Provided is an artificial knee joint with which it is possible to restore the anterior cruciate ligament to a state of functionality close to the original, using an artificial knee joint. This artificial knee joint (1) is designed for use in total knee replacement surgery, wherein: the artificial knee joint (1) is provided with a femur member (10) and a tibia member (20); and a ligament passage hole (20h) that passes through the tibia member (20) is formed in the tibia member (20), at the location where the anterior cruciate ligament (ACL) was present in the knee prior to replacement with the artificial knee joint (1). This makes it possible, by passing the ligament through the ligament passage hole (20h), to position the ligament so as to link the distal tip (DT) of the femur (F) and the proximal end (PE) of the tibia (T), whereby it is possible to restore the anterior cruciate ligament (ACL) to a state substantially identical to that of the knee prior to replacement with the artificial knee joint (1). |
