Name | Age-Standardized Rate for Knee Replacements (All Types) |
Short/Other Names |
Knee Replacement Rate |
Description | The age-standardized hospitalization rate for all knee replacement procedures performed on inpatients in acute care facilities (per 100,000 population age 20 and older). Analysis reflects all knee replacement types: total knee replacement, unicompartmental knee replacement (medial, lateral or patellofemoral) and patella-only procedures. |

Description: Unit of Analysis: Single admission Inclusions: CCI: 1.VG.53 and 1.VP.53 Note: Rates are based on the total number of discharges for knee replacement procedures in a given year. Therefore, a patient who received a simultaneous bilateral knee replacement or underwent multiple knee replacement procedures within a single hospital admission would be counted only once. 2. Age at admission: 20 and older 3. Sex recorded as male or female 4. Admission to an acute care institution 5. Canadian resident Exclusions: 2. Records with an invalid or unknown postal code/forward sortation area of residence 3. Knee replacement procedures (all types) that were abandoned after onset |
Background, Interpretation and Benchmarks | |
Rationale |
Knee replacement surgery has the potential to improve functional status, reduce pain and contribute to other gains in health-related quality of life. Over the past two decades, rates of knee replacement procedures have increased substantially. Wide inter-regional variation in joint replacement rates may be attributable to numerous factors, including the availability of services, provider practice patterns and patient preferences. |

Caveats and Limitations |
1. Due to small cell sizes, values reported from Yukon, the Northwest Territories and Nunavut are suppressed. However, their numbers are included in Canadian calculations. 2. Rates are based on the total number of discharges for knee replacement procedures in a given year. However, it is possible for a patient to undergo more than one knee replacement procedure in a single discharge. 3. Knee replacement procedures that were not performed in an acute care setting are not included in this indicator. |
