Wait Times for Hip and Knee Replacement


With joint replacements, we measure two different “waiting” periods:

  1. the wait for the surgeon consult, and
  2. the wait to receive surgery.

These are not passive waiting periods, since treatments and preparation for care are often delivered in this time.

There are several ways to describe waiting times; we use the following:

  • LONGEST 10%: (also called the 90th percentile) captures the point at which 90 percent of people received service. It describes the upper limit of time that one can expect to wait.
  • AVERAGE: mathematical mean; describes the typical wait one can expect.
  • SHORTEST 25%: the point at which the fastest quarter of people received service. This describes the quickest one can expect to wait.
