Case contributed by Dr Mostafa El-Feky

Presentation

Painful left knee.

Patient Data

Age: 40 years
Gender: Male
MRI

Left knee

Constant ill definition of the anterior cruciate ligament in all pulse sequences reflecting underlying tear.

An abnormal signal is noted at the peripheral most portion of posterior horn medial meniscus, suggestive of a ramp lesion.

Moderate effusion with synovitis.

Buckling of an otherwise intact posterior cruciate ligament.

Suprapatellar plica noticed, with no related cartilaginous erosions identified.

A small cyst is noted in the semimembranosus gastrocnemius bursa denoting popliteal cyst.

T1 hypo, T2 hyperintensity noted at lateral tibiofemoral compartment, reflecting marrow contusion.

Case Discussion

MRI features are reflecting anterior cruciate ligament tear with associated moderate effusion and abnormal signal noted at the peripheral most portion of posterior horn medial meniscus, consistent with a ramp lesion. Meniscal ramp lesions are often associated with anterior cruciate ligament tears 1.
