Periprosthetic fractures have an incidence of 0.3-2.5% after a primary total knee arthroplasty (TKA) and 1.6-38% following revision TKA. Because the number of TKAs is expected to increase by 673% by 2030, the incidence of this complication is expected to rise as well. Osteoporosis is the single most important contributor to periprosthetic fractures around the knee. The most common mechanism of injury is a fall onto the knee, but other causes include motor vehicle accidents, seizures, and forced manipulation for a stiff knee. The main goal of treatment should be fracture healing, pain-free function, and early functional mobility.
