August 27, 2020 — The number of Canadians having joint replacements has increased over the past 5 years, with more than 137,000 surgeries now performed annually, estimated at $1.4 billion for inpatient hospital and physician costs (excluding rehabilitation). This includes revision surgeries (also known as repeat surgeries) which, compared with the primary surgery, are more complex, have greater risks and require patients to stay in hospital longer. Understanding the factors that influence and contribute to these revisions helps to support clinical best practices and improve patient outcomes.

Note: The following data and findings reflect the most recent information available from the 2018–2019 data cycle before the COVID-19 pandemic.

Key findings

  • More than 62,000 hip replacements and over 75,000 knee replacements were performed in Canada in 2018–2019. This represents an increase of 20.1% and 22.5%, respectively, over the last 5 years.
  • Almost 10,000 hip and knee revision surgeries were performed last year, with nearly 30% being revised due to infection.
  • The average inpatient cost for a revision surgery was more than $19,800 — almost 80% higher than the cost for a primary joint replacement (over $11,000).
  • Patients spent an average of 9 days in the hospital after a revision surgery (excluding rehabilitation). This is more than double the length of a hospital stay for a primary joint replacement.
