The periprosthetic fracture of the knee is a complication associated with high morbidity and its treatment is complex. The aim of this study was to present our results in the treatment of these fractures. A total of 29 cases of knee periprosthetic fractures were recorded. In 7 patients the femur fractures were treated with retrograde intramedullary nail, locking plates in 13, in 2 cases with prosthetic replacement and in 4 cases an orthopedic treatment was perform. At the tibia level the treatments included the replacement of the tibial component in one patient and another with a plate and orthopedic treatment. The results were good for the majority of patients, major complications were find in two cases with delayed union, a case of varus angulation and one infection. The blocking plates are currently the most accepted treatment in most of these fractures with the possibility of using any type of prosthetic implant.
