Anterolateral dislocation of the fibular head from the tibiofibular joint was detected on the anteroposterior and lateral radiographs (Figure 1).
Post-reduction (a) anteroposterior and (b) lateral radiographs of tibiofibular dislocation (arrow). (c) Axial and (d) coronal computed tomography scans of right knee show reduced proximal tibiofibular joint (arrows).

Deformity disappeared after reduction (Figure 2).
(a) Sagittal, (b) axial, and (c) coronal T2 magnetic resonance images show bucket-handle meniscal tear accompanying proximal tibiofibular dislocation (arrows).

A bucket-handle lateral meniscal tear was also detected as an intraarticular pathology (Figure 3).
Postoperative (a) anteroposterior and (b) lateral radiographs show open reduction and screw fixation of proximal tibiofibular dislocation (arrows).

The fibular head, which was unstable in the proximal tibiofibular joint, was reduced, and fixation was performed under fluoroscopy using one cannulated screw (Figure 4).
