An anatomic study of the popliteofibular ligament.

Our study was prompted by the varied reports in literature about the existence of the popliteofibular ligament as an integral part of the posterolateral corner of the knee. We performed 25 formalinised cadaveric knee dissections and identified the popliteofibular ligament. It was on an average 11.06 (5-16) mm in width and 11.8 (6-16) mm in length. Our study did not include a functional evaluation. We found the ligament to be a constant structure of the posterolateral knee complex, and recommend its repair in acute injuries as well as reconstruction in chronic injuries of the posterolateral corner of the knee.
