Primary total knee arthroplasty for complex distal femur fractures in elderly patients.

Fractures of the distal femur in the geriatric population are associated with a high incidence of postoperative complications and poor results. Nonunion, loss of fixation, and malunion of these fractures occur with all types of treatment. The postoperative treatment of these patients demands a lengthy period of limited weightbearing that can increase the rate of medical complications.

Educational presentation has been transformed by the use of computers and digital projectors.
