Reason: Evaluate for meniscal tear versus ligamentous injury History: Pain, buckling Due to the patient's body habitus, the high-definition coil could not be utilized resulting in suboptimal image quality.MENISCI: Patient motion artifact limits evaluation of the menisci. There is increased signal abnormality within the posterior horn and body of the medial meniscus which may reflect intrasubstance degeneration, however, this is suboptimally evaluated due to extensive patient motion artifact. There may be a small undersurface tear of the posterior horn and body of the medial meniscus but this is equivocal. The lateral meniscus appears intact, although evaluation is again suboptimal.ARTICULAR CARTILAGE AND BONE: There is bone marrow signal abnormality within the posterior aspect of the lateral tibial plateau.LIGAMENTS: There is disruption of the proximal and mid substance fibers of the ACL. The PCL appears intact. The MCL and LCL appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intactADDITIONAL
1. Severely limited examination secondary to patient body habitus and motion artifact. There is disruption of the proximal and mid substance fibers of the ACL with a bone contusion in the lateral tibial plateau.2. Small joint effusion. Other findings as described above.
