Periprosthetic Fracture Between a Constrained Total Knee Arthroplasty and a Long-Stem Total Hip Arthroplasty: Treatment with a Novel Device

Supracondylar fracture of the femur occurred in a patient with a well-fixed constrained condylar total knee arthroplasty and an 8-in total hip femoral revision component. This unusual fracture was treated with a novel interpositional femoral intramedullary device that connected the total knee to total hip arthroplasty. The result was good at 5 years, with healed fracture and no loosening or osteolysis of either component.
