Knee pain following injury Note that the examination is suboptimal secondary to patient motion artifact on all sequences.MENISCI: There is vertically oriented linear increased signal intensity noted within the posterior horn of the lateral meniscus with extension laterally from the interface of the meniscus with the ligament of Wrisberg highly suggestive of a longitudinal tear ("Wrisberg rip"). Additionally, there is increased signal intensity along the undersurface of the peripheral fibers of the posterior horn of the medial meniscus which may represent a tear in the red zone; however this is equivocal.ARTICULAR CARTILAGE AND BONE: There are bone contusions within the lateral tibial plateau posteriorly and the lateral femoral condyle above the anterior horn of the lateral meniscus. Small contusions are also present within the medial tibial plateau posteriorly and medial femoral condyle above the body of the medial meniscus. There is edema within the proximal fibula at the tibiofibular articulation.Evaluation of the articular cartilage is limited by motion artifact however within these limits, there are no fluid-filled cartilage defects identified.LIGAMENTS: There is a full-thickness rupture of the ACL. The PCL, MCL, and lateral collateral ligament complex are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Limited examination secondary to motion artifact which demonstrates the presence of a ruptured ACL, longitudinal tear of the lateral meniscus, and possible undersurface tear of the medial meniscus as detailed above.
