Endoprosthetics: Active role of the patient required

An important reason for the success of endoprosthetics is the frequency of interventions performed at the respective hospital. Further influences on the durability of a prosthesis are the materials used and the patients themselves. These are the conclusions of the 2019 annual report of the Endoprostheses Register Germany (EPRD) of the German Society for Orthopaedics and Orthopaedic Surgery (DGOOC), in which 1.3 million endoprosthetic hip and knee operations are documented. According to this, around 235,000 artificial hip joints and 178,000 knee joints were implanted in Germany in 2018. At the same time, the length of time patients stayed in the clinic after an implantation has been significantly reduced.
Accompanying diseases, medication as well as the physical and mental condition have a significant influence on the implantation result. Wound healing disorders, infections and loosening of the implant occur at least twice as frequently in smokers. Conversely, a smoking cessation 6 weeks before and 6 weeks after the procedure would reduce the smoking-related risk by 50%. Many smokers are not aware that the carbon monoxide (CO) and hydrogen cyanide contained in smoke reduces the oxygen supply to all tissues.
This also impairs the healing of wounds and bones during an implantation. Diabetes, severe overweight, dental diseases, chronic wounds or skin infections can also significantly increase the risk of complications.
