A Review of Magnetic Resonance Imaging Findings in Knee Cruciate Ligament and Meniscus Injuries

This study comprehensively reviews magnetic resonance imaging findings of cruciate ligament and meniscus injuries in the knee and summarizes their clinical and rehabilitative implications. MRI enables precise visualization of soft tissue, ligament, and cartilage pathology without radiation exposure, making it essential in musculoskeletal evaluation. Characteristic MRI findings of anterior cruciate ligament, posterior cruciate ligament, and meniscal injuries are described according to imaging sequences. ACL and PCL tears can be distinguished by signal intensity changes and fiber discontinuity, while postoperative graft remodeling and different meniscal tear patterns including horizontal, longitudinal, and radial types are also summarized. These findings highlight the role of MRI not only in diagnosis but also in postoperative assessment and rehabilitation planning. This review is expected to improve diagnostic accuracy and support evidence-based rehabilitation. Future studies should verify the diagnostic reliability of MRI sequences and examine their association with functional recovery.
