53-year-old female with history of knee pain after fall. MENISCI: There is linear signal abnormality within the posterior horn of the medial meniscus extending to the tibial articular surface compatible with a tear. The posterior root junction of medial meniscus is indistinct and possibly torn.Additionally, there is increased globular signal throughout the remaining posterior horn compatible with degeneration. There is degenerative globular signal abnormality and degenerative tearing of the lateral meniscus. There is also a femoral sided tear near the meniscal junction of the meniscofemoral ligament.ARTICULAR CARTILAGE AND BONE: There is a small cortical depression of approximately 2mm along the posterior aspect of the medial tibial plateau. There is thinning of the articular cartilage within the medial compartment as well as tricompartmental osteophytes. Increased signal abnormality within the posterior tibial plateau and lateral femoral condyle compatible with contusions. There is additional edema type signal within the anterior aspect of the medial tibial plateau possibly from direct injury.LIGAMENTS: There is complete disruption of the anterior cruciate ligament. There is increased signal abnormality within the PCL, but we see no discrete tear. The MCL and LCL are intact.EXTENSOR MECHANISM: The extensor mechanism is unremarkable.ADDITIONAL
1.Complete ACL disruption.2.Small 2mm depression fracture along the posterior aspect of the medial tibial plateau.3.Full thickness tear of the posterior horn of the medial meniscus in the background of degenerative signal abnormality. Additional tearing and degeneration is present within the lateral meniscus.4.Moderate joint effusion, degenerative changes and other findings as above.
