[Intra-articular punctures and injections]

Joint punctures and injections are a widely used approach to obtain a differential diagnostic assessment for the formation of a treatment concept for recurrent joint effusions, to exclude a periprosthetic infection in painful and loosened endoprostheses before a planned revision, to assign the origin of pain symptoms to a specific joint or to provide a treatment for arthritis of any kind. In all medical fields the standardization of processes has progressed. Therefore, for joint punctures there are standards relating to the implementation and hygiene of intra-articular punctures or injections in order to prevent the occurrence of complications, such as joint infections.
