Patient Data
Age: 18 years
Gender: Male
From the case:
Posterior oblique ligament injury
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/106231/annotated_viewer_json?iframe=true\u0026lang=us"}
- Subtle marrow edema predominantly posterior to the femoral MCL insertion, more in line with the POL attachment.
- Small amount of fluid around the ligaments in this region, also enveloping the distal adductor tendons, and the adductor tubercle.
- Subtle chondral irregularity of the lateral tibial plateau.
- Mild knee joint effusion.
From the case:
Posterior oblique ligament injury
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/106232/annotated_viewer_json?iframe=true\u0026lang=us"}
Arrows: bone marrow edema adjacent to the POL/MCL attachment.
Arrowheads: fluid tracking along the ligament.
Case Discussion
Subtle posteromedial corner injury, with the bone edema and fluid more in line with a low grade POL than MCL tear.
