title: Navigated total knee arthroplasty in a patient with severe diaphyseal deformities.
abstract: A 65-year-old patient presented with severe osteoarthritis of the knee, 47 years after a severe polytrauma in which he had presented diaphyseal fractures of the left femur and tibia. These fractures had been treated conservatively and had healed with major deformities. He underwent total knee arthroplasty with navigation assistance. This allowed for optimal component positioning and restoration of a correct limb alignment. The early functional result was excellent. Navigation assistance appears of particular interest for total knee arthroplasty in such cases with complex post-traumatic diaphyseal deformities.
