The lifetime of every artificial joint is generally limited. In addition to mechanical factors, infection is the biggest enemy of the endoprosthesis. It may become loose in its anchoring, and pain and limited mobility may develop. Surgery to replace the endoprosthesis with a new joint is then usually necessary.
Thanks to advances in medicine, the use of preventive measures, modern materials and surgical techniques, it has been possible to continually reduce the risk of infection-related loosening of the endoprosthesis. This means that the artificial joint can remain in the body for longer and longer. The use of antibiotic-loaded bone cement reduces the risk of what is known as periprosthetic joint infection.
Studies show that endoprostheses anchored using bone cement have a particularly long lifespan. This means that any revision surgery (that is, replacement of the endoprosthesis) that may become necessary can be avoided, or at least deferred for a long time.
