ABSTRACT

Diagnosis: Isolated Posterior Cruciate Ligament Tear

History: Patient is status post motor vehicle injury. He complains of difficulty walking and knee pain.

Findings: MR images of the left knee demonstrate a large joint effusion. Heterogeneous high signal is seen within the posterior cruciate ligament, consistent with a complete tear. There is a significant degree of bone marrow edema within the anterior lateral tibial plateau, and an occult tibial plateau fracture cannot be completely excluded. Additionally, there is abnormal vertical high signal within the medical meniscus, consistent with a free edge traumatic tear. The lateral meniscus is normal. The medial and lateral collateral ligament complexes are normal. The anterior cruciate ligament is also normal.

Ddx: A mid-substance interstitial lesion (most common). Complete disruption at the genu Avulsion at the tibial attachment (least common). - this requires reduction of osseus fragments to increase the chance of healing.

Dxhow: Surgically.

Exam: The physical examination noted a joint effusion.

No MeSH data available.
