ABSTRACT

Diagnosis: 1. Mid-substance anterior cruciate ligament tear. 2. Lateral capsular avulsion consistent with Segond fracture. 3. Partial thickness tear of medial collateral ligament.

History: 47 y/o female status/post-skiing accident in which the patient’s right knee was clipped by a snowboarder while her leg was planted and internally rotated.

Findings: 1. A-P radiograph of the knee taken at referring facility shows a Segond fracture. 2. FSE proton density with fat saturation sagittal oblique MR image shows a mid-substance anterior cruciate ligament tear with increased obliquity of the ACL and a joint effusion. Edema of posterior tibial plateau correlative with the Segond fracture is also seen. 3. More lateral FSE proton density with fat saturation sagittal oblique MR image shows both the high-signal-intensity edema of the Segond fracture and edema of the lateral femoral condyle, injuries seen with ACL tear. 4. T1-weighted coronal MR image shows indistinctness of the medial collateral ligament at the joint line and low-signal- intensity edema of the lateral tibial plateau and defect of the Segond fracture. 5. FSE T2-weighted with fat saturation coronal MR image shows the increased signal intensity within the medial collateral ligament consistent with a partial thickness tear. The Segond fracture is seen as a lateral capsule avulsion with a focal osseous deficit at the lateral proximal tibia. Associated with this is high-signal-intensity edema/contusion of the lateral tibial plateau and lateral femoral condyle.

Ddx: Combined findings are characteristic for ACL, MCL tears and Segond fracture

Exam: Tenderness and swelling of the right knee, + Lachman/anterior drawer, + valgus stress test. No laboratory test results were available.

No MeSH data available.
