14-year-old male with history of ACL tear, unable to bend knee in brace MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage is normal. Increased T2 signal is noted involving the apophysis at the tibial tuberosity without overlying soft tissue swelling.LIGAMENTS: Increased T2 signal along distal fibers of the ACL at its insertion indicates a sprain or partial thickness tear. No full thickness tear is present. The PCL is intact. The medial and lateral collateral ligaments are normal.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. Signal abnormality involving the distal fibers of the ACL compatible with a sprain or partial thickness tear. No full thickness disruption.2. Edema at the tibial tuberosity apophysis suggests mild apophysitis.
