You are correct. The fibular nerve (new anatomical name for it) would be the structure that you would be most concerned about.
Here is a pretty good article that relates well with this case study. "Instability of the Proximal tibiofibular joint". Sekiya JK, Kuhn JE. Journal of the American Academy of Orthopaedic Surgeons. Vol 11, No 2, March/April 2003.
they quote, "Plain film radiographs should be taken of the knee in true anteroposterior and lateral views. Comparison radiographs of the contralateral knee can substantially improve the ability to diagnose instability of the proximal tibiofibular joint. On the lateral view, the fibular head overlies the posterior border of the tibia. Resnick et al described a line on lateral radiographs that follows the lateral tibial spine distally along the posterior aspect of the tibia and defines most posteromedial portion of the lateral tibial condyle. In a normal knee, this line is found over the midpoint of the fibular head. In anterolateral dislocations, the fibular head will be anterior to this line on the lateral view. In posteromedial dislocations, all or most of the fibular head is posterior to this line on the lateral view." See below.
