Abstract
A knee joint endoprosthesis set for replacing a knee joint of a patient, a patient knee joint endoprosthesis set, and a knee joint endoprosthesis system. The knee joint endoprosthesis set includes a knee joint endoprosthesis with a femoral component, a tibial component, and a first meniscal component. The knee joint endoprosthesis set also includes a second meniscal component configured differently from the first meniscal component. One of the first and second meniscal components is arranged between the femoral component and the tibial component for forming the knee joint endoprosthesis.
