An implant part for an orthopedic knee joint prosthesis has a surface region which faces and contacts bone in an implanted state. A least part of the implant part is made from a plastics material, in particular polyether ether ketone or polyether ether ketone composite material. The implant part has a three-dimensional surface structure in the surface region facing the bone. The three-dimensional surface structure includes a rib structure, a first rib portion extending in a plane on a surface of the surface region, or a first rib of the rib structure extending in the plane on the surface of the surface region, and a second rib portion extending in the plane on the surface of the surface region, or a second rib of the rib structure extending in the plane on the surface of the surface region extending in the plane in different directions, at least in portions.
A femoral implant part for an orthopedic knee joint prosthesis, the femoral implant part comprising at least one surface region configured to face bone and be in contact with the bone in an implanted state, at least part of the femoral implant part being made from a plastics material, the femoral implant part comprising a three-dimensional surface structure in the at least one surface region, the three-dimensional surface structure comprising at least one rib structure, at least one first rib portion extending on a surface of the at least one surface region in a plane, or a first rib of the rib structure extending on the surface of the at least one surface region in the plane, and a second rib portion extending on the surface of the at least one surface region in the plane, or a second rib of the rib structure extending on the surface of the at least one surface region in the plane, extend in the plane in different directions, at least in portions.
A tibial implant part for an orthopedic knee joint prosthesis, the tibial implant part comprising at least one surface region configured to face and be in contact with bone in an implanted state, at least part of the tibial implant part being made from a plastics material, the tibial implant part comprising a three-dimensional surface structure in the surface region, the three-dimensional surface structure comprising at least one rib structure, at least one first rib portion extending on a surface of the surface region in a plane or a first rib of the rib structure extending on the surface of the surface region in the plane, and a second rib portion extending on the surface of the surface region in the plane, or a second rib of the rib structure extending on the surface of the surface region in the plane, extend in the plane in different directions, at least in portions.
