The OMERACT TJR core domain set was defined as pain, function, patient satisfaction, revision, adverse events, and death and was endorsed, moving the field forward.

The scope of this TJR core domain set should be limited to THR and TKR but include all endstage arthritis refractory to medical treatment, osteoarthritis or rheumatoid arthritis.

General “adverse events” was kept as a core domain rather than specific adverse events.

Range of motion was added as a research agenda domain.

The next step of instrument selection for core domains using subscales of validated multidimensional instruments as candidate measures for the core measurement set for TJR trials was a clear mandate.
