Isolated Dislocation of Proximal Tibiofibular Joint: A Case Report

OBJECTIVES: Proximal tibiofibular joint luxation is very rare condition and usually missed in the ED. The aim of the study is if a patient is brought to ED with knee injury, we should keep in mind this pathology. METHODS: A 23 year old man was admitted to emergency department with knee pain and restricted movement of the knee during the football match. Physical examination revealed mild swelling and limited ROM on his knee. We took AP and lateral X-rays immediately. We diagnosed the proximal tibiofibular luxation with X-rays. After diagnosing this injury we reducted this joint luxation with closed reduction immediately. Knee joint was immobilized with casting. Magnetic resonance imaging was applied. Casting was removed three weeks later after the diagnosis. Passive range of motion exercises were applied. RESULTS: In the second month examination, there is no pain in his knee joint and the range of motion was full. There was no neoruvascular pathology in the physical examination of the knee. In the MRI findings proximal tibiofibular ligament had mild eudema, there was a contusion area in the lateral plateau and the other knee ligaments was normal. CONCLUSION: Proximal tibiofibular joint injury is very uncommon pathology, If the pathology is diagnosed on time , it can be treated appropriately to prevent unnecessary complication. The main problem of this injury is correct and timely diagnosis
