Anterior dislocation of a total knee arthroplasty in a patient with postoperative delirium: a case report

Abstract

Abstract We report a rare case of traumatic anterior dislocation in a patient with postoperative delirium following total knee arthroplasty. The patient was successfully treated by open reduction of the dislocation and polyethylene liner change. Recognition of risk factors for postoperative delirium is important for the prevention of this uncommon injury.
