title: Periprosthetic patellar fractures.
abstract: Periprosthetic patellar fractures represent a spectrum of injuries to a patient with a total knee arthroplasty. They range in severity from an inconsequential injury, which does not compromise function, to a severely debilitating injury that may require advanced reconstructive measures. This article will outline the epidemiology and risk factors associated with periprosthetic patellar fractures. Treatment options as they relate to injury mechanism, fracture severity, patellar component stability, and remaining bone stock will also be discussed. Finally, a review of the current literature regarding the results of treatment will be presented.
