Proximal tibiofibular joint dislocation treated using flexible and permanent syndesmosis fixation

Abstract

We present the case of a 40-year-old man who suffered an isolated proximal tibiofibular dislocation of the left knee after a trauma during a soccer game. Physical examination and radiographic imaging revealed an anterolateral dislocation of the proximal fibula. The diagnosis was confirmed by MRI. The treatment choice was open reduction and internal fixation under direct visualisation using flexible and permanent internal fixation. Postoperative treatment includes knee immobilisation during the first week, and partial weight was allowed for 2 weeks progressing to full weight bearing over 4 weeks. The patient started a gradual and progressive physical therapy programme with range of motion exercises, muscle strengthening and gait training. Full knee range of motion was achieved after 4 weeks. No complaint of pain or hardware discomfort was reported, and the patient is back to daily life and sports activities after 6 months of surgical treatment.
