Research with data from the Swedish Arthroplasty Register

The research with data from the Swedish Hip and Knee Arthroplasty Registers has been extensive. The data in these registers is now managed by the Swedish Arthroplasty Register and the research continues. For decades, research has yielded results that have benefited patients. It has been possible to show which methods and which implants works best for which patients.

High data quality

The Swedish Arthroplasty Register data has high quality. Almost all primary knee and hip replacements performed in Sweden are included. The proportion of reoperations captured are lower than for primaries, but high enough to be useful. The register includes information about the patients, surgical methods and implants collected for several decades. The personal identification number system and access to other Swedish registers with healthcare data enable linkage. All this together makes the Arthroplasty Register an excellent source of information for research. The production of research has been considerable and hopefully continues to be so. A list of theses that wholly or partly are based on data from the Swedish Arthroplasty Register and its predecessors can be found under the heading “Theses”.

International collaboration

The knee and hip registers have had an intensive international research collaboration and this continues through the Swedish Arthroplasty Register. Representatives of the registers have been initiators of both the NARA, the Nordic Arthroplasty Register Association, and the ISAR, the International Society of Arthroplasty Registries. The Arthroplasty Register is part of many ongoing research projects with participants from several other registers around the world.
