Simultaneous ipsilateral knee dislocation and hip fracture: A case report

Hip fracture is one of the main causes of medical attendance in trauma centers. By contrast, knee dislocation is a challenging and limb-threatening injury. We report a case of a 68-year-old male who sustained a simultaneous ipsilateral hip fracture and knee dislocation after a low-energy fall. Popliteal artery and common peroneal nerve injuries were associated. Knee dislocation treatment included closed reduction, external fixation and popliteal artery repair. Hip hemiarthroplasty was performed using a direct anterior approach. Revision multiligament knee reconstruction surgery was not considered. A rehabilitation program achieved a good long-term functional outcome. Simultaneous ipsilateral knee dislocation and associated proximal femoral injuries are rare and challenging, potentially requiring long-term staged management. The direct anterior approach to the hip is worth consideration when additional lower limb injuries are present, especially in the setting of a knee spanning external fixator.
