Just a “Co-incidence?” Magnetic Resonance Imaging Analysis of Kaplan Fiber Injury in the Setting of Acute Anterior Cruciate Ligament Tear
Conference Year
January 2019
Abstract
Purpose: The aim of this study is to determine the incidence of Kaplan fiber injury on magnetic resonance imaging (MRI) in patients diagnosed with acute anterior cruciate ligament (ACL) tears. Methods: The picture archiving and communication system at a single academic hospital was queried for ACL tears over the period of January 2015 to November 2018. During this time, 495 MRIs were identified as having ACL tears, and 102 were included in the final review. A fellowship-trained musculoskeletal (MSK) radiologist confirmed the ACL tears and noted the Kaplan fibers to be either torn, intact, or not visualized on axial, sagittal, and coronal images. Results: The MSK radiologist found Kaplan fiber injury on MRI in 56% of the cases. Conclusions: This study shows that a moderate share of patients with a known ACL tear on MRI have a concomitant Kaplan fiber injury. Level of Evidence: Level IV, case series study.
