Fixation of Periprosthetic Supracondylar Femur Fractures Above Total Knee Arthroplasty – The Indirect Reduction Technique with the Condylar Blade Plate and the Minimally Invasive Technique with the LISS

“…2, Ayers, 1997;). Many factors must be considered in choosing the most appropriate management method for these fractures including the patients general health, prefracture ambulatory status, fracture pattern, location, displacement, and type of implant (Su et al, 2004). Periprosthetic fractures above total knee arthroplasties have particular risks for failure, including wide metaphyseal and diaphyseal spaces, osteoporosis, small distal femoral fragments, and prosthetic anchorage pegs reducing the sites for fixation (Kolb et al, 2010).…”

“…The Classification system of supracondylar femoral fractures above total knee arthroplasties created by (Rorabeck & Young, 1999) www.intechopen.com into account both the status of the prosthesis (that is, whether it is intact or failing) and the displacement of the fracture (Dennis, 2001). (Su et al, 2004) developed their classification system because patients are increasingly being treated operatively and the bone stock of the distal segment continues to be considered a key limiting factor to obtaining adequate fixation (Herrera et al, 2008). Their classification system takes into account the height of the fractures ( Table 2.…”

“…The number of these cases may rise quickly, given the projection that, by the year 2030, the implantation of total knee arthroplasties will increase to 3.48 million in the United States, an increase of 673% compared with 2005. The most frequent mechanism of injury is a low-velocity fall onto the knee in combination with torsion or axial compression, with a smaller proportion resulting from high-energy trauma (e.g., motor vehicle accidents) (Su et al, 2004) The complication rate of these fractures is between 25% and 75%. Conservative treatment of displaced fractures with casting results in malalignment (25-100%), non-union (20-35%), loss of motion of the knee, and inability to maintain reduction of the fracture .…”
