Best Practice Case Studies-Anterior Cruciate Ligament Tear

Video Transcription

Video Summary

In this video, Sagar Wagle, a musculoskeletal radiology fellow at Stanford University, reviews an MRI of a 25-year-old male suspected of an ACL tear following a volleyball injury. He demonstrates the normal appearance of an ACL on MRI, highlighting its oblique orientation, tautness, and low signal intensity. In contrast, a high-grade ACL tear exhibits thickened fibers with increased signal intensity and is often accompanied by knee joint effusion and lipohemothrosis. The patient’s MRI confirms a complete ACL tear, characterized by truncated, sagging fibers and significant joint effusion.
