Abstract
The present invention relates to an insert unit inserted during an artificial knee joint operation. An insert unit for an artificial knee joint according to an embodiment of the present invention includes a tibial member configured for coupling to the end of the tibia during an artificial knee joint operation, an insert configured for coupling to an upper side of the tibial member, and a locking rod coupling together the tibial member and the insert by penetrating through the tibial member and the insert, wherein the locking rod comprises a head portion formed at the upper end, and the head portion comprises a lip protruding outward to provide a constraint in relation to the insert during an articular movement such that the locking rod does not dig into the tibial member, to increase a coupling strength of the insert unit.
