Retrograde intramedullary nailing for distal femur fracture after total knee arthroplasty

Periprosthetic fractures over the total knee arthroplasty (TKA) are increasing in aged population. When open reduction is considered as a treatment option there is excessive soft tissue insult causing reduction of periosteal blood supply resulting in delayed union and weight bearing. Patient of the case of postosteoarthritis TKA with periprosthetic supracondylar fracture treated with retrograde intramedullary nailing. The patient after 12 months of follow-up gained a comparable range of motion with early weight bearing and union. Retrograde intramedullary nail, through compatible TKA component, is a feasible option and has numerous advantages over other conventional methods being less invasive, less time-consuming, less blood loss, preservation of fracture hematoma, and periosteal blood supply.
