[Arthroplasty for distal femur fracture in elderly adults. Case report and literature review].

In the treatment of distal femur fractures in osteoporotic elderly people with complex fracture patterns and articular compromise, results of internal fixation are not always satisfactory because they frequently require delaying weight bearing for long periods of time thus delaying the rehabilitation process. We report the case of a 70 year-old patient with supra- and intercondylar femur fracture treated with unconventional total knee prosthesis. We review the factors that decrease the success of internal fixation and the results that turn total knee arthroplasty into an appealing treatment for these patients, as they do not need long-term rest, they start rehabilitation early on and quickly return to the activity level they had prior to the injury.
