Periprosthetic fractures of the distal femur after total knee arthroplasty : Plate versus nail fixation.

UNLABELLED

The incidence of periprosthetic fractures about a TKA is increasing. Traditionally, these fractures are classified by their location and prosthesis integrity. In the setting of a supracondyar fracture about a well-fixed prosthesis, both plate and nail fixation of the fracture present themselves as options, each with unique benefits and pitfalls. Through review and discussion of the literature, we aim to describe some of the patient, fracture, and implant related factors that should be considered when planning fixation of periprosthetic fractures about a TKA. Additionally, we present several technical pearls that may be useful in the successful treatment of these difficult injuries.
