The incidence of total knee arthroplasty (TKA) is increasing, as are periprosthetic supracondylar femoral fractures. Treatment is complex and may involve the use of a retrograde intramedullary femoral nail, and it is essential to know the nail will fit through the femoral prosthesis in line with the intramedullary canal. ⋯ A comprehensive data set lists manufacturer, model, size, minimal intercondylar notch distance and position. This will be of practical use when planning the operative management of periprosthetic supracondylar femoral fractures.
