摘要：
A tibia component of a knee arthroplasty to be connected to a tibia includes a first tibia connecting structure and a second tibia connecting structure. The first tibia connecting structure can be inserted into a radial groove on the tibia along a radial direction of the tibia to limit the motion of the tibia component in the axial direction of the tibia. The second tibia connecting structure can be inserted into an axial groove on the tibia along the axial direction of the tibia to limit the motion of the tibia component in the radial direction of the tibia. The first and the second connecting structures provide the radial and axial bonding force to the tibia and the knee arthroplasty, so that the amount of bone cement used can be reduced and may beneficial to revision knee arthroplasty operation.
