Periprosthetic Femoral Supracondylar Fracture After Total Knee Arthroplasty With Navigation System

We report 1 patient with a supracondylar periprosthetic fracture 1 month after computer-assisted total knee arthroplasty. The fracture line extended from previous anchoring pinholes into the supracondyle area. Intramedullary nailing of the left femur was performed under close reduction. The possible complication of pinhole fracture to total knee arthroplasty with navigation system should be kept in mind.
