The National Joint Registry for England, Wales and Northern Ireland
(NJR) has extended its scope to report on hospital, surgeon and
implant performance. Data linkage of the NJR to the London Implant
Retrieval Centre (LIRC) has previously evaluated data quality for
hip primary procedures, but did not assess revision records. We analysed metal-on-metal hip revision procedures performed
between 2003 and 2013. A total of 69 929 revision procedures from
the NJR and 929 revised pairs of components from the LIRC were included.Aims
