Abstract
Supracondylar fracture of the femur is one of the severe complications after TKA. It is usually treated by plate and screws, intramedullary rods, revision TKA or external fixator, but its results are not adequate for bone union, range of motion and other functions. Recently it is treated by the retrograded intramedullary supracondylar nail and the result is reported as excellent. We operated on two cases of this fracture (one is PS type component and the other is CR type) of this using nail by minimum incision and invasion through the patellar tendon. We carefully reamed the entrance point and forced it into the bone marrow manually without drilling. After rehabilitation, they regained good functions close to the preinjury conditions. We therefore think that this is a useful and safer surgical method for this type of fracture for both PS and CR TKA components.
