The Canadian Joint Replacement Registry (CJRR) was launched in May 2001 as a voluntary registry and has now been mandated in several provinces. CJRR collects patient-specific information (clinical, surgical and prosthesis) on hip and knee replacement surgeries performed in Canada.
This metadata page primarily covers CJRR data collected via CJRR systems: the legacy CJRR electronic file system, the CJRR web tool (retired in 2018) and the CJRR paper forms (retired in 2013). As of 2018–2019, CJRR data can be submitted via the Discharge Abstract Database (DAD) under Group 20. Refer to the DAD metadata page for details about the DAD.

Data on joint replacement procedures is received directly from
- Health regions
- Provincial ministries of health
Currently, CJRR reporting is mandatory in Nova Scotia, Ontario, Manitoba and British Columbia. Participation is voluntary in the other provinces and territories.
Beginning in 2018–2019, CJRR data will be sourced from the CJRR electronic file system and from the DAD Group 20 information. Data source differs by jurisdiction.
As data sources for CJRR differ by jurisdiction as of 2018–2019, email email@example.com for the latest information.
CJRR data is based on surgery date and collected by fiscal year (April 1 to March 31).
- Most recent year: fiscal year 2018-2019
- Next release: fiscal year 2018–2019 (August 2019)
- Historical series: fiscal years 2001–2002 to 2017-2018
Data from 2003–2004 onward is available for custom data requests. Please complete a data request form.
No official classification standards are used in the capture of CJRR data (outside of the DAD). Diagnosis and reason for revision are captured using drop-down categories identified by the CJRR Advisory Committee, with consideration given to the categories used by international orthopedic registries.
CJRR data elements collect patient information, surgical information and prosthesis (implant) information. As of April 1, 2012, the data elements were streamlined to a new minimum data set (MDS). These are aligned with the standard set by the International Society of Arthroplasty Registers.
CIHI ensures that the quality of the information in our data holdings is suited to its intended uses and that data users are provided with accurate information about data quality. Read more about our Data and Information Quality Program.
