The 5-in-5 feature is designed to give readers an overview of articles that may pique their interest and encourage more detailed reading. It may also be used by busy readers who would prefer a brief audio summary in order to select the articles they want to read in full. The featured articles for this month are “Posterior Cruciate Ligament Graft Fixation Angles, Part 1: Biomechanical Evaluation for Anatomic Single-Bundle Reconstruction," “Posterior Cruciate Ligament Graft Fixation Angles, Part 2: Biomechanical Evaluation for Anatomic Double-Bundle Reconstruction,” "Comparison of Allograft Versus Autograft Anterior Cruciate Ligament Reconstruction Graft Survival in an Active Adolescent Cohort," "Radiographic Landmarks for Locating the Femoral Origin and Tibial Insertion of the Knee Anterolateral Ligament," and "Platelet-Rich Plasma Injections for the Treatment of Hamstring Injuries: A Randomized Controlled Trial."

Most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome; however, graft choice for revision may be limited due to previously used grafts. Improved sports function and patient-reported outcome measures are obtained when an autograft is used. Additionally, use of an autograft shows a decreased risk in graft rerupture at 2-year follow-up. No differences were noted in rerupture or patient-reported outcomes between soft tissue and bone–patellar tendon–bone grafts. Surgeon education regarding the findings of this study has the potential to improve the results of revision ACL reconstruction.
