Wait Times

Wait Times for Hip and Knee Replacement

There are many ways to report wait times.

  • The 90th percentile captures the wait time at which 90% of people received service. It provides a picture that is close to the maximum period one can expect to wait.
  • The median captures the time 50% of patients waited receive service, meaning half of all waiting patients received service and half waited longer. It provides a picture close to the typical wait one can expect.

In joint replacement care, there are two different “waiting” periods: the wait for the surgeon consult, and the wait to receive surgery. These are generally not passive waiting periods, since treatments and preparation for care are often delivered in this time.

Here are the wait times in Alberta for the past year.
