Osteosynthesis after periprosthetic fractures of the knee joint

Abstract

Periprosthetic fractures around the knee joint are of increasing relevance due to increasing numbers of total knee replacements and increasing life expectations. These fractures can be a real challenge due to an often limited patient compliance, reduced bone quality and impaired bone perfusion of potential intramedullary shafts resulting in poor healing and lack of fixation options for screws. These fractures necessitate special knowledge and approaches, which are systematically dealt with in this article, beginning with the correct diagnostics through to the most recent developments in the field of osteosynthetic techniques. The trends of minimally invasive techniques are presented and the options and limitations are described.
