Disruption of the inferior popliteomeniscal ligamentous fascicle.

The superior popliteomeniscal ligamentous fascicular injury association with lateral meniscal injury has been previously documented in the literature. Both superior and inferior popliteomeniscal ligamentous injuries have demonstrated associations with lateral meniscal motion, and these ligaments can be disrupted in posterolateral corner knee injuries as well. The current case demonstrates an unusual case of isolated inferior popliteomeniscal ligamentous fascicular injury. We examine and discuss its association with the superior popliteomeniscal ligament, posterolateral corner injuries and the fascicular relationship to lateral meniscal tears.
