Hip and knee replacements are surgeries aimed at improving the functioning and quality of life of almost 113,000 Canadians annually. Hip and knee replacement is 1 of 5 priority areas targeted for shorter wait times in Canada. The number of hip replacements in Canada increased 20% between 2009–2010 and 2014–2015. The number of knee replacements increased by 20.3% over the same period.

CIHI developed the Canadian Joint Replacement Registry (CJRR) in 2001 in collaboration with the Canadian Orthopaedic Association. We use CJRR and other data sources to understand aspects of joint replacement such as hospitalizations, patient demographics, clinical issues, wait times and outcomes.

Databases and data sources

Canadian Joint Replacement Registry

The Canadian Joint Replacement Registry (CJRR) was launched in May 2001 as a voluntary registry. Today, it is mandated in Ontario, Manitoba and British Columbia. CJRR contains data from surgeons or facilities in all provinces and territories except Prince Edward Island and Nunavut.

CJRR provides in-depth information on hip and knee replacement procedures in Canada, including prosthesis information. The registry contains patient-level data beyond what is collected in the Hospital Morbidity Database (HMDB), the Discharge Abstract Database (DAD) and the National Ambulatory Care Reporting System (NACRS).

Hospital Morbidity Database

The Hospital Morbidity Database (HMDB) captures administrative, clinical and demographic information about hospital inpatients in Canada.

Discharge Abstract Database

The Discharge Abstract Database (DAD) contains demographic, administrative and clinical data on inpatient hospital discharges.

National Ambulatory Care Reporting System

The National Ambulatory Care Reporting System (NACRS) contains demographic, administrative and clinical data for hospital- and community-based ambulatory care (for participating facilities).

National Rehabilitation Reporting System

The National Rehabilitation Reporting System (NRS) contains data on adult inpatients at rehabilitation facilities and programs in 9 provinces.


Metadata is information about data. It helps users understand and interpret data from a specific source.

Information for electronic file submitters

Please note: As of April 1, 2018, the Discharge Abstract Database (DAD) will accept CJRR hip and knee replacement prosthesis information in Group 20 based on instructions outlined in the 2018–2019 DAD Abstracting Manual. Jurisdictional reporting requirements to submit CJRR data via the DAD are determined based on discussions between CIHI and the ministries. Clients should contact their respective health region or ministry/department of health for details regarding reporting requirements.

Please contact a CIHI vendor support representative at help@cihi.ca for any inquiries about becoming a CJRR licensed vendor and obtaining the CJRR Electronic Data Submission Requirements.

Information for web-based data submitters

The CJRR web tool is being decommissioned in summer 2018

The CJRR web tool will be decommissioned in summer 2018 once 2017–2018 data has been processed. If you have any questions about this, please contact the appropriate person at your hospital or email the CJRR team at cjrr@cihi.ca.

CJRR Web-Based Data Submission and Reports Tool

The CJRR Web-Based Data Submission and Reports Tool is available for participating surgeons to submit data directly to CJRR through a secure online platform; data can also be updated using the tool. Select from the links below for a demonstration of the tool and training on how to use it.


Consent form

CIHI developed this form as a courtesy to data providers; however, data providers are responsible for determining whether consent is required and ensuring that the consent form used meets the requirements for their jurisdiction.

Historical forms

CJRR paper data submissions have been retired. As of procedures performed on April 1, 2013, CJRR accepts only electronic data submission. These forms are made available for reference use only.

The pre-MDS CJRR data collection forms were used for surgical procedures performed up to March 31, 2012. Effective April 1, 2012, CJRR has streamlined its data submission requirements to a minimum data set (MDS) aligned with those proposed by the International Society of Arthroplasty Registries (ISAR).

Advisory groups

In addition to partnering with Canada’s orthopedic surgeons across the country, CIHI is supported by 2 expert groups:

  • The CJRR Advisory Committee, chaired by Dr. Eric Bohm and co-chaired by Dr. Michael Dunbar, provides CIHI with advice on the development and implementation of CJRR
  • The CJRR Scientific Working Group, provides methodological advice on CJRR analytical studies 

CPD credits

Orthopedic surgeons who participate in CJRR on a voluntary basis may be eligible for continuing professional development (CPD) credits. For more information, contact us by email at cjrr@cihi.ca.
