Abstract
Disclosed herein is a temporary knee spacer system for the temporary replacement of a knee joint, which is designed for the interim phase of two-stage septic revisions of knee joint total endoprostheses. The knee spacer system can be used in particular with two-phase septic revisions with which two or more microbial germs are the cause of an infection of the knee joint total endoprosthesis and the surrounding tissue.
Claims29
A knee spacer system for the temporary replacement of a knee joint, the knee spacer system comprising:
- a tibia component, wherein the tibia component has a tibia prosthetic body, wherein the tibia prosthetic body has two running surfaces on a proximal side of the tibia component and at least one mounting surface for mounting the tibia component on a tibia on a distal side of the tibia prosthetic body;
- a first tubular and fluid-permeable connecting means for feeding a medical irrigation fluid into the tibia prosthetic body;
- a second tubular and fluid-permeable connecting means for draining a medical irrigation fluid from the tibia prosthetic body;
- an irrigation fluid inlet opening in a surface of the tibia prosthetic body, wherein the first connecting means is connected or connectable in a fluid-permeable manner to the irrigation fluid inlet opening;
- an irrigation fluid outlet opening in the surface of the tibia prosthetic body, wherein the second connecting means is connected or connectable in a fluid-permeable manner to the irrigation fluid outlet opening;
- at least one irrigation fluid exit opening in the surface of the tibia prosthetic body, which is connected in the interior of the tibia prosthetic body with the irrigation fluid inlet opening in a fluid-permeable manner;
- and
- at least one irrigation fluid entry opening in the surface of the tibia prosthetic body, which is connected in the interior of the tibia prosthetic body with the irrigation fluid outlet opening in a fluid-permeable manner,
- wherein the at least one irrigation fluid exit opening and the at least one irrigation fluid entry opening are arranged outside the at least one mounting surface, and
- wherein the at least one irrigation fluid exit opening in the interior of the prosthetic body is not connected in a fluid-permeable manner with the irrigation fluid outlet opening and the at least one irrigation fluid entry opening in the interior of the prosthetic body is not connected with the irrigation fluid inlet opening in a fluid-permeable manner.
