Non-Union of Isolated Medial Condyle of Femur Hoffa Fracture: Case Report

Isolated non-united Hoffa fracture of the femur is a rare finding. They are often missed due to the nature of the fracture and when not assessed appropriately. This is a case report of a 40-year-old male who encountered a high-velocity trauma; the fracture was probably missed on plain radiographs following the trauma. The patient presented to us eight months following the trauma with complaints of pain and decreased range of motion of his right knee (10 to 80 degrees of flexion) and the patient was unable to bear weight on the affected limb. On evaluation, the patient was found to have a non-united Hoffa fracture involving the medial condyle. The patient was treated with freshening of fracture followed by rigid fixation with cancellous screws and reconstruction plate. Postoperatively by week six, the patient achieved full range of motion and was able to walk without assistance with evidence of union on plain radiographs.
