Recently, as the elderly population increases, the incidence of total knee arthroplasty has increased, with a concomitant increase in the frequency of periprosthetic fractures. To determine the treatment plan for fractures, the treatment method should be determined by the patient's age, osteoporosis, fixation status of the implant, and type of fracture. In recent years, operative treatment with reduction and stable fixation, rather than non-operative treatment, was used to promote early joint movement and gait. On the other hand, it is necessary to select an appropriate operative method to reduce complications of surgery, such as nonunion and infection, and expect a good prognosis. In this review, periprosthetic fractures were divided into femur, tibia, and patella fractures, and their causes, risk factors, classification, and treatment are discussed.

Periprosthetic fracture with a comminuted fracture in the medial cortex of the distal femur was fixed with dual locking plates using the minimally invasive plate osteosynthesis (MIPO) technique.
