Best Practice Case Studies-Lateral Meniscus Tear

Video Transcription

Video Summary

Barry Bellosis, a musculoskeletal radiology fellow at Stanford University, discusses a 24-year-old female patient who presented with acute right knee pain, indicating a potential lateral meniscus tear. A normal meniscus appears as a low signal intensity structure on MRI, resembling a bow-tie. A tear, such as a boccet handle tear, shows abnormal signal reaching the surface and can result in contour irregularities. This specific tear type involves the longitudinal separation of the meniscus, resembling a bucket handle. It is visible on MRI as a displaced fragment and a double PCL sign, reflecting its particular characteristics.
