Towards Precision Medicine: Tailoring Diagnosis Based on MRI Evaluation of Adult Lateral Discoid Meniscus Injury

Abstract

Background Amongst the various forms of knee joint pathology, lateral discoid meniscus injury presents unique challenge owing to rare incidence and diverse clinical presentations. The advent of MRI has significantly enhanced the ability to visualize and characterize soft tissue injuries, the translation of these imaging findings into meaningful clinical decisions remains a crucial aspect of patient care. The purpose of the study was to evaluate the efficacy of MRI in diagnosis of adult lateral discoid meniscus injury and quantify changes in associated parameters. Main Body: Results: The wedge sign was notably reduced in Group A compared to Group B, while the incidence of the fat angle sign exhibited a marked increase compared to Group B. Free edge height, body width, and free edge height/body height of meniscus showed significant elevation compared to Group B, conversely, joint capsule edge height and joint capsule edge height/body height displayed a significant decrease compared to Group B. (P<0.05). Conclusion MRI imaging proves to be efficacious in diagnosing lateral discoid meniscus injuries in adults, exhibiting notable differences in related parameters compared to individuals without injury. This underscores its value in injury diagnosis and highlights its potential clinical application.
