Distal Femoral Hinged Total Knee Replacement in Rorabeck Type 3 Distal Femur Periprosthetic Fractures in Elderly Patients.

Abstract

Background : A constrained hinge knee prosthesis offers a useful alternative treatment to internal fixation in selected elderly patients with periprosthetic fractures, and has a high probability of survival. Although the use of cemented hinge total knee arthroplasty to treat distal femoral fractures in elderly patients has some practical advantages over the use of techniques of fixation, concerns as to a high rate of loosening after implantation of these prostheses has raised doubts about their use in the past. Patients and methods : We evaluated the results of distal femoral hinged total knee replacement in the treatment of 6 fractures in six patients with a mean age of 78.8 years (72 to 86) from year 2014 to 2016 at our institute. Conclusion : This study shows the status of postoperative mobility, survival and advantages of replacement over fixation techniques in this age bracket.
